USDOT Number Registration Services

Many commercial carriers are required to obtain a USDOT Number before operating. A USDOT Number is used by the FMCSA to identify carriers, track safety information, and maintain regulatory records. Carrier Compliance HQ helps owner-operators and small carriers complete the registration process through a guided filing experience and ongoing compliance support.

Whether you are starting a new trucking business or determining if federal registration requirements apply to your operation, we help simplify the process and organize what comes next.

The basics

What Is a USDOT Number?

A USDOT Number is a unique identifier assigned by the Federal Motor Carrier Safety Administration (FMCSA). The number allows the FMCSA to monitor safety information, inspections, audits, crash investigations, and compliance activity associated with commercial carriers.

Many carriers operating commercial vehicles in interstate commerce are required to obtain a USDOT Number before beginning operations. It is the foundation of your federal compliance record—most other filings, from operating authority to the MCS-150 biennial update, connect back to it.

A USDOT Number identifies a carrier. It is not the same thing as MC Authority.
