To update the company’s Legal/DBA name or phone number associated with your USDOT Number record, you can use one of the following options. Updating your USDOT Number record is free of charge. 

Option 1: Online Update

Complete the process online using your USDOT PIN. You can find detailed instructions for the online process attached to this FAQ.

Option 2: Submit a Form

Download the appropriate MCS-150 form: MCS-150 (Motor Carriers), MCS-150B (Motor Carriers with HazMat Permit), or MCS-150C (Intermodal Equipment Providers). Once completed and signed, submit the form using one of the options below:

• Submit a ticket through our website at ask.fmcsa.dot.gov (scroll to the bottom of the page, complete the required fields, and upload your documents). This is the fastest option, and you will receive a confirmation number by email.
• Fax the form to 202-366-3477 or 606-330-3802.
• Mail the form using the instructions provided on the form. Please note that this option may result in a delay in processing, and we recommend using one of the first two options.

In some cases, a legal name change, ownership change, or change in form of business may require a new USDOT number. For more information on this, click here.

Please note that if you change the name associated with your USDOT number, it will not automatically update your MC number. You will need to go through the MC number name change procedure separately. However, if you change the name associated with your MC number, it will also be updated for your USDOT number. There is a $14 fee for an MC number name change.
