It is critical that motor carriers, brokers, and other registered entities log in to the FMCSA Portal by May 14, 2026, to ensure their Portal accounts are up to date. Failure to take these steps may result in existing registrants being unable to claim their USDOT Number in Motus once the system goes live. Please read an example of the letter that will be mailed out.

Log in to their FMCSA Portal account to ensure it is active.
Verify their Portal Company Official. Learn how.
Submit an online Biennial Update (MCS-150) in the Portal “Registration” tab.
