BOC-3 Filing

Last reviewed September 27, 2026 by Korey Sharp-Paar · Founder, FastBOC3 Filing

Form BOC-3 is the FMCSA filing that names a process agent for every state where you operate or travel (49 CFR 366.2T, 366.4T). For motor carriers it must be filed by a process agent, usually a blanket company. Brokers and freight forwarders without trucks may file their own. Only one BOC-3 can be on file.

  • FMCSA titles it "Designation of Agents for Service of Process"; the rule is 49 CFR Part 366.
  • It carries your legal name, principal address, USDOT and MC/FF/MX numbers, and an agent for each required state.
  • FMCSA publishes the form PDF, but a motor carrier's BOC-3 must be filed by a process agent.
  • Brokers and freight forwarders without trucks may file their own, per FMCSA's Form BOC-3 page.
  • Only one BOC-3 is on file at a time; a new one replaces the old designation (366.6T).

People search “BOC-3 form” expecting a PDF with boxes to fill in. FMCSA does publish the form, but for a trucking company the form is something a process agent files for you, not something you mail in. This guide covers what the form is, what is on it, who may file it, and how to check yours. If you need one filed, our BOC-3 filing service handles it for $75 once.

What Form BOC-3 is

FMCSA titles it Form BOC-3, Designation of Agents for Service of Process. It names a process agent (someone who accepts court papers for you) in each state where you are required to have one. The rule behind it is 49 CFR Part 366: designations are made on Form BOC-3, only one current form may be on file, and it must list every required state (366.2T). Motor carriers cover every state they are authorized to operate in and every state they travel through; brokers cover the states where they have offices or write contracts (366.4T). For the meaning of the formal name, see designation of process agents.

Form BOC-3 vs. “a BOC-3 filing”

Form BOC-3 is the document: the designation record naming your business and your process agents. A BOC-3 filingis getting that document onto your FMCSA record. When a company sells you “a BOC-3,” you are paying for the filing and for the process agent that stays named on it, not for a blank form.

What's on the form, field by field

The form has two parts: who you are, and who your agent is in each state. In plain terms:

Form BOC-3 information, summarized. Check FMCSA's form for the exact field wording.
InformationWhat to know
Legal business nameExactly as registered with FMCSA, including LLC or Inc. A DBA alone won't match.
Principal business addressYour principal place of business, where a copy of the BOC-3 is kept (366.2T).
USDOT number and MC, FF or MX numberTies the designation to your authority record.
Process agent, for each required stateThe agent's name and street address, city, state and ZIP. The agent must reside in or keep an office in that state (366.3T), and FMCSA doesn't accept a P.O. box. With a blanket company, one statement naming the company designates its whole list (366.5T).

Is there a BOC-3 PDF?

Yes. FMCSA publishes the form PDF and its instructions on its Form BOC-3 page. Use that page as your source; copies on PDF-editing sites can be out of date.

What the PDF is for depends on who you are. For a motor carrier, filling in the PDF isn't the route: FMCSA says a motor carrier's BOC-3 must be filed by a process agent. A broker or freight forwarder that doesn't operate trucks may file its own, and the PDF is where it starts (steps below).

Who files Form BOC-3

  • Motor carriers: a process agent files it, usually a blanket company that has its own list of agents for every state on file with FMCSA (49 CFR 366.5T).
  • Brokers and freight forwarders without trucks: may file their own, per FMCSA's Form BOC-3 page, or use a blanket company. See can I file my own BOC-3?

Only one BOC-3 can be on file, and a new one replaces the old designation (49 CFR 366.6T). When you order from FastBOC3, your BOC-3 is filed by a registered blanket process-agent company on FMCSA's list, which is the agent named on your form.

Motor carriers: what your process agent will ask you for

You don't fill in the form yourself. Expect to provide:

  • Your legal business name, exactly as on your FMCSA registration.
  • Your USDOT number and MC (or MX) number.
  • Your principal business address.
  • An email and phone number, so served court papers and the filed copy can reach you.

The agent completes the per-state designations. File as soon as your MC number is assigned: new applicants must have the BOC-3 on file within 20 days of the FMCSA Register notice (49 CFR 365.109T).

Brokers and freight forwarders: filing your own BOC-3

  1. Confirm you operate no trucks. The self-filing option on FMCSA's form page is for brokers and freight forwarders only.
  2. Get the current form and instructions from FMCSA's Form BOC-3 page.
  3. List every required state: each state where you have an office or where contracts will be written (49 CFR 366.4T).
  4. Name an eligible agent for each of those states: someone who lives in or has an office in that state (49 CFR 366.3T), at a street address, not a P.O. box.
  5. Submit it the way FMCSA's form page instructs.
  6. Keep a copy at your principal place of business (366.2T), and check your Motus record afterwards.

How to check and keep your BOC-3

Your process agent sends you a copy of the filed BOC-3; keep it, because the rule asks you to keep one at your principal place of business. To see what's on your record, look up your USDOT number or legal name in FMCSA's Motus public search (no login needed), which shows the process agent (BOC-3) details under your operating authority; it usually shows within about one business day of filing, and FMCSA controls that timing. Details: how to check your BOC-3 status and how to find your process agent.

Common BOC-3 form mistakes

  • A legal name that doesn't match your FMCSA record, such as a DBA or a missing “LLC”.
  • An agent address that is a P.O. box or not in the state being covered.
  • A second BOC-3 filed by a dispatcher or setup company that replaces yours.

Frequently Asked Questions

What is a BOC-3 form?

Form BOC-3 is the FMCSA form titled "Designation of Agents for Service of Process." It names a process agent, someone who accepts court papers for your business, in every state where you are required to have one under 49 CFR Part 366.

Is there a BOC-3 PDF?

Yes, FMCSA publishes the form and its instructions on its Form BOC-3 page. A motor carrier doesn't use it to file, though: FMCSA requires a process agent to file a motor carrier's BOC-3, while brokers and freight forwarders without trucks may file their own.

What information is on a BOC-3 form?

Your legal business name, principal business address, and USDOT and MC, FF or MX numbers, plus a process agent with a street address for each required state. The agent must live in or keep an office in the state it covers, and a P.O. box is not accepted.

Who fills out and files the BOC-3 form?

For a motor carrier, a process agent, usually a blanket company, completes and files it. A broker or freight forwarder that operates no trucks may file its own BOC-3, as FMCSA's Form BOC-3 page allows.

Can more than one BOC-3 be on file?

No. Only one current BOC-3 can be on file (49 CFR 366.2T), and a new filing replaces the earlier designation (49 CFR 366.6T).

How do I get a copy of my BOC-3 form?

Your process agent sends you a copy after filing, and you should keep it at your principal place of business (49 CFR 366.2T). You can also see the BOC-3 and the agent named in FMCSA's Motus record under your USDOT number.
