How DOT Compliance Services Find New Carrier Clients

Drug testing, BOC-3, UCR, IFTA, IRP, MCS-150 and audit rules for new carriers, mapped to the FMCSA file, with segment sizes, templates and safe outreach.

Published Oct 29, 2026 · 38 min read · by Lead Mining Company

A carrier that registers with the FMCSA this week has a short list of obligations it cannot skip. It needs a drug and alcohol testing program before its first CDL driver works. It needs a process agent on file if it applies for for-hire authority. It needs a UCR registration if it crosses state lines, fuel tax and apportioned plates once heavy trucks run in other states, an MCS-150 update every two years, and a safety audit within its first year of interstate operation. Each of those is a service that someone sells.

This guide is for the people who sell them: drug and alcohol testing consortiums and third-party administrators (C/TPAs), BOC-3 process agents, UCR, IFTA and IRP permit services, and safety consultants. It reads each rule at its source and maps it to the columns of the public FMCSA carrier file. It sizes each group of prospects from the counts as of October 28, 2026, and shows how to reach new carriers without looking like the government impersonation scams that FMCSA keeps warning carriers about. Truck insurance, factoring, dispatch, financing and the calling rules each have their own guide, linked where they come up.

Nothing here is legal advice. It is a reading of the published rules as of late October 2026, with a link to each one so you can check the text yourself.

What a new carrier owes in its first year

Start with the obligations and who they apply to. The answer decides which rows of a carrier list belong to your service and which you should skip.

First-year obligations of a new motor carrier and the rule behind each
Obligation	Rule	Who it applies to	When
Drug and alcohol testing, Clearinghouse	49 CFR Part 382	People who drive a commercial motor vehicle and need a CDL, and their employers	Before the first driver performs safety-sensitive work, then random tests through the year and an annual query
Process agent designation (Form BOC-3)	49 CFR Part 366	Motor carriers and brokers, in practice those filing for operating authority	With the authority filings
Unified Carrier Registration (UCR)	UCR Agreement	Interstate carriers, brokers, freight forwarders and leasing companies	Before January 1 of each registration year
Fuel tax license (IFTA)	IFTA Articles of Agreement	Qualified motor vehicles: over 26,000 pounds, or three or more axles	Before running in other jurisdictions, then quarterly returns
Apportioned plates (IRP)	International Registration Plan	Apportionable vehicles used in two or more member jurisdictions	Before running in other jurisdictions without trip permits
MCS-150 update	49 CFR 390.19T	Interstate carriers, and intrastate carriers that need a hazmat safety permit	Before operations, then every 24 months on a schedule set by the USDOT number
New entrant safety audit	49 CFR Part 385, subpart D; 49 U.S.C. 31144(g)	U.S. and Canadian carriers starting interstate operations	Inside an 18-month monitoring period; for property carriers, within 12 months of starting operations
Records of duty status, ELDs	49 CFR 395.8, checked at the audit under 385.321	Carriers whose drivers fall under the hours-of-service rules	From the first day of driving

One technical point before the detail. Several of these sections exist in two versions in the Code of Federal Regulations. The process-agent sections of Part 366 and the MCS-150 section of Part 390 were rewritten in October 2015 (80 FR 63705 and 80 FR 63711), and in January 2017 FMCSA suspended the rewritten text (82 FR 5303 and 82 FR 5316). The sections in force carry a "T" suffix: 366.1T through 366.6T for process agents and 390.19T for the MCS-150. The unsuffixed 390.19, as amended in 2023, covers only certain Mexico-domiciled carriers and is itself suspended. When your own material cites these rules, cite the T sections.

Drug and alcohol testing and the Clearinghouse under 49 CFR Part 382

For a consortium or third-party administrator, Part 382 is the whole product. It is also the rule a new carrier is most likely to get wrong, because it applies from the first day a driver works and because five of the sixteen automatic-failure items in the new entrant safety audit come from it.

Who Part 382 covers

Section 382.103(a) applies the part to every person who operates a commercial motor vehicle in commerce in any state and is subject to the commercial driver's license requirements of Part 383, and to the employers of those people. The test is the CDL, not whether the carrier crosses state lines. Do not drop the carriers marked intrastate from a consortium list until you know whether their drivers hold CDLs.

The owner-operator rule is in 382.103(b), and it is the reason most single-truck carriers need a consortium. An employer who employs himself or herself as a driver must meet both the employer and the driver requirements. An employer who employs only himself or herself as a driver "shall implement a random alcohol and controlled substances testing program of two or more covered employees in the random testing selection pool." A one-person company cannot run a pool of two people on its own. It joins a larger pool, and 382.305(j)(2) allows exactly that: an employer may use a service agent such as a C/TPA to make random selections, and its drivers may be part of a larger random testing pool of covered employees.

The pre-employment drug test

Under 382.301(a), before a driver performs safety-sensitive functions for an employer for the first time, the driver must take a controlled substances test, and the employer may not let the driver work until it has a verified negative result from the medical review officer or the C/TPA. There is a narrow exception in 382.301(b). The test can be skipped if the driver took part in a qualifying testing program within the previous 30 days and was tested within the past six months, or was in a random program for the previous 12 months, and no known prior employer has a violation on record within six months. An employer that uses the exception must collect and keep a list of verifications from the driver's previous program under 382.301(c). Pre-employment alcohol testing is optional under 382.301(d), with its own rules if the employer chooses it.

For a brand-new owner-operator, the practical reading is simple. The first loaded mile waits on a negative drug test result. That is the week-one sale.

The random testing pool

Section 382.305(b) sets the minimum annual random testing rates at 10 percent of the average number of driver positions for alcohol and 50 percent for controlled substances. FMCSA can lower or raise those rates based on industry violation and positive rates, by notice in the Federal Register, effective January 1 of the following year (382.305(c) through (h)). Check the current year's rate before you quote it in a sales letter.

