MCS-150 biennial update

Update your carrier registration (MCS-150) every two years — or within 30 days of any material change.

What you'll need

1
Sign in through Login.gov
FMCSA retired its legacy portals (URS, the FMCSA Portal, and USDOT-PIN sign-in) on May 14, 2026. Registration now runs through the new Motus system, which signs in with Login.gov — create and identity-verify a Login.gov account first if you don't have one.
2
Link your carrier record in Motus
First time in Motus, claim your existing USDOT record so it's connected to your Login.gov identity. Follow the current instructions on FMCSA's registration page — the exact screens are still being refined during the transition.
3
Open your biennial update (MCS-150)
Choose the update/biennial-update option for your USDOT number.
4
Verify your details
Confirm legal name, DBA, address, EIN, and company officials are correct.
5
Enter mileage and fleet
Report last year's total mileage and your current number of trucks and drivers.
6
Certify and submit
Review, e-sign, submit, and save the confirmation.

Letting the MCS-150 lapse can deactivate your USDOT and put you out of service. (During the mid-2026 Motus transition FMCSA has paused some automated deactivations — don't count on the pause; file on schedule.)
Also file within 30 days of any change to address, name, or fleet size.
If Motus errors out — a common complaint during the transition — document your attempt (screenshots + date) and retry; check FMCSA's registration page for current guidance.

Fact-checked June 2026. Fees, screens, and dates change — always reconfirm at the official source at filing time.
