What is a USDOT Number?

Companies that operate commercial vehicles transporting passengers or hauling cargo in interstate commerce must be registered with the FMCSA and must have a USDOT Number. Also, commercial intrastate hazardous materials carriers who haul types and quantities requiring a safety permit must register for a USDOT Number.

The USDOT Number serves as a unique identifier when collecting and monitoring a company's safety information acquired during audits, compliance reviews, crash investigations, and inspections.
