Short answer
A BOC-3 is the FMCSA form that designates process agents, the people who can accept court papers for a motor carrier, broker, or freight forwarder. Anyone applying for operating authority needs one on file. Carriers must cover each state they operate in or pass through. Brokers must cover each state where they have offices or write contracts.
What the BOC-3 does
FMCSA describes a process agent as a legal representative upon whom court papers may be served in any proceeding against a motor carrier, broker, or freight forwarder. If a trucking company based in Texas is sued in Oregon, the plaintiff can serve its Oregon process agent instead of chasing the company across the country.
The rules live in 49 CFR Part 366, and the designation is made on Form BOC-3.
Which states a BOC-3 must cover
| Registrant | States required |
|---|---|
| Motor carrier | Each state it’s authorized to operate in and each state it travels through |
| Broker | Each state where it has offices or where contracts will be written |
| Carrier operating only in Alaska or Hawaii | That state only |
From 49 CFR 366.4 and FMCSA’s process agent FAQ.
Who files it
FMCSA’s BOC-3 page sets out the filing rules:
- A process agent files the BOC-3 on behalf of a motor carrier.
- A broker or freight forwarder with no commercial motor vehicles can file on its own behalf.
- Designations can be individual or blanket. A blanket designation uses a company that keeps agents on file across states.
- Only one completed BOC-3 can be on file at a time, and it must include every required state.
- A post office box can’t serve as an agent’s address.
- Changes require filing a new BOC-3.
- The carrier or broker keeps a copy at its principal place of business.
The BOC-3 and your authority
The BOC-3 is one of the filings that decides whether authority is granted at all. FMCSA says an application is dismissed when the applicant doesn’t provide proof of insurance and a BOC-3 within about 90 days of filing. For a broker, the insurance side is the $75,000 BMC-84 bond or BMC-85 trust fund. For a carrier, it’s liability coverage, and cargo insurance if it hauls household goods.
FMCSA moved registration to Motus in 2026. During Motus’s limited access period, FMCSA’s modernization FAQ said blanket companies must keep using the FMCSA Portal for BOC-3 filings. Confirm the current filing channel with your process agent.
Example: a new brokerage's filings
Example. A new freight brokerage in Illinois applies for broker authority and receives its USDOT number and MC number.
- The owner arranges a $75,000 surety bond, and the surety files the BMC-84.
- The owner either files a BOC-3 directly, since the brokerage has no trucks, or pays a blanket process agent company to file it. One quote in this example is $50, and prices vary.
- With both filings on record inside the 90-day window, the application can move forward.
The guide to starting a freight brokerage covers the rest of the setup.
Common BOC-3 mistakes
- Waiting on the BOC-3 until the application is dismissed.
- Switching process agent companies without filing a new BOC-3.
- Listing a P.O. box as an agent address.
- A carrier that expands into new states without making sure its designation covers them.
- Keeping no copy of the BOC-3 at the main office.