The rest of 382.305 describes what a pool has to do. Selection must use a scientifically valid method, such as a random number generator matched to driver identifiers. Every driver must have an equal chance each time selections are made, and a selected driver must be tested in that selection period (382.305(i)). Tests must be unannounced and spread reasonably through the calendar year (382.305(k)). A driver notified of selection goes to the collection site immediately (382.305(l)). An employer that uses a C/TPA must still make sure the service agent tests at the right rate and keeps only covered employees in the pool (382.305(j)(2)).

A worked example shows the volume. A consortium pool that averages 1,000 driver positions over the year must, at the 50 percent and 10 percent rates in 382.305(b), run at least 500 random drug tests and 100 random alcohol tests in that year (1,000 x 0.50 and 1,000 x 0.10), spread across the year rather than bunched in December.

Clearinghouse registration and queries

Section 382.711(a) requires each employer and service agent to register with the Drug and Alcohol Clearinghouse before accessing or reporting information in it. An employer's registration includes its name, address, phone and USDOT number, the people it authorizes to report or query, and, under 382.711(b)(3), the C/TPA or other service agent it uses, with authorization for that agent to query or report. A change to the C/TPA designation must be updated within 10 days, and the list of authorized people must be verified every year.

Two queries follow from that registration. Under 382.701(a), an employer must run a pre-employment full query of the Clearinghouse before a driver performs a safety-sensitive function. A full query releases the driver's information and needs the driver's specific consent. Under 382.701(b), the employer must query the Clearinghouse at least once a year for every driver subject to testing. A limited query, with the driver's consent, satisfies the annual requirement. If it shows that information exists, the employer must run a full query within 24 hours or take the driver off safety-sensitive work until it does. Section 382.701(d) bars an employer from using a driver whose query shows a verified positive, adulterated or substituted test, an alcohol result of 0.04 or higher, a refusal, or a reported violation.

Why Part 382 decides the safety audit

Section 385.321(b) of the new entrant rules lists 16 violations that cause automatic failure of the new entrant safety audit. The first five are Part 382 violations, and each one fails the audit on a single occurrence:

382.115(a) or (b): failing to implement an alcohol and/or controlled substances testing program.
382.201: using a driver known to have an alcohol concentration of 0.04 or greater.
382.211: using a driver who refused a required test.
382.215: using a driver known to have tested positive for a controlled substance.
382.305: failing to implement a random testing program.

Under 385.321(a), failing the audit leads to a notice that the carrier's new entrant registration will be revoked. A consortium that can show a new carrier its enrollment certificate, its Clearinghouse designation and its pre-employment result sitting in one folder is selling against that outcome, and can say so without exaggeration.

What a consortium sells, and when

Week 1: enrollment in a random pool, the pre-employment drug test, Clearinghouse registration with the C/TPA designated, and the pre-employment full query.
Month 1: written policy and records the audit will ask for, and a plan for any second driver the carrier hires.
Months 3 to 12: random selections through the year, the annual query before the first anniversary, and records ready for the safety audit.

BOC-3 process agents under 49 CFR Part 366

Part 366 governs the designation of people on whom court papers can be served. Under 366.1T it applies to motor carriers and brokers. The designation is made on Form BOC-3, Designation of Agent for Service of Process, and under 366.2T only one completed, current form may be on file. It must include every state for which a designation is required, and the carrier keeps a copy at its principal place of business.

Section 366.4T sets the states. A motor carrier must designate an agent for each state in which it is authorized to operate and each state it crosses during those operations. A broker designates for each state where it has offices or writes contracts. Section 366.5T allows a blanket designation: where an association or corporation has filed a list of process agents for each state with FMCSA, a carrier can designate everyone on that list for the states it is or may be authorized to operate in, including states crossed. A process-agent company that has filed such a list sells carriers the right to name it. Under 366.6T a designation can be canceled or changed only by a new designation, except that it may be dropped once the carrier has not been subject to 366.4T for a year.

The link to authority runs through 49 CFR 385.301(a): before a carrier begins interstate operations it must register and receive a USDOT number, and for-hire carriers must also obtain operating authority unless their transportation is exempt. The carriers applying for authority carry an MC, MX or FF docket number in the census file.

Be exact about what the requirement is. FMCSA's page on misleading marketing to new applicants says that while FMCSA requires financial responsibility and evidence of a process agent for many entities, "the U.S. Government does not endorse and generally does not require the use of private businesses or vendors." The rule requires a designation. It does not require your company. A letter that says a carrier "must use" a particular agent is a misstatement.

Who the process-agent prospects are

Filter for rows with an MC docket and For hire set to yes. As of October 28, 2026, 71,307 of the 178,190 active carriers registered since October 1, 2025 had an MC, MX or FF docket, which is 40.0 percent. A docket in the file means the carrier filed for authority. It does not prove that FMCSA granted the authority or that it is active now, and the file does not show whether a BOC-3 is already on file. Treat the newest docket holders as the first calls and expect some to have filed already.

In this guide, "new authority" means a carrier that registered in the last 90 days and has an MC, MX or FF docket in the file. Nothing more than that.

The docket share varies a lot by state, which matters if you sell in one region. In the file as of October 28, 2026, 61.5 percent of new Illinois carriers had a docket (3,778 of 6,144), 52.6 percent in Ohio (3,168 of 6,020) and 19.8 percent in New York (1,607 of 8,122). A process agent working New York should expect about one docket for every five registrations, against three in five in Illinois.

UCR annual registration and the 2027 fees

The Unified Carrier Registration Plan's own fee page sets out the timing. Every entity subject to UCR registers each year with its base state and pays an annual fee to that state. To keep operating legally it must complete registration and pay before January 1 of the registration year; after that date the fee is still due, but a non-registrant may face state enforcement. The 2027 registration portal, run through the National Registration System, opened on October 1, 2026, and the 2027 fees took effect the same day.

