The BOC-3 form: the filing your authority waits on
FMCSA won't grant operating authority until your process agents are on file. The BOC-3 that names them takes about 10 minutes to complete, by FMCSA's own estimate, yet a wrong detail or a lapsed agent can keep your trucks parked.

The BOC-3 in numbers
A BOC-3 is the FMCSA form that names a process agent in each state where you operate, so legal papers can be served on your company. For-hire carriers, brokers, and freight forwarders need one on file before FMCSA grants operating authority, and a motor carrier's BOC-3 must be filed by its process agent.
A new carrier earns nothing until its authority is active, and the BOC-3 is one of the filings that decides when that happens. It is also one of the smallest filings in the process, which is exactly why it gets rushed.
I have spent more than 22 years at Simplex, nearly 16 of them as COO, and I judge every step of launching a carrier by what it does to the day you can start hauling. This guide covers what the BOC-3 is, who can file it, what it must cover, and how to keep it from becoming the reason your trucks sit.

Key takeaways
No BOC-3, no active authority
FMCSA requires a process agent designation on file before it grants operating authority to a carrier, broker, or freight forwarder.
Carriers can't file their own
Only a process agent can file the BOC-3 for a motor carrier. Brokers and freight forwarders without trucks may file for themselves.
Cover every state you run
A carrier with nationwide authority needs an agent in each of the 48 contiguous states, which is why most use a blanket company.
It has to stay valid
If your agent relationship ends, FMCSA can give you 30 days to file a new BOC-3 before it suspends your authority.
Motus didn't change the BOC-3, yet
FMCSA moved registration to Motus in May 2026 (legacy tools closed May 14; Motus opened to all registrants May 19), but left the BOC-3 filing process and MC numbers as they were for now.

What is a BOC-3 form?
A BOC-3 is the form FMCSA uses to record your designation of agents for service of process: the people in each state who can accept court papers on your company's behalf. Federal law requires carriers and brokers to name one in each state where they operate, and the rules sit in 49 CFR Part 366.
Three rules shape the filing. Only one completed BOC-3 can be on file at a time, it must include every state where you need an agent, and you keep a copy at your principal place of business (49 CFR 366.2T).
Who needs a BOC-3?
- For-hire motor carriers applying for operating authority (an MC number)
- Property brokers
- Freight forwarders
Private carriers hauling their own goods don't have to file one yet. FMCSA says that changes only once all of the Unified Registration System rules take effect, and those rules remain suspended.
If you are still working out which registrations your company needs, our guide to starting a trucking company puts the BOC-3 in the full sequence.
Which states must your BOC-3 cover?
A motor carrier must name an agent in each state it is authorized to operate in and each state it passes through (49 CFR 366.4T). Because operating authority is nationwide, FMCSA's policy is that a carrier running in the lower 48 needs an agent in each of the 48 contiguous states.
| Who | Where you need an agent |
|---|---|
| Motor carrier running in the lower 48 | Each of the 48 contiguous states |
| Carrier operating only in Alaska or Hawaii | That state only |
| Mexico-domiciled carrier in a commercial zone | Only the states it operates in |
| Broker | Each state where it has an office or writes contracts |
The Alaska, Hawaii, and commercial zone rows come from FMCSA's process agent FAQ.
What is a blanket designation?
Few companies have people in 48 states, so most use a blanket company: a business that has filed a list of process agents for every state with FMCSA. Your BOC-3 then designates everyone on that list (49 CFR 366.5T). As of September 24, 2026, FMCSA lists 75 registered blanket companies.
Each agent must live in or keep an office in the state they cover (49 CFR 366.3T), and a post office box is not acceptable as an agent's address. You may name yourself for the state where you live, but you still need agents everywhere else.
Who can file a BOC-3?
For a motor carrier, only a process agent can file the BOC-3 with FMCSA, on the carrier's behalf. A broker or freight forwarder that doesn't operate commercial motor vehicles can file its own.
So if you run trucks, you can't file your own BOC-3. You choose the agent, and the agent submits the filing. FMCSA's registration fee schedule has no line for the BOC-3; blanket companies charge for their service.
Brokers who self-file take on the agent's job themselves: an agent in each state where they have an office or write contracts, and a single current form that covers all of them.
How does the BOC-3 activate your operating authority?
Your operating authority is granted only after two filings reach FMCSA: your BOC-3 and your proof of financial responsibility. FMCSA's policy states that a designation of process agent must be on file before a carrier, broker, or freight forwarder receives operating authority registration.
Step 1: Apply in Motus
New applicants now apply for a USDOT number and operating authority in Motus, FMCSA's registration system. Our guide to FMCSA's Motus system covers identity verification and account setup.
Step 2: Choose a process agent
Pick a blanket company from FMCSA's list and give it your legal name, USDOT number, and docket number as they appear on your FMCSA record. Our trucking authority packages include the process agent.
Step 3: The agent files your BOC-3
The agent submits the designation to FMCSA for you. The rule text in effect, 49 CFR 365.109T, asks for it within 20 days of your application notice appearing in the FMCSA Register.
Step 4: Get your insurance or bond filed
Carriers need their insurer to file Form BMC-91 or BMC-91X. Brokers need a BMC-84 surety bond or a BMC-85 trust fund agreement. These filings come to FMCSA from your insurer, surety, or financial institution, so budget for what commercial truck insurance costs before you apply.
Step 5: Keep a copy and check your record
Keep a copy of the BOC-3 at your principal place of business, and confirm the designation shows on your FMCSA record. UCR is a separate annual registration, not one of the filings the grant waits on; our UCR guide covers it.
Active authority is also not permanent authority. It becomes permanent only after you complete FMCSA's New Entrant Safety Assurance Program (49 CFR 365.110).
What happens if your BOC-3 lapses?
FMCSA can suspend your operating authority. Under its 2019 policy, a carrier, broker, or freight forwarder must keep a valid process agent designation at all times for its authority to stay active.
It usually starts when the agent relationship ends: a blanket company drops a client, goes out of business, or refuses service. FMCSA can then issue an Order to Show Cause, and you have 30 days from service to file a new BOC-3 with a valid agent or show that the one on file is valid. Miss that, and FMCSA may issue a final suspension order.
Two details make this a revenue risk, not just paperwork. FMCSA generally sends its orders to your mailing address and to your BOC-3 agent, so an agent who can't reach you is a gap in your notice. And a designation can be changed only by filing a new one (49 CFR 366.6T), so switching agents means a new BOC-3.
There is no annual renewal: your BOC-3 stays on file until a new one replaces it. Your USDOT record is different, and has its own MCS-150 biennial update schedule.
Did Motus change the BOC-3?
Not yet. FMCSA closed its legacy registration tools on May 14, 2026, and opened Motus to all registrants on May 19, and blanket companies now submit and remove BOC-3 filings there. Who needs a BOC-3, who may file it, and what it must cover are unchanged.
In an April 29, 2026 Federal Register notice, FMCSA said stakeholders had raised concerns about three planned changes: a new safety registration, eliminating MC and FF docket numbers, and changes to how the BOC-3 is filed. The Motus launch left all three out, and FMCSA said it would phase them in later.
The same notice said FMCSA expected to propose a rule in spring 2026 requiring Motus for all registrants and eliminating the paper registration forms, the BOC-3 among them. As of September 24, 2026, that proposal has not appeared in the Federal Register, so the Part 366 rules above still apply.
