How do I find my MCS-150 PIN?
Last reviewed October 27, 2026
FMCSA no longer uses a USDOT PIN. Since Motus opened on May 19, 2026 (legacy systems were retired May 14), you sign in with Login.gov and link your USDOT number to your account.
The PIN was a legacy credential from FMCSA's older registration systems. FMCSA retired it with its legacy registration systems on May 14, 2026; the Motus registration system (motus.dot.gov) opened on May 19, 2026. There is nothing to find, recover, or request.
To file an MCS-150 online, create a Login.gov account, sign in at motus.dot.gov, and link your USDOT number to your account. Once the USDOT number is linked, you can review your registration and submit the MCS-150 update in Motus.
If you are trying to get into your FMCSA account, the same steps apply: there is no PIN to look up or replace. Your Login.gov sign-in at motus.dot.gov, with your USDOT number linked to it, is how you get into your FMCSA registration record.
If your business address or contact details are out of date, you correct them in the same MCS-150 update in Motus.
If you would rather not set up Login.gov yourself, a filing service can help: the MCS-150 is prepared and submitted for you. FastMCS150 charges $25 only if you need Login.gov setup help.
