DOT Number
A unique identification number assigned by the US Department of Transportation to every commercial motor carrier, freight broker, and freight forwarder operating in interstate commerce. The DOT number is used to track a company's safety record, compliance reviews, crash data, and inspection results. It must be displayed on both sides of every commercial vehicle the carrier operates.
Real-World Example
A shipper verifies a carrier's DOT number 1234567 on the FMCSA SAFER website and confirms the carrier has a satisfactory safety rating, current insurance, and no out-of-service orders.