Who must register comes from the Plan's screening questions. A carrier engaged only in intrastate commerce is told it is not required to register, and so is a private carrier of passengers, such as a church, school or business moving its own employees. For-hire passenger carriers are required to register. An entity in interstate commerce counts every commercial motor vehicle with a gross combination weight or rating of 10,001 pounds or more and pays the fee for its bracket.

UCR fees per entity by vehicles owned or operated, from the UCR Plan's fee page (motor carrier or freight forwarder column)
Bracket	Vehicles	2026 fee	2027 fee	Change
B1	0 to 2	$46	$55	+$9 (19.6%)
B2	3 to 5	$138	$167	+$29 (21.0%)
B3	6 to 20	$276	$333	+$57 (20.7%)
B4	21 to 100	$963	$1,163	+$200 (20.8%)
B5	101 to 1,000	$4,592	$5,548	+$956 (20.8%)
B6	1,001 and more	$44,836	$54,165	+$9,329 (20.8%)

The percentages are our arithmetic from the two fee tables, for example $55 divided by $46 is 1.196. Brokers and leasing companies pay the B1 fee, $55 for 2027 and $46 for 2026. A carrier that budgets from last year's fee will come up short by the increase: $9 in the smallest bracket and $57 in the 6-to-20 bracket.

Mapping the file to UCR brackets

Two columns decide a UCR prospect: Operation (interstate or not) and Power units (the bracket). As of October 28, 2026, 102,308 of the 178,190 carriers in the file were marked interstate (57.4 percent). The other 75,882 (42.6 percent) were intrastate, hazmat or not, and the Plan's screener tells purely intrastate carriers they do not need UCR.

The fleet bands in the file line up with the brackets in two places. "One power unit or none" (122,643 carriers) sits inside B1. "Six to 20" (7,079 carriers) is exactly B3. "Two to five" (46,926 carriers) straddles B1 and B2: a two-truck carrier pays the B1 fee and a three-truck carrier pays B2. "21 or more" (1,542 carriers) is B4 and up. Note also that UCR counts vehicles owned or operated, and the file's power units are what the carrier reported at registration, so confirm the count before you quote a fee.

If the interstate share is the same in every fleet band, about 70,416 interstate carriers in the file run one power unit or none (102,308 x 122,643 / 178,190), and each owes the $55 B1 fee for 2027. That is an estimate; the file gives no cross-count of operation by fleet size.

What a UCR service actually sells

The UCR fee page says registration "is relatively simple and can be completed online." A carrier can do it alone. A filing service sells the reminder, the correct bracket, a second check of the vehicle count and the time saved, and should price that service separately from the state fee. The season is October 1 through December 31. A carrier that registered with the FMCSA in, say, March 2026 and runs interstate faces its first renewal decision this quarter.

IFTA and IRP thresholds

Fuel tax and apportioned registration are separate programs with the same weight line. Both matter only to carriers whose trucks leave their home jurisdiction, and both turn on facts the carrier file does not hold: axles and weight.

IFTA: the qualified motor vehicle

The IFTA Articles of Agreement (edition effective January 2026), section R245, define a qualified motor vehicle as a motor vehicle used, designed or maintained for transporting persons or property that has two axles and a gross vehicle weight or registered gross vehicle weight over 26,000 pounds (11,797 kilograms), or has three or more axles regardless of weight, or is used in combination when the weight of the combination exceeds 26,000 pounds. Recreational vehicles are excluded.

A licensee reports through its base jurisdiction, defined in R212 as the member jurisdiction where its qualified vehicles are based for registration, where its operational records are kept or can be made available, and where some of the fleet's travel happens. Under R227 a jurisdiction is a U.S. state, the District of Columbia, a Canadian province or territory, or a Mexican state. Under R254 the reporting periods are calendar quarters, and under R960 each return and full payment are due on the last day of the month after the quarter ends, moving to the next business day when that day falls on a weekend or legal holiday.

That gives four dates a year: April 30, July 31, October 31 and January 31. The third-quarter 2026 return is due October 31, 2026, which is a Saturday, so under R960 it moves to Monday, November 2. The fourth-quarter return is due January 31, 2027, a Sunday, so it moves to Monday, February 1. A carrier that has never filed a quarterly return is a natural client in the weeks before each of those dates.

IRP: the apportionable vehicle

The International Registration Plan's definition, as published by the Wyoming Department of Transportation, says an apportionable vehicle is any power unit used or intended for use in two or more member jurisdictions that carries people for hire or is designed, used or maintained primarily to carry property, and that has two axles and a gross or registered gross vehicle weight over 26,000 pounds, or three or more axles regardless of weight, or is used in a combination over 26,000 pounds. Recreational vehicles, vehicles with restricted plates and government-owned vehicles are not apportionable. Trucks and tractors at 26,000 pounds or less may register under the Plan at the registrant's option. Full reciprocity lists every member jurisdiction on the cab card, so the carrier runs in all of them without buying trip permits.

Mapping the file to IFTA and IRP

The census file shows Operation and Power units. It does not show axles, weights or trailer combinations. The 102,308 interstate carriers are the outer edge of the market, not the market. A carrier running a light pickup and a small trailer under 26,000 pounds combined may need neither program. A carrier running a three-axle tractor across state lines meets both definitions. The qualifying question on the first call is short: what is the combined weight of your truck and trailer, and how many axles does the truck have?

The MCS-150 biennial update

Section 390.19T is the rule in force for U.S. carriers. Under 390.19T(a) every U.S., Canadian, Mexican or other foreign-domiciled motor carrier in interstate commerce files Form MCS-150, the Motor Carrier Identification Report. An intrastate carrier that needs a hazardous materials safety permit under Part 385 subpart E files the combined Form MCS-150B instead.

