If your company transports passengers or goods, you may need a USDOT number. USDOT numbers uniquely identify your business and allow the USDOT to track safety records and ensure that you are adhering to all operating requirements. You can get your motor carrier number online for free from the Federal Motor Carrier Safety Administration (FMCSA).

Navigate to the FMCSA website listed in Resources.

Click on "Register Online" under "Registration & Licensing."


Click on "Start the Step-by-Step Registration Guide."


Fill in the interview style questionnaire. The questionnaire will help you decide if you need a USDOT number and if you do, it will ask your the questions needed to submit the application.


Pay for your motor carrier number and then write it down when you have completed the application. It will be issued immediately.



  • Make sure you put the motor carrier number on all of your eligible vehicles. Driving a commercial vehicle without a USDOT number can result in hefty fines and penalties.
