Carrier authority lookup

Look up a motor carrier by USDOT number to see what is on file with the FMCSA: legal name, physical state, self-reported fleet size band, and the date the record was captured. This covers the largest active carriers by fleet size and reports public federal registration data only. It is not a safety rating and not a substitute for verifying authority and insurance before you dispatch anyone.

5,000 carriers. the 5000 carriers with the most self-reported power units, excluding records above the sanity ceiling.

This record was captured from the FMCSA Motor Carrier Census on 2026-08-07. It reflects what was on file with the FMCSA on that date and not necessarily the carrier's situation today.

Fleet size and driver counts are self-reported by the carrier to the FMCSA and are updated on the carrier's own filing schedule. They are an indication of scale rather than a current count of equipment.

This page reports public federal registration data. It is not a safety rating, not a recommendation, and not a substitute for verifying authority and insurance before dispatching a carrier.

The FMCSA census is refreshed on the agency's own schedule, so a very recently registered carrier or a very recent change may not appear here yet.
