How can I reactivate my USDOT number?

To reactivate a USDOT number, you will need to mail or fax a completed and updated MCS-150 form. You can only submit it online if:

  • You are reactivating a US DOT number that was deactivated due to failure to complete the Biennial Update: You must check the box “Biennial Update or Changes” in the “Reason for Filing” section
  • You are reapplying after a New Entrant Revocation: You must check the box “Reapplication (after Revocation of New Entrant)” in the “Reason for Filing” section

If you are a Mexico-domiciled carrier or your number has been deactivated for reasons other than not filing your Biennial Update, then you will need to mail or fax a completed and updated MCS-150 form. You must check the box “Biennial Update or Changes” in the “Reason for Filing” section.

You can submit the paper form in one of two ways:

  • Mail: You can send the updated MCS-150 form to:
    Federal Motor Carrier Safety Administration
    Office of Registration and Safety Information (MC-RS) 
    Licensing Team, 6th Floor
    Washington, D.C. 20590
  • Fax: You can fax the MCS-150 form to: 703-280-4003

If you have questions regarding a revoked or deactivated status on your USDOT number, please call 800-832-5660.
