Can I go into my local FMCSA Division office to update my US DOT number?

No, MCS 150 updates must be done either online, fax or by mail:


You can call 800-832-5660 to have an MCS-150 form mailed to you. Once you have completed the form, you can mail it to the address indicated on the form or submit it as indicated above. You cannot make updates verbally over the telephone; a signed form is required.


Biennial updates are processed immediately if done online, but updates filed by email, fax or mail may take three to four weeks to process.
