MCS-150 Filing Services
Your USDOT registration has to be updated with FMCSA every two years — even if nothing changed — or your number is deactivated and your operating authority stops. We file your MCS-150 biennial update on time, handle initial registration and changes, and keep your USDOT record current and active.
The MCS-150 is the biennial USDOT registration update every carrier must file every two years to keep its USDOT number active. We file it — plus initial registration and reactivations — for you.
Every motor carrier with a USDOT number has to update its registration with FMCSA on a two-year cycle by filing the MCS-150 — and it's required even when nothing has changed. Miss it, and FMCSA deactivates your USDOT number, which stops your operating authority and can leave you unable to run.
We file it — on schedule
We track your biennial update deadline, set by your USDOT number, and file the MCS-150 on time so your registration never lapses. We also handle initial registration, mid-cycle updates when your address, fleet size, or operation changes, and reactivation if a number has gone inactive.
One less deadline to miss
Your USDOT record stays current and active, and you don't have to remember the cycle or navigate the FMCSA portal — we do.

Compliance Requirements
Compliance Requirement
The biennial update — required even with no changes
FMCSA requires every carrier with a USDOT number to update its MCS-150 registration at least every 24 months, on a schedule based on the USDOT number. The update is required even if none of your information has changed.
Consequences of missing it
A carrier that fails to file its biennial update has its USDOT number deactivated, which suspends operating authority and can result in penalties.
When else to file
The MCS-150 is also filed for initial registration, when key information changes, and to reactivate a deactivated number.

We pull and review motor vehicle records from every state a driver has been licensed — at hire and annually, as DOT requires — flag disqualifying offenses, and file the review in the driver's qualification file. $20 per driver plus state fees at cost.
