What the FMCSA census file says about a USDOT number
Type in a number and you see the record: carrier name, registration status, the MCS-150 date on file, and the filing date that number is assigned. Free, no account, no email.
What this does not tell you
This page shows you a copy of a government census record and the filing date arithmetic that goes with the number. It is not a compliance determination. FMCSA makes those. A carrier can be current on the record and still have things going on that never appear in the census, and a stale date can turn out to be a data gap rather than a missed filing.
If the question you actually have is whether a carrier is authorized to haul right now, FMCSA's SAFER lookup answers that one for free.
Checking more than one
SAFER handles one number per search and so does this page. If you have an approved carrier list, the list check takes the whole thing at once and hands back only the records with a stale or missing date.
Read every result on this site with this in mind
FMCSA moved carrier registration to a new system called Motus on 19 May 2026, and MCS-150 filing stopped working for many carriers. On 24 June 2026 Overdrive reported that FMCSA had suspended deactivating USDOT numbers for carriers unable to complete their biennial updates since 1 June 2026.
Two things follow. A record that looks past due may belong to a carrier who tried to file and could not. And the deactivation the regulation describes is not currently being applied. Treat a stale date as a reason to ask the carrier, not as a conclusion about them.
