USDOT Number
A unique federal identifier issued by FMCSA to commercial motor carriers operating in interstate commerce.
A USDOT Number is the unique identifier FMCSA issues to commercial motor carriers, intermodal equipment providers, freight forwarders, brokers, and shippers operating in interstate commerce or transporting hazmat in intrastate commerce.
The DOT Number is used to track the carrier's safety record, audits, inspections, crashes, and compliance. It's required on both sides of the truck cab.
An MC Number (Motor Carrier number, or 'authority') is separate — it's required for for-hire carriers and brokers, and grants permission to operate in interstate commerce. Many small carriers will have both a DOT and an MC.
