FMCSA public records · updated daily
Check a carrier's authority before the load moves
One USDOT or MC number in, the federal record out: operating authority, insurance on file, fleet size — with the date it was read stamped on it.

Stamped with a date
Every record carries the snapshot date it was read from FMCSA. A screenshot with no date proves nothing six months later; a dated record does.
Facts, no scores
Authority status, insurance on file, fleet size — reproduced as published. No rating, no grade, no opinion about who you should book.
Same data over JSON
The page and the API return the identical carrier card. One GET, no SOAP, no scraping, no key needed to try it.
A carrier you cleared in March can lose its authority in July.
Nobody sends you a letter. Watch a carrier and the daily pass tells you when the record moves — authority, insurance, legal name, address.

The carrier card, one GET away
If you build a TMS, a dispatch board or an agent that touches carriers, you shouldn't have to scrape SAFER or parse a federal ZIP file. The same JSON that renders the page above is the API — no SOAP envelope, no session, no key to try it.
Monitoring ships with it: watch a carrier and a daily pass reports authority, insurance, name and address changes — by webhook or by polling a change log.

}Common questions
What is a USDOT number? +
A USDOT number is the identifier FMCSA assigns to a company that operates commercial vehicles in interstate commerce. It stays with the company and is the key every federal record is filed under.
What is the difference between a USDOT number and an MC number? +
The USDOT number identifies the company and its safety record. The MC (motor carrier) docket number is the operating authority that permits it to haul regulated freight for hire across state lines. Many carriers hold both; a carrier hauling only exempt commodities or operating intrastate may hold just a USDOT number.
Where does this data come from? +
From the FMCSA public datasets published on data.transportation.gov — the census file, the carrier authority file with history, and the insurance file with history. Nothing here is scraped and nothing is user-submitted.
How current is it? +
FMCSA republishes those datasets daily, and every response is stamped with the date it was read. Filings can take days to appear in the federal record after they happen, which is exactly why the snapshot date is on every card.
Is this free? +
Looking up carriers on the site is free. The JSON API is free to try at 100 lookups a day; a key lifts the cap for production use.
