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
