Q. Cancelling DOT Number

How do I cancel a DOT number? 


In order to cancel an existing DOT number, you will need to file form MCS-150. You may download this form and find other instructions at http://www.fmcsa.dot.gov/registration/updating-your-registration.

While there is a phone number and other contact information on the site, the general steps are as follows:

1: Download form MCS-150 to your computer. The FMCSA download forms site is listed in References. Print all nine pages of the form, which includes instructions. This is a multipurpose form used for registration as well as inactivating your US DOT number. Read these instructions well.

The form and the website strongly urge companies to submit this form for registration or acquiring a US DOT number online. Take time to read all three Web pages listed to understand more about the process.

2: Complete items 1 through 16 and 30. At the top of the form MCS-150, mark the reason for the report. Place a mark next to the selection that states "Out of business notification."

3: Read and follow the instructions for item 30 exactly. Print or type the name and title of the person authorized to sign documents on behalf of the company listed in item 1. This person must sign and date the form in the spaces provided in item 30. Follow the instructions to the letter because if the signature does not match the printed or typed name, the form will be rejected.

4: Make a copy of your completed form to keep in your records and then mail the original MCS-150 form to:

Federal Motor Carrier Safety Administration
Attention: USDOT Number Application
1200 New Jersey Avenue SE
Washington, DC 20590

If you do have any further questions, please contact FMCSA directing at the contact information listed on http://www.fmcsa.dot.gov/registration/updating-your-registration.
