DOT numbers: Interstate commercial vehicles

Starting January 1, 2023, vehicle registrations allow the removal of your address. New registrations have your address located on the bottom. There's a dotted line showing where to cut it. This is optional and intended to provide address privacy in case of theft.

If you operate a commercial vehicle across state lines, you must have a United States Department of Transportation (USDOT) number.

How to apply for a DOT number

To get a USDOT number, submit the following completed forms to the Federal Motor Carrier Safety Administration (FMCSA):

  • Motor Carrier Identification Report (MCS-150).
  • Safety Certification Application (MCS-150A).
