What is a USDOT Number?

The Federal Motor Carrier Safety Administration (FMCSA) requires all businesses to obtain a USDOT number prior to starting a commercial transportation business. A USDOT number (DOT number) is a unique identification number that allows for instant access to a company’s safety information. This number helps to provide information during inspections, audits, accident investigations, compliance reviews, etc. and must be displayed on every vehicle. The FMCSA DOT number provides the foundation for any other registration that you may need.

Do I Need DOT Authority?

FMCSA DOT numbers are required in specific states for certain business types. A DOT number is required for the following:

  • Retains a gross vehicle weight, combination weight, vehicle weight rating, or gross combination weight rating, of 4,536 kg (10,001 pounds) whichever is greater.
  • It is constructed or used to transport more than 8 passengers (driver included) for compensation.
  • It is constructed or used to transport more than 15 passengers, drivers included, and not used to transport passengers for compensation.
