What a USDOT lookup shows

Each record includes the legal and DBA name, physical and mailing address, USDOT status (active/inactive), operating authority status, carrier operation type (interstate/intrastate), power units and drivers, cargo carried, safety rating, and company officers - sourced from official FMCSA / SAFER data and refreshed continuously.

USDOT number vs. MC number

A USDOT number identifies the carrier for safety and registration; an MC (motor carrier / docket) number represents operating authority to haul regulated freight for hire across state lines. Many carriers have both. You can search dotsearch.us by either - see the MC number lookup for MC-specific searches.
