FMCSA requires an MCS-150 update every two years or it deactivates your USDOT number. We file it on your behalf and track your next due date.
Not sure when yours is due? Check the free carrier lookup on the homepage.
The MCS-150 is the form FMCSA uses to keep your USDOT registration information current: your fleet size, mileage, cargo, and operating details. It's a biennial update, not a one-time filing.
Every two years, on a schedule tied to your USDOT number's own digits, not your original registration date. Miss it and FMCSA deactivates your number.
Use the free carrier lookup on the permits.agency homepage. It checks your USDOT number against FMCSA's own biennial schedule. This service also tracks your next due date once you file with us.
