USDot number

Official standing public browser lookup for FMCSA Licensing & Insurance records by USDOT number, docket number, legal/DBA name, and state or country. Carrier details document identity, addresses, operating-authority status and history, public regulatory insurance filings and compliance, BOC-3 compliance, pending applications, and revocations. No developer schema is offered, so Feature paths, wire types, and cardinalities remain unknown.

Its Socrata API and reusable full-file export expose the current 147-column MCMIS row schema covering entity identity, operations, equipment, drivers, cargo, addresses, docket identifiers, and review/safety fields. Equipment fields are carrier-reported owned, term-leased, or trip-leased fleet counts, not VIN or title ownership.