Under 390.19T(b) the carrier files before it begins operations and then every 24 months on a schedule set by its USDOT number. The last digit sets the month the update is due, by its last day: 1 is January, 2 is February and so on, with 9 for September and 0 for October. The next-to-last digit sets the year: odd means odd-numbered calendar years and even means even-numbered years.

Worked example: a carrier whose USDOT number ends in 87 files by July 31 (last digit 7) in even-numbered years (next-to-last digit 8), so in 2026, 2028 and 2030. A carrier whose number ends in 30 files by October 31 in odd-numbered years: 2027, 2029, 2031. The due date comes from the number, not from the anniversary of the carrier's registration, so a service can calendar every carrier on its list the day it downloads it.

The penalties are in 390.19T(b)(4) and (g). A carrier that fails to complete the biennial update is subject to the civil penalties in 49 U.S.C. 521(b)(2)(B) or 49 U.S.C. 14901(a) and to deactivation of its USDOT number. A carrier that fails to file or files false or misleading information is subject to the 521(b)(2)(B) penalties. Section 390.19T(i) exempts a carrier that registers its vehicles in a state taking part in the PRISM program, provided it files all the required information with that state's office.

The form itself costs nothing. FMCSA's page on misleading marketing says it does not charge a fee for its downloadable forms. A filing service sells the reminder, the accuracy check and the filing, and should say that plainly.

How many updates come due each month

Assume the last two digits of the USDOT numbers in the file are spread evenly. That is an assumption, not a published figure, so check it against your own download. On that assumption, about one interstate carrier in ten has a given due month and about half of those are due in a given year. Applied to the 102,308 interstate carriers in the file, that is about 5,115 updates due in any one month of the right year (102,308 x 0.1 x 0.5). It is an estimate, and it covers only carriers registered since October 1, 2025.

The new entrant safety audit and the 18-month monitoring period

Subpart D of Part 385 is the New Entrant Safety Assurance Program. Section 385.301 says that before a motor carrier of property or passengers begins interstate operations it must register with FMCSA and get a USDOT number, and for-hire carriers must also get operating authority unless their transportation is exempt. The subpart applies to carriers domiciled in the United States and Canada.

Section 385.307 sets the periods. After a new entrant meets all pre-operational requirements, it is monitored for 18 months. During that time its roadside performance is watched, and a safety audit is conducted once it has operated long enough to have records that show whether its basic safety management controls work. That period "will generally be at least 3 months." All records the audit needs must be available on request to a certified auditor.

The statute adds a deadline. 49 U.S.C. 31144(g)(1) requires a safety review no later than 12 months after a new owner or operator begins operations under its registration, and no later than 120 days for a new passenger carrier. Household goods carriers also face a consumer protection standards review within 18 months under 31144(g)(6). Read together, the audit window for a property carrier opens around month three and closes by month twelve after it starts operating. The census file shows the registration date, not the day the first load moved, so treat the window as approximate.

The 16 automatic-failure items

Section 385.321(b) lists them. A single occurrence fails the audit for every item except two that use a threshold of 51 percent or more of examined records. They group into six areas a safety consultant can check in advance:

Drug and alcohol (5 items): no testing program (382.115), using a driver at 0.04 or more (382.201), using a driver who refused a test (382.211), using a driver who tested positive (382.215), no random program (382.305).
Licensing (3 items): knowingly using a driver without a valid CDL (383.3(a), 383.23(a)), allowing a driver with a disqualified CDL or learner's permit to operate (383.37(b)), allowing a disqualified driver to drive (383.51(a)).
Insurance (2 items): operating without the required minimum financial responsibility (387.7(a)), or for passenger carriers under 387.31(a).
Driver qualification (2 items): knowingly using a disqualified driver (391.15(a)) or a physically unqualified driver (391.11(b)(4)).
Hours of service (1 item): failing to require a driver to make a record of duty status (395.8(a)), at the 51 percent threshold.
Vehicles (3 items): operating a vehicle declared out of service before repairs (396.9(c)(2)), not correcting out-of-service defects listed on a driver vehicle inspection report (396.11(a)(3)), and using a vehicle not periodically inspected (396.17(a)), the last at the 51 percent threshold.

Under 385.321(a), failing leads to a notice that the carrier's new entrant registration will be revoked. A mock audit against those 16 items before the audit window opens is a product a new carrier can understand in one sentence. The insurance items connect to the guide for truck insurance agents, which covers the 49 CFR 387 minimums.

How many carriers are in the audit window

Every interstate carrier in the file is inside its 18 months, because the file starts at registrations on October 1, 2025, about 13 months before October 28, 2026. Of the 178,190 carriers, 138,299 registered more than 90 days ago (178,190 minus the 39,891 registered in the last 90 days). If the file-wide interstate share (102,308 of 178,190) holds for them, about 79,405 interstate carriers sit in the stretch where audits usually happen. That is an estimate built on the file-wide interstate share.

ELD and records of duty status

Records of duty status belong to ELD vendors more than to compliance services, and they have their own page with the device rules and exceptions. For a safety consultant the point is narrower: 385.321 makes 49 CFR 395.8(a), failing to require a driver to make a record of duty status, an automatic failure of the new entrant audit when 51 percent or more of the examined records fail. A pre-audit review that pulls a sample of the carrier's logs, checks that a record exists for each day a driver worked, and fixes the gaps before the auditor asks is the service. Check whether the carrier's drivers fall under an exception to the ELD rule before you sell a device or a review built around one.

Matching each service to the fields in the carrier file

Our cleaned carrier file has these columns, and the raw census holds the same information under its own field names: USDOT number, MC docket, legal and DBA name, company officer, phone, cell phone, email, physical and mailing address, Registered (the census add date), Operation, For hire, Power units, Drivers, Hazmat and Cargo. The table below shows which of them qualify a carrier for each service. A dash means the field does not narrow the list.

