USDOT, MC, BOC-3 & UCR: Step by Step

Apply for a USDOT number and MC authority together in FMCSA's Unified Registration System, have your insurer file proof of coverage, have a process agent file your BOC-3, register for UCR, and your authority activates once filings are on file.

Steps in order

1. URS application: fmcsa.dot.gov/registration. $300 per type of authority (FMCSA).
2. Insurance filing: your insurer files proof with FMCSA (minimums in 387.9).
3. BOC-3: a process agent files designations for each state (Part 366).
4. Protest period: the application is published; authority is granted once filings are complete.
5. UCR: register at plan.ucr.gov before operating.
6. Check status in our lookup or on SAFER.

Keep it active

• Update your MCS-150 every two years (390.201).
• Renew UCR each year.
• Never let insurance or BOC-3 lapse: missing filings can lead to revocation.

Scam warning

Expect many solicitations once your application is public. Official fees are paid to FMCSA and UCR directly; private 'compliance' offers are optional. Back to the authority guide.
