Trucking companies in St. Louis: a two-state market of movers, car haulers and dedicated fleets

This report is for shippers and plant logistics managers looking for a St. Louis carrier, drivers comparing employers, and B2B sellers whose customers are trucking companies: factoring and insurance firms, repair shops, equipment dealers and software vendors.

A freight crossroads on two banks

The St. Louis Regional Freightway, the freight enterprise of Bi-State Development, markets the region's six Class I railroads, its river port facilities and its interstates. Trucks connect all three, and the interchange of I-64/I-55 with I-44 ranks among the country's worst truck bottlenecks.

St. Louis trucking in Census data

County Business Patterns 2023 covers NAICS 484 (Truck Transportation) in the St. Louis, MO-IL Metro Area (CBSA 41180).

The Census Bureau doesn't publish the two largest size classes for St. Louis. The published classes add up to 1,329, one short of the 1,330 total, so one establishment has 500 or more employees and 34 have 100 or more. That leaves 1,142 with 1 to 19 employees and 154 with 20 to 99.

Movers, specialists and LTL

We derived average pay from payroll and employee counts. Two groups are bigger here than in most metros. Specialized long-distance carriers (car haulers, tankers and other equipment-specific long hauls) average 22.4 employees per site and the best pay. And household movers average 19.5 employees; Mayflower Transit, which lists household goods, is one of the metro's largest registered fleets.

Counties on both banks

The city of St. Louis has the largest sites, 25.2 employees each, and St. Clair County, across the river, averages 20.9. Jefferson County, to the south, is mostly small operators at 3.6 employees per site. Madison and St. Clair counties together hold 216 establishments and 3,889 jobs, 22% of the metro total.

These are establishments with paid staff, not companies. Owner-operators without employees and private fleets aren't included, and a carrier with yards on both sides of the river is counted once for each.

The largest fleets in FMCSA's register

FMCSA's Company Census File, updated 29 October 2026, lists 4,955 active for-hire carriers with at least one truck in the metro's 14 counties and the city of St. Louis. Of these, 3,104 updated their self-reported MCS-150 filing in the past two years: 83% are registered for interstate work, 1,611 (52%) run one power unit and 322 run 11 or more. 490 (16%) report hazardous materials and 539 (17%) list motor vehicles, against 10.5% and 14.6% of current for-hire registrations nationally. Cargo types are self-reported by carriers, and FMCSA's open-data file doesn't always match a carrier's own SAFER record, so treat the motor vehicle share as indicative.

For-hire filings only, ranked by power units as reported; we dropped two large fleets whose driver counts were under a tenth of their power units. Cassens lists motor vehicles as its only cargo, and Mayflower lists household goods. EDGAR shows no listed trucking company based in the metro.

Rules on each side of the river

Interstate for-hire carriers on either bank need a USDOT number, FMCSA operating authority and insurance on file. On the Illinois side, the Illinois Commerce Commission requires a Public Carrier Certificate for anyone engaged in for-hire transportation of property, other than household goods, on Illinois roads in intrastate commerce, and its Motor Carrier Information System search shows whether a carrier holds one. Household goods movers need separate authority. For loads that stay in Missouri, ask the carrier which Missouri credentials it holds; the Missouri Trucking Association in Jefferson City is a starting point for state questions.

Checking a St. Louis carrier

1. Search the USDOT number in FMCSA's SAFER Company Snapshot for size, cargo classes and inspection results.
2. Confirm authority and insurance in FMCSA's Licensing and Insurance system for interstate for-hire work.
3. For an Illinois-only move, check the ICC certificate.
4. For hazmat, steel or vehicles, confirm the cargo class appears on the carrier's FMCSA filing and that the insurance fits the commodity.
5. Ask which yard will serve you. A carrier with Missouri and Illinois yards may dispatch your load from either.

Selling to St. Louis trucking companies

Small fleets buy when cash is tight, which is often when they add a truck or a new broker customer. For a method to build the list, see how to build a prospect list.

Illustrative example. The funder and its terms are invented; the counts are FMCSA register data.

Gateway Freight Funding (gatewayfunding.example) buys carriers' freight invoices and pays within a day, then collects from the shipper or broker. Its list is the metro's 1,171 current for-hire carriers with 2 to 10 power units, which often carry fuel and payroll for weeks before a broker pays. With one contact each (the owner) and a 4% reply rate, that's 47 conversations; if one in four opens an account, 12 carriers. The opener is specific: a carrier that just added a second or third truck has more invoices outstanding than it did a month ago. Bebop can find small fleets like these and research each before you write.

Subject: Getting paid faster at [company]

Hi [first name],

[Company] now runs [number] trucks out of [city]. At that size, a few slow-paying brokers can tie up a month of fuel and payroll.

We buy your invoices the day you deliver and collect from the broker ourselves. No minimum volume, and you choose which loads to send.

Would a quick call on [day] be useful?

[Your name]