Carrier file fields that qualify a prospect, by service
Service	Interstate or intrastate	For hire	Power units and drivers	Hazmat	What the file cannot tell you
Drug and alcohol consortium or C/TPA	Both (Part 382 follows the CDL)	-	1 power unit marks owner-operators who need a pool of two or more; Drivers sizes the pool	-	Whether the drivers hold CDLs
BOC-3 process agent	Interstate	Yes	-	-	Whether a BOC-3 is already on file; whether authority is active
UCR filing	Interstate only	Both; the Plan exempts private passenger carriers	Power units sets the bracket	-	Vehicles owned or operated today
IFTA and IRP	Interstate	-	Power units sets the number of vehicles to license and plate	-	Axles and weight
MCS-150 updates	Interstate; intrastate hazmat with a permit	-	-	With intrastate operation, flags carriers that may need the MCS-150B (safety-permit carriers only)	Whether the carrier already updated
Safety consultant, audit preparation	Interstate	-	Drivers shows how many qualification files and logs to review	Yes adds hazmat-specific work	The audit date; inspections and crash history

The file has no insurance status, no authority grant date, no inspection results and no crash history. "Registered" is the date the FMCSA added the carrier to its census, which is the clock this guide uses.

Timing by service

When each service fits a new carrier, counted from the Registered date
Service	Week 1	Month 1	Months 3 to 12
Consortium or C/TPA	Pool enrollment, pre-employment test, Clearinghouse registration and full query	Policy and records; second-driver plan	Random selections, annual query, audit records
Process agent	Blanket BOC-3 for carriers still assembling authority filings	Follow-up with docket holders that have not filed	Rarely; a new designation only when the carrier changes it
UCR service	Interstate carriers starting operations	Bracket check against the vehicle count	Renewal season, October 1 to December 31
IFTA and IRP service	Licensing and plates before trucks leave the base jurisdiction	Recordkeeping setup for miles and fuel by jurisdiction	Quarterly returns due April 30, July 31, October 31 and January 31
MCS-150 service	Calendar the due month from the USDOT digits	-	Reminder about 60 days before the due month
Safety consultant	Introductory contact only	Driver files and maintenance records setup	Mock audit against the 16 items before month three, and again before month twelve

How many new carriers each service can reach

All counts below are from the FMCSA Company Census File as of October 28, 2026, counting active carriers whose census add date is October 1, 2025 or later. Where a line is an estimate, it says so and shows the arithmetic.

The flow of new carriers

178,190 active carriers registered from October 1, 2025 through October 28, 2026.
39,891 registered in the last 90 days, and 11,218 in the last 30.
That is about 13,297 a month (39,891 / 3) and about 3,103 a week (39,891 / 90 x 7).
The busiest month in the file was March 2026 with 16,414 registrations; the quietest full month was November 2025 with 10,257. October 2026 had 10,192 through October 28.
177,751 list a phone (99.8 percent), 177,954 an email (99.9 percent) and 29,448 a separate cell phone (16.5 percent).

Segment sizes by service

The monthly figures below take the 90-day pace of 13,297 new carriers a month and multiply it by each segment's share of the whole file. They assume the last 90 days look like the last 13 months, so they are estimates.

Segments in the file and estimated new carriers per month, as of October 28, 2026
Segment	Service	Carriers in file	Share	Estimated new per month
One power unit or none	Consortium (owner-operator pools)	122,643	68.8%	9,152
Two to five power units	Consortium, UCR B1/B2	46,926	26.3%	3,502
Six to 20 power units	UCR B3, safety consultants	7,079	4.0%	528
21 or more power units	C/TPA employer accounts	1,542	0.9%	115
MC, MX or FF docket	Process agents	71,307	40.0%	5,321
Interstate	UCR, IFTA, IRP, MCS-150, audit prep	102,308	57.4%	7,634
Authorized for hire	Process agents (with a docket)	130,839	73.4%	9,764
Hazmat	Hazmat safety consultants, MCS-150B	12,225	6.9%	912

Example of the arithmetic: 13,297 x (71,307 / 178,190) = 13,297 x 0.4002 = 5,321 new docket holders a month. The fleet bands add up to the full 178,190, so the first four rows cover every carrier exactly once.

The largest states

Most compliance services are licensed, staffed or known in a region. The ten states with the most registrations in the last 90 days, as of October 28, 2026:

New carriers by state, ten largest by 90-day registrations
State	Last 90 days	Per week	One power unit or none	MC docket	Hazmat
Texas	4,860	374	69.8%	40.3%	1,225
California	4,282	329	74.7%	36.2%	850
Florida	3,385	260	73.8%	38.2%	1,282
Georgia	1,870	144	69.7%	38.3%	593
Pennsylvania	1,793	138	68.4%	45.3%	564
New York	1,732	133	65.4%	19.8%	428
Illinois	1,501	115	72.8%	61.5%	353
New Jersey	1,445	111	69.2%	44.5%	325
Ohio	1,392	107	71.9%	52.6%	471
North Carolina	1,276	98	67.6%	43.7%	398

"Per week" is the 90-day count divided by 13 weeks. The share columns and the hazmat count use each state's full file since October 1, 2025. Florida has more hazmat carriers in the file than Texas (1,282 against 1,225) on about 71 percent of Texas's total (14,906 against 20,972), which is worth knowing if you sell hazmat compliance in the Southeast.

Building the list for free from data.transportation.gov

Everything above comes from a public dataset you can download yourself at no cost: the FMCSA Company Census File on the U.S. DOT open data portal (dataset az4n-8mr2). There is no login. The full file holds millions of rows, so filter before you download.

