List of trucking companies: the largest carriers, the DOT records behind all 2.1 million, and how to build your own list

This guide is for companies that sell to trucking companies: insurance agencies, factoring and fuel card providers, telematics and fleet software, truck and trailer dealers, maintenance and tire shops, and driver recruiters. It also helps shippers checking carriers and drivers comparing employers. It explains how many trucking companies there are, which are largest, what the federal DOT records contain, and how to turn them into a usable list.

How many trucking companies there are

Two federal sources count trucking companies, and they measure different things.

FMCSA's registry counts every company with an active USDOT number: anyone operating commercial vehicles in interstate commerce, plus some intrastate carriers. As of its 25 September 2026 snapshot, it listed these carriers in the 50 states and DC:

For-hire interstate carriers also need operating authority (an MC number). FMCSA counted 315,567 active property carrier authorities and 23,792 broker authorities, with that data current as of 15 May 2026.

County Business Patterns, the Census Bureau's count of business locations with paid employees, found 170,286 truck transportation establishments in 2023, employing 1,693,228 people.

The gap between 2.1 million and 170,286 is the point. FMCSA's file includes owner-operators with no employees, plumbers and builders with private fleets, and registrations that are active on paper but rarely used. Census leaves out the self-employed and counts only trucking businesses with staff, and 123,520 of those (72.5%) still have fewer than five employees. Most of the market is very small.

The largest trucking companies

Transport Topics ranks for-hire carriers by annual revenue. Its 2026 Top 100 (2025 revenue) starts:

These are a few dozen accounts out of two million, and they buy through procurement with long qualification cycles. For 3PLs, freight brokers and warehouses, see the list of top third party logistics companies.

Union and out-of-business trucking companies

Union carriers. The Teamsters represent drivers at several of the largest carriers. UPS Teamsters ratified a five-year contract in August 2023 covering more than 340,000 workers through 2028, and ABF Freight's Teamster-represented employees ratified a new five-year national master freight agreement in 2023. Union carriers buy differently: work rules, seniority and grievance procedures shape how new equipment and software get rolled out.

Closed carriers. Yellow Corporation, an LTL carrier founded in 1924, filed for Chapter 11 on 6 August 2023 to wind down its operations, with about 30,000 jobs lost. For any carrier, FMCSA's Licensing and Insurance system shows whether its authority is active, revoked or reinstated, and the Company Census File marks registrations as active or inactive. Check both before you contact a carrier on an old list.

What the DOT records contain

Federal rules require every registered carrier to update its registration every 24 months, on a schedule set by the last two digits of its USDOT number. A record that hasn't been updated in more than two years is a warning sign: the carrier may have stopped operating.

How trucking companies buy

Drivers matter at every size. A product drivers hate (an app that slows them down, a fuel card that's refused at stops) gets dropped. Insurance renewal is the biggest annual purchase for small fleets and a natural moment to review other vendors.

Segment the list

• For-hire or private. A private fleet at a food distributor buys differently from a for-hire carrier.
• Fleet size. Power units in the Census File; CBP size bands for territory sizing.
• Operation. Truckload, LTL, flatbed, tanker, refrigerated, hazmat, intermodal drayage. The Census File lists cargo types.
• Interstate or intrastate. Interstate for-hire carriers need operating authority; intrastate carriers follow their state's rules.
• Recent change. New authority in the last 90 days, a jump in power units, a new address, or a safety event.

Outreach angles and timing

New carriers are the most obvious lead: the FMCSA Register lists new authority applications and grants by date, and insurers and factoring companies watch it closely. Stand out by being specific. A growing fleet (power units up since the last update), a new terminal, or an inspection trend in SMS each gives you a dated, factual opener. Call early in the morning or late afternoon, when owners and dispatchers are at a desk rather than on the road. Pulling the records, finding the right owner or safety manager and researching each carrier is the slow part at volume; Bebop finds matching companies and contacts and writes a playbook for each account.

Worked example: small fleets in Texas

Illustrative example. The seller and its plan are fictional; the Texas counts come from FMCSA's September 2026 registration statistics and County Business Patterns 2023.

The seller: Gearlog (gearlog.example) sells maintenance software to fleets of 10 to 50 trucks. The territory: Texas, which FMCSA says has 180,551 active carriers, 129,381 of them for-hire only.

1. Size it. County Business Patterns counts 14,177 trucking establishments in Texas, and 2,254 of them have 10 to 49 employees: a better guide to the number of real 10 to 50 truck fleets than FMCSA's total.
2. Pull the names. Download the Company Census File, keep Texas for-hire carriers with 10 to 50 power units, and drop any record not updated in the last 24 months.
3. Prioritize. Rank carriers whose power units grew since their previous update, or with a recent maintenance-related inspection violation in SMS.
4. Do the arithmetic. Contact 300 carriers in a quarter. At an illustrative 8% reply rate, that's 24 conversations; if an illustrative quarter of those start a trial, 6 trials.
5. Write to the fleet. Lead with what you saw in the record:

Subject: [company]'s fleet since [month]

Hi [first name],

I saw [company] has grown to [number] power units in your latest DOT update. Congratulations.

Most fleets your size tell us the same thing happens around 20 trucks: maintenance moves from memory and a whiteboard to missed PMs and surprise roadside violations.

We help fleets of 10 to 50 trucks [outcome, e.g. schedule PMs by mileage automatically]. Worth 15 minutes this week?

Common mistakes

• Treating every USDOT number as a trucking company. Many are private fleets of other businesses or idle registrations.
• Ignoring the update date. Records older than 24 months are often dead.
• Buying a directory with no DOT numbers. You can't check status, size or safety without one.
• Pitching a 500-truck fleet like an owner-operator. Size changes who decides and what they care about.
• Calling mid-day. Owners and dispatchers are busiest when trucks are moving.

Next step: set your fleet size, operation and region with the ideal customer profile template, then pull the Company Census File records that match it.
