BOC-3 Process Agent: What It Means, What a Blanket Agent Is, and How to Switch Companies

Reviewed by Austin Park, founder of ICR Filings · Updated October 28, 2026

"BOC-3 meaning" and "BOC-3 process agent" are two of the fastest growing trucking searches this month. Most carriers file a BOC-3 once, when they apply for authority, and do not think about who their process agent is until something goes wrong. Here is what the term means, what a blanket agent is, and how to switch companies safely.

What a process agent is

"Service of process" means formally delivering court papers, like a lawsuit, to a business. A process agent is the person or company in a state who accepts those papers for you and passes them on. The BOC-3, FMCSA's Designation of Agents for Service of Process, is the form that names your agents. FMCSA will not activate operating authority without one on file.

The rules agents must meet

• In-state: each agent must live in or keep an office in the state it is named for (49 CFR 366.3T). A post office box is not an acceptable agent address.
• Every state you need: a motor carrier needs an agent in each state it is authorized to operate in and each state it passes through (366.4T). Brokers need one in each state where they have offices or write contracts.
• One form at a time: only one completed BOC-3 can be on file, and it must cover every required state (366.2T).
• Keep a copy at your principal place of business.

Blanket agents: why most carriers use one

Finding your own agent in every state would be a project. Instead, a blanket agent (an association or company that has filed a list of process agents for every state with FMCSA) covers all of them in one filing. Under 49 CFR 366.5T, the carrier's BOC-3 simply designates the agents on that company's list, including future updates to it. Ours covers all 50 states and DC.

When to switch process agent companies

• Your company sent a yearly bill you did not expect, or raised its price
• You cannot reach it, or it closed
• It cancelled your filing, or you got a suspension notice about your BOC-3
• Your legal name or ownership changed and you need a new filing anyway

How to switch without a gap

1. 1
   Check who is on file now

   Search your MC or USDOT number in FMCSA's L&I public search. Your BOC-3 history shows the company that filed it.
2. 2
   File the new BOC-3 first

   A process agent company files it for you with your exact legal name, address, and docket number. It replaces the old designation.
3. 3
   Confirm it posted

   Check L&I again in a business day or two. The new company should show on your BOC-3.
4. 4
   Then end the old relationship

   Only after the new filing shows, cancel or stop paying the old company.

Keep your agent up to date

When your name, address, phone, or email changes, tell your process agent company. If someone serves papers on your agent, the agent has to be able to reach you, and a lawsuit you never hear about can turn into a default judgment. If your legal name changed, you need a new BOC-3 (see changing your company name or address).