Open the dataset's API endpoint, https://data.transportation.gov/resource/az4n-8mr2.csv, with a filter in the URL. Dates in the add_date column are stored as text in YYYYMMDD form, so a filter like $where=add_date >= '20261001' AND status_code = 'A' AND phy_state = 'TX' returns active Texas carriers added since October 1. Add &$limit=50000 so the export is not cut at the default page size.
Keep the columns a compliance service needs: dot_number, docket1prefix, docket1, legal_name, dba_name, company_officer_1, phone, cell_phone, email_address, phy_street, phy_city, phy_state, phy_zip, add_date, carrier_operation, classdef, power_units, total_drivers, total_cdl and hm_ind.
Read carrier_operation as the operation type: A is interstate, and B and C are the two intrastate codes (hazmat and non-hazmat).
Use total_cdl if you run a consortium. It is the field closest to the Part 382 question, and it is in the raw census even though our cleaned file reports total drivers instead.
Repeat the pull on a schedule. A carrier that registers tomorrow will not be in a file you pulled this morning.

The step-by-step version, with the docket and for-hire fields, is in the guide to getting a list of new trucking companies from FMCSA data. What a prepared file saves is the repeat work: writing and rerunning the query, normalizing phone formats, decoding the operation codes, folding the separate cargo flag columns into one list, dropping inactive rows, and doing it again next week. If you have a developer and a spare afternoon each week, the free route works.

Outreach that cannot be mistaken for government mail

This is the part of the job where compliance services face a problem no other vendor has. Your product is a government requirement, your prospect is a week-old company, and its inbox is already full of messages pretending to be the government. A compliance service has to be more obviously private than anyone else selling to new carriers.

What FMCSA tells new carriers about vendors

FMCSA's page on fraudulent and misleading marketing to new applicants tells carriers three things about the agency itself: FMCSA does not contact carriers through telemarketers or robocalls, does not ask for credit card numbers by phone, and does not charge a fee for its downloadable forms. It explains that FMCSA publishes carrier contact details under the government's open data policy, so "you may get a call from someone offering you their services to assist with motor carrier registration or compliance. These calls are not from FMCSA." It asks carriers to report aggressive or misleading telemarketers that pose as FMCSA or USDOT to the Federal Trade Commission.

FMCSA's fraud alerts page lists the forms the impersonation takes. Its alerts include a "Bogus Compliance Notice," a "Fake Safety Audit," a "Fake FMCSA Notice," a "Fraudulent Action Required Notice," a "Bogus Notice of Carrier Status" claiming the carrier's profile is "not authorized," "Impersonating Government Officials" and "Aggressive Telemarketing." Several of those titles describe exactly the service a real compliance company sells. One alert concerns drug and alcohol testing directly: scammers posing as substance abuse professionals or employers get drivers to share their CDL number, date of birth and name, then enter fraudulent Clearinghouse violations on the driver's record unless they are paid.

The consequence for your outreach: a new carrier that hears "compliance notice," "action required" or "safety audit" from an unknown sender has been told by FMCSA to assume it is a scam. Write so that no one could mistake you for the agency, and so that a careful owner can check who you are in a minute.

What the FTC impersonation rule prohibits

The FTC's Government and Business Impersonation Rule, 16 CFR Part 461, makes it an unfair or deceptive practice under 461.2 to materially and falsely pose as a government entity or officer, directly or by implication, or to materially misrepresent affiliation with a government entity, including endorsement or sponsorship. "Government" includes federal, state, local and tribal governments and their agencies. "Materially" means likely to affect a person's choice of, or conduct regarding, goods or services. Section 461.3 applies the same test to impersonating a business, which matters if your mailer borrows a well-known trucking brand's look. "By implication" is the phrase to remember: the rule reaches a seal-like logo, an agency-like company name or a "notice" layout even if no sentence says you are the government.

Postal rules for mail that looks official or looks like a bill

39 U.S.C. 3001 has three provisions a compliance mailer can trip.

Subsection (h) covers a solicitation by a nongovernmental entity for the purchase of or payment for a product or service that "reasonably could be interpreted or construed as implying any Federal Government connection, approval, or endorsement" through a seal, insignia, citation to a federal statute, name of a federal agency, department, commission or program, trade or brand name, or any other term or symbol. Such mail is nonmailable unless it carries, on its face and in conspicuous type, the notice "THIS PRODUCT OR SERVICE HAS NOT BEEN APPROVED OR ENDORSED BY THE FEDERAL GOVERNMENT, AND THIS OFFER IS NOT BEING MADE BY AN AGENCY OF THE FEDERAL GOVERNMENT," the envelope carries "THIS IS NOT A GOVERNMENT DOCUMENT," and nothing falsely implies that federal benefits or services depend on buying (or the sender really has the connection, or the mail sits inside a publication the addressee asked for).
Subsection (i) applies the same rule to mail that asks for information, contributions or membership fees. A consortium that sells "membership" should read both.
Subsection (d) covers solicitations in the form of a bill, invoice or statement of account due. Such mail is nonmailable unless it carries a conspicuous notice that it is a solicitation for goods or services and not a bill, invoice or statement of account due, and that the recipient has no obligation to pay unless it accepts the offer. A UCR mailer that leads with "2027 amount due: $55" plus a service fee is the obvious risk.

Note what (h) names as a trigger: a citation to a federal statute and the name of a federal agency or program. A compliance letter naming FMCSA and quoting Part 382 can meet that test if the overall look implies a connection. The safest design does not imply one at all, and carries both disclaimers anyway if it names an agency or a rule.

