How to File a BOC-3: Process Agents for New Carriers

Last updated: October 21, 2026 · Sources: FMCSA Form BOC-3 page (updated July 16, 2026), 49 CFR Part 366

Quick answer: A BOC-3 names a process agent (someone who can accept legal papers for your company) in every state where you operate. A motor carrier can't file it; a process agent files it for you, usually a "blanket" company that covers every state in one filing. FMCSA needs it on file, along with insurance, before your authority can be granted.

Step by step

Pick a process agent. Most new carriers use a blanket company. FMCSA publishes a list of blanket companies on its process agents page. Prices vary by provider. Check the web address before you pay.
Give them your exact legal name, USDOT and docket number. Match your FMCSA record exactly; mismatches delay filings.
The agent files the BOC-3 with FMCSA for you. Only a process agent can file for a motor carrier (FMCSA).
Check that it posted. Look up your company on FMCSA Licensing & Insurance. Filings can take a few business days to show.
Keep a copy at your principal place of business, as FMCSA requires.

Switching process agents

Since only one BOC-3 can be on file, the new filing replaces the old one. Make sure the new filing shows on Licensing & Insurance before you cancel the old provider, so you're never without a designation.

Common mistakes

Using a P.O. box for a self-designated agent.
Name or address mismatches between the BOC-3, the insurance filing and your FMCSA record.
