- Online: If your USDOT number is active, you can begin the online update process.
- By email: You can upload asigned MCS-150 to our web form; you will then receive a tracking number by email. Detailed instructions for this process are attached to this FAQ.
- By mail: Once you have completed the MCS-150 form, you must print the completed form and mail it to the address indicated on the form
- By fax: you can fax your signed form to 202-366-3477 or 606-330-3802
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.