A checklist for every letter, email and call

Your company's real name, logo, street address, phone and website are the first thing the reader sees. No eagle, shield, flag, seal or star that resembles an agency mark.
No company or product name that sounds like an agency or program, such as anything built from "Federal," "Department," "DOT," "Registration Office" or "Compliance Center."
No subject lines or headlines that copy the scams FMCSA lists: no "Notice," "Action Required," "Final Notice," "Carrier Status," "Safety Audit Scheduled" or "Validation Required."
Say in the first two lines that you are a private company and not FMCSA, DOT or any government agency.
Separate government fees from your fee, with the source of the government fee named, and say the carrier can file on its own.
Never ask for a USDOT PIN, Social Security number, bank details or a driver's CDL number and date of birth in a first contact. Collect what enrollment needs after the carrier signs, through your own secure intake.
If the mail names FMCSA or cites a federal rule, print the 3001(h) notices on the piece and on the envelope. If it shows any amount owed, print the 3001(d) notice.
Give a way to check you that does not depend on your letter: your website, your physical office and a callback number answered by a person.

Templates and a call script

These are starting points. Fill the bracketed parts with your own details, keep prices current, and have counsel review anything you mail at scale. The calling and texting rules are covered in detail in the rules for calling, texting and emailing new trucking companies. In short: many new carriers are owner-operators on personal cell phones, so the TCPA and the National Do Not Call Registry apply. Scrub against the registry and your own do-not-call list, dial by hand, use no autodialer and no prerecorded or AI voice, and send no texts without prior consent. Email follows CAN-SPAM. Mail is the lowest-risk channel.

First email

Under 15 U.S.C. 7704, a commercial email needs a subject line that does not mislead about the content, clear identification that it is an advertisement or solicitation, a working opt-out, and a valid physical postal address. An opt-out request must be honored within 10 business days.

Subject: Drug testing consortium for [Legal name], from [Your company]

Hello [Officer first name],

This is an advertisement from [Your company], a private drug and alcohol testing consortium in [City, State]. We are not FMCSA, DOT or any government agency.

We saw that [Legal name] registered with the FMCSA in [month]. If your drivers hold CDLs, 49 CFR Part 382 requires a negative pre-employment drug test before a new driver's first safety-sensitive work, and a one-driver company has to be in a random pool of at least two drivers. That is what we run.

Enrollment is $[price] a year per driver. It includes the pool, the pre-employment test at [number] collection sites in [State], and setup of your Clearinghouse account with us named as your C/TPA. You can check us at [website] or call [phone]; a person answers.

If this is not useful, reply "no" or use the link below and we will not write again.

[Name], [Title]
[Your company], [street address, city, state, ZIP]
[Unsubscribe link]

Change two lines for other services. A process agent writes: "If you are applying for operating authority, FMCSA requires a process agent designation on Form BOC-3. The rule requires the designation, not a particular company. Our blanket designation covers [states] for $[price]." A UCR service writes: "The UCR Plan's 2027 fee for 0 to 2 vehicles is $55, paid to your base state. You can register yourself online. Our service, $[price], files it, checks your vehicle count against your bracket and reminds you next October."

Letter or postcard

[Your company logo, name, street address, phone, website at the top]

We are a private company. We are not the FMCSA, the U.S. DOT or any government agency, and this is not a bill.

[Legal name] registered with the FMCSA on [Registered date]. New interstate carriers face a safety audit, generally after at least three months of operation and, for property carriers, within twelve months of starting operations. We review your driver files, drug and alcohol records, logs and maintenance records against the 16 items that fail an audit automatically, and give you a written list of what to fix. Price: $[price], fixed.

Call [phone] or visit [website]. To stop mail from us, call or write to the address above.

THIS PRODUCT OR SERVICE HAS NOT BEEN APPROVED OR ENDORSED BY THE FEDERAL GOVERNMENT, AND THIS OFFER IS NOT BEING MADE BY AN AGENCY OF THE FEDERAL GOVERNMENT.

Print "THIS IS NOT A GOVERNMENT DOCUMENT" on the envelope when the piece names FMCSA or cites a federal rule, as this one does.

Call script

Dial by hand, after the scrub, at a reasonable hour in the carrier's time zone. Many owner-operators will be driving, so keep it short and offer to call back.

Who you are: "Hi, this is [name] with [Your company]. We're a private drug and alcohol testing company in [city]. I'm not calling from the DOT or FMCSA. Is this [officer name]?"
Permission: "Is now a safe time for two minutes, or should I call back?" If they are driving, ask for a better time and hang up.
Why you called: "I saw [Legal name] registered with the FMCSA in [month]. Do your drivers need CDLs for the trucks you run?" If no, thank them and stop: Part 382 may not apply.
Qualify: "Do you have a testing program and a random pool set up yet? Has anyone run your Clearinghouse pre-employment query?"
Offer: "We can enroll you today. It's $[price] a year per driver, and a pre-employment test at a site near [city]. I can email the details so you can check us out first."
No pressure, no data: do not ask for a card number, a USDOT PIN or a driver's CDL number and date of birth on this call. Send the enrollment link by email.
Close: "If you'd rather not hear from us again, say so and I'll take you off our list." Then do it, the same day.

Follow-up schedule

Day 1 to 7 after registration: email, then a call after the scrub. Consortiums and process agents lead here.
Day 30: one follow-up email or a letter. IFTA and IRP services lead here.
Day 60 to 90: safety consultants send the audit-preparation letter.
October to December: UCR services contact every interstate carrier on file, new or not.
About 60 days before each MCS-150 due month: one reminder per carrier, by the USDOT digits.

Stop sooner for anyone who says no, and keep the record that you did.

