USDOT Number Search
Search by USDOT number to open a carrier's full profile — registration status, safety history, and operating authority, built from public FMCSA data.
This is the same identifier FMCSA's own SAFER system uses — 'USDOT number' and 'DOT number' refer to the same thing.
USDOT number vs. DOT number
These are the same identifier — "USDOT number" and "DOT number" are used interchangeably in the industry and by FMCSA itself. Both refer to the number assigned when a company first registers with the Federal Motor Carrier Safety Administration. It's distinct from an MC (Motor Carrier) number, which relates specifically to for-hire operating authority — see our MC to DOT converter for how the two relate.
Why search by USDOT number
A USDOT number search is the most reliable way to verify a specific carrier, because the number is unique and permanent — company names change, merge, or get reused, but the USDOT number doesn't. If you're a broker or shipper vetting a carrier before booking a load, or a driver checking a potential employer, searching by USDOT number avoids the ambiguity of a name search matching the wrong company.
What the search returns
A CarrierPedia carrier profile brings together five separate FMCSA datasets: the registration record (Company Census), safety performance (SMS BASICs), crash history, inspection and out-of-service results, and operating authority with insurance status — all under one USDOT number, with a percentile comparison against other active carriers so a raw number like "12 crashes" has context. See Data Sources for exactly where each figure comes from.
MCS-150 filing status
Every active carrier is required to update its MCS-150 form with FMCSA every two years — this is the same form that populates the Company Census dataset our profiles are built from. A carrier profile shows the date of the most recent MCS-150 filing, and flags it as outdated if it's more than 24 months old, since that can indicate a lapse that puts the registration at risk of deactivation.
