Can two companies share one BOC-3 filing?
No - two companies cannot share one BOC-3.A BOC-3 designates a process agent for a single operating authority, keyed to that company's MC docket and USDOT number in FMCSA's records under 49 CFR Part 366. The filing cannot “cover” a second docket, so each legal entity that holds its own FMCSA authority needs its own BOC-3 - even when two companies share the same owner, address, office, and process-agent service. The practical answer for multi-entity operators: a single registered process-agent provider can service all of your entities on one account, but it files one BOC-3 per MC number. File a BOC-3 for $75 per authority, and your dockets each carry the designation FMCSA requires.
Why the BOC-3 is one-per-docket, not one-per-owner
The reason comes down to what the BOC-3 actually identifies. It is not tied to a person, a brand, or a yard - it is tied to a specific MC docket so that, if someone needs to serve legal papers on that authority, there is a named agent and physical street address on file for it. Two companies are two authorities, so they need two designations.
| Scenario | How many BOC-3s? | Why |
|---|---|---|
| Two MCs, same owner, same address | 2 | Two dockets = two designations (49 CFR §366.4) |
| Parent company + subsidiary, each with authority | 2 | Each legal entity holds its own MC docket |
| One company, carrier and broker authority | 2 | Separate registrations, usually separate dockets |
| One company, one MC, two trucks | 1 | One docket - the BOC-3 covers the authority, not units |
| One MC operating in all 50 states | 1 | A single blanket filing covers all states for that docket |
Sources: 49 CFR Part 366 (process-agent designation, per authority); 49 CFR §366.4 (who must designate); 49 CFR §366.5 (form content); 49 USC §13304 (statutory designation requirement).
Common ownership doesn't merge two dockets
This trips up a lot of growing operators. You set up a second LLC for tax or liability reasons, you run it from the same office, the same owner signs everything - it feels like one operation. But the moment that second entity registers with FMCSA and receives its own MC and USDOT number, it is a separate authority in the eyes of 49 CFR Part 366, and it must independently satisfy the process-agent requirement. The same logic applies to the insurance filing: each docket needs its own BMC-91 proof of financial responsibility under 49 CFR Part 387. One company's compliance never “flows through” to the other just because they share a parking lot.
One provider, multiple filings: the clean setup
The good news is that “separate BOC-3s” does not mean separate vendors or separate headaches. A single registered blanket process-agent company can service every entity you own under one account and file a distinct BOC-3 for each MC docket. That keeps your renewals, your point of contact, and your billing in one place while still giving each authority its own legally clean designation. Motor carriers operating commercial motor vehicles must use a registered provider like this - they cannot self-designate. (The lone exception: a broker or forwarder running no CMVs may designate itself in its home state under 49 CFR §366.4(b).) If you are weighing how broad each filing needs to be, our breakdown of single-state vs. blanket process agents explains why most multi-state carriers default to blanket coverage for every docket.
Reorganizing entities? The BOC-3 doesn't transfer
When operators consolidate - closing one LLC and moving the trucks under another - a frequent assumption is that the surviving company can inherit the closed company's BOC-3. It cannot. The designation is bound to the docket it was filed under, and a new authority needs a fresh BOC-3 of its own. The only thing that stays with the same docket is a change of process agent: if you keep the same MC and simply switch to a different agent, that is a re-designation on the existing authority, not a transfer between companies. See how to switch your process agent for that path, and our pillar guide on whether you need a BOC-3 for the underlying rules. New owner-operators standing up a first authority should start at BOC-3 for owner-operators.
How to verify each entity is actually covered
Because each docket is filed separately, you should confirm the BOC-3 is on file for every MC you run - it is easy to file for the first company and forget the second. The process-agent record lives in FMCSA's Licensing & Insurance (L&I) system rather than SAFER, so look up each MC number there to see its current designation. Our process-agent overview and the step-by-step how to file a BOC-3 walk through filing and confirming each one. Treat it as a per-docket checklist: every authority you hold needs its own BOC-3, its own insurance filing, and its own confirmation.
Frequently asked questions
- Can two companies use the same BOC-3 filing?
- No. A BOC-3 designates a process agent for one specific operating authority, identified by its MC docket and USDOT number in FMCSA records under 49 CFR Part 366. The filing is keyed to that single docket, so it cannot legally "cover" a second company. Two companies that each hold FMCSA authority must each have their own BOC-3 on file - even if they share an owner, an address, and the same process-agent service.
- I own two trucking companies with the same address - do I really need two BOC-3s?
- Yes. Common ownership and a shared address do not merge two MC dockets into one. Each separate legal entity that registers with FMCSA receives its own MC number and must independently satisfy the process-agent requirement under 49 CFR §366.4 and the insurance requirement under 49 CFR Part 387. You can put both entities with the same process-agent provider on a single billing account, but a distinct BOC-3 is lodged for each MC number.
- My carrier also brokers freight under a separate authority - one BOC-3 or two?
- Two. Carrier authority and broker authority are separate registrations, usually under separate MC dockets, so each needs its own BOC-3. There is a wrinkle for the broker side: a broker or freight forwarder that operates no commercial motor vehicles may designate itself as its own process agent in its home state under 49 CFR §366.4(b), while the carrier side running CMVs must use a registered blanket process-agent company. Most owners simply put both dockets with one provider and let it file a BOC-3 per authority.
- Can one process-agent company handle the BOC-3 for both of my entities?
- Yes - and that is the normal setup. A single registered blanket process-agent provider can service any number of your entities under one account, filing one BOC-3 per MC docket. What it cannot do is staple two dockets onto a single filing. Think of it as one vendor, two (or more) filings - each BOC-3 names the agent for one authority so that service of legal process under 49 USC §13304 is unambiguous for each company.
- If I close one company and move the trucks to the other, can I reuse its BOC-3?
- No. A BOC-3 is not transferable between MC numbers. When operations move to a different legal entity and authority, that receiving entity needs its own BOC-3 tied to its own docket. If you are instead keeping the same MC and only changing your process agent, that is a switch on the same docket, not a transfer - see how to switch your process agent rather than re-filing under a new company.