Mistakes compliance services make with new carrier lists

Mail that looks official. Seals, agency-sounding names, "notice" layouts and red "final" stamps are what the FMCSA scam alerts describe, and they invite trouble under 16 CFR 461.2 and 39 U.S.C. 3001(h). They also lose the careful owners who would have been good clients.
Saying the carrier must use you. The rules require a testing program, a process agent designation, a UCR registration or an MCS-150 update. They do not require a particular vendor, and FMCSA says so in writing.
Blending fees. A single "UCR fee: $155" that hides a $100 service charge on a $55 state fee reads as deception when the carrier finds the Plan's fee page. Show both lines.
Pitching Part 382 to carriers without CDL drivers. Many small carriers run vehicles that may not need a CDL. Ask first, and use total_cdl from the raw census where you have it.
Treating an MC docket as active authority. The docket shows a filing. Confirm status before you build an offer on it.
Sending UCR offers to intrastate-only carriers. The UCR Plan tells them they are not required to register. The 75,882 carriers in the file not marked interstate are the wrong list for that offer.
Assuming every interstate carrier needs IFTA and IRP. Both turn on axles and a 26,000-pound line the file does not show.
Collecting personal data cold. Asking a stranger for a CDL number and date of birth looks exactly like the fraudulent-SAP scheme FMCSA describes. Do it only after enrollment, through a secure form.
Autodialers, prerecorded or AI voices, and texts without consent. Owner-operator phones are often personal cell phones, which brings the TCPA and the Do Not Call rules into every call and text.
Calling once. Each obligation has its own date. A carrier that ignored a consortium offer in week one may want an audit review in month four and a UCR filing in November.
Promising an audit pass. A consultant can check the 16 items and fix records. The audit result is FMCSA's.
Citing suspended rules. Cite 366.2T through 366.6T and 390.19T, not the suspended unsuffixed sections.

Where Lead Mining Company's carrier file fits

We are a private company, and nothing we sell is connected to the FMCSA or the U.S. DOT. Our new trucking companies file is the public census, filtered to active carriers registered since October 1, 2025 and refreshed every six hours, with the columns listed above in a clean CSV. You can filter by state, registration date, for-hire status, hazmat, power units and cargo before you download.

$99 a month: new trucking companies in every state, up to 25,000 rows a month. At the recent pace of about 13,297 new carriers a month nationally, one month of new registrations fits under the cap.
$149 once: carriers registered in the last 90 days (39,891 as of October 28, 2026), downloadable for 7 days after payment.
Custom software from $1,500: for example, a tool that computes each carrier's MCS-150 due month from its USDOT digits and loads the reminders into your CRM. See custom software for logistics and freight.

Prices are on the pricing page. The file does not include insurance status, authority grant dates, inspections, crash history, BOC-3 or UCR status, or vehicle weights; it holds what the carrier reported at registration.

Other buyers of the same file work different parts of a new carrier's first year: insurance agents, factoring companies (see also the factoring guide), dispatch services (and how dispatchers find carriers), truck and trailer dealers and lenders (see truck financing leads). The trucking and logistics industry page lists the rest.

Questions and answers

Which new trucking companies need a drug and alcohol testing consortium?

Part 382 applies to people who drive a commercial motor vehicle in commerce and need a CDL, and to their employers, whether the carrier is interstate or intrastate. Under 49 CFR 382.103(b), an owner-operator who is the only driver must be in a random testing pool of two or more covered employees, which in practice means joining a consortium. The FMCSA census file does not say who holds a CDL, so ask before you pitch. As of October 28, 2026, 122,643 of the 178,190 active carriers registered since October 1, 2025 reported one power unit or none.

Does the FMCSA carrier file show whether a carrier has a BOC-3 or UCR on file?

No. The census file shows the USDOT number, MC docket, contact details, operation, for-hire status, power units, drivers, hazmat and cargo. It does not show BOC-3 status, UCR status, insurance, the date authority was granted, inspections or crash history. An MC, MX or FF docket means the carrier filed for authority, not that the authority is active.

What are the UCR fees for 2027?

From the UCR Plan's fee page, per carrier or freight forwarder: $55 for 0 to 2 vehicles, $167 for 3 to 5, $333 for 6 to 20, $1,163 for 21 to 100, $5,548 for 101 to 1,000 and $54,165 for 1,001 or more. Brokers and leasing companies pay $55. The 2027 fees took effect October 1, 2026, and registration is due before January 1, 2027. They are about 20 percent above the 2026 fees, which started at $46.

When is a carrier's MCS-150 update due?

Under 49 CFR 390.19T, every 24 months by the last day of a month set by the USDOT number. The last digit gives the month (1 is January, 0 is October) and the next-to-last digit gives the year: odd digits file in odd-numbered years, even digits in even-numbered years. A number ending in 87 files by July 31 in even years. Missing it can bring civil penalties and deactivation of the USDOT number.

When does the new entrant safety audit happen?

49 CFR 385.307 puts a new interstate carrier under 18 months of monitoring and calls for a safety audit once it has enough records, generally after at least 3 months. 49 U.S.C. 31144(g) requires the review within 12 months after a property carrier begins operations, and within 120 days for a passenger carrier. Any one of 16 violations listed in 385.321, five of them from the drug and alcohol rules, fails the audit automatically.

Can a compliance mailer mention FMCSA or cite federal rules?

It can, with care. 39 U.S.C. 3001(h) makes a solicitation nonmailable if it reasonably could be read as implying a federal connection through a seal, an agency name or a citation to a federal statute, unless it carries the notice that the offer is not approved by or made by the federal government and the envelope says it is not a government document. The FTC's 16 CFR 461.2 bars falsely posing as or implying affiliation with a government entity. Say you are private in the first lines. This is not legal advice.

Is the new carrier data free?

Yes. The FMCSA Company Census File is free on data.transportation.gov (dataset az4n-8mr2) with no login, and you can filter it by add date, status and state through the URL. A prepared file saves the repeat work of querying, cleaning and decoding it each week. Lead Mining Company sells one at $99 a month for every state (up to 25,000 rows a month) or $149 once for carriers registered in the last 90 days.
