What is a BOC-3, and who is allowed to file it?
It is the least glamorous filing in interstate trucking and one of the few that can switch a USDOT number off. Here is what it designates, who may submit it, and the honest limit of what a lookup can confirm about it.
The honest limit here
The BOC-3 is not a field in the datasets this site reads, so no page here will claim to show you one. What the record gives you is indirect and still useful: operating authority cannot be granted or stay active without a designation on file, so the authority lines are the nearest evidence — and where the answer stops, this site says so rather than inferring.
The short answer
Form BOC-3, Designation of Agents for Service of Process, names the person in each state who may be handed court or agency papers on the company’s behalf. A process agent must reside in, or keep an office in, the state they are designated for (49 CFR 366.3, read 2026-09-03).
It exists so that someone with a claim against a motor carrier, broker or freight forwarder in a state that company merely drives through has somebody local to serve. It is a mailbox for lawsuits, and nothing more romantic than that.
Which states have to be covered
Under 49 CFR 366.4 the coverage follows the operation rather than the address:
- Motor carriers designate for all 48 contiguous states and the District of Columbia, unless the operating authority registration is limited to fewer — in which case, for each state authorised plus each state traversed.
- Brokers and freight forwarders designate for each state, including DC, where their offices are located or where contracts will be written.
- Alaska and Hawaii — a company with its principal place of business there and operating exclusively there designates for that state alone.
Why a blanket agent is the normal answer
Naming an individual agent in forty-nine jurisdictions is not how this is done in practice. 49 CFR 366.5 allows an association or corporation to file a list of agents covering every state and DC — a blanket agent — after which a company designates them all in one sentence, with room to name an individual agent for particular states as an exception.
That is why the BOC-3 market looks the way it does: a small number of blanket agents, a flat one-off fee, and a filing done in minutes.
Only a process agent can file it
This is the part that trips people. The designation is submitted to FMCSA by the process agent, on behalf of the applicant — the company cannot file its own BOC-3, which is why every search for the form leads to services rather than to a download.
Only one completed current form may be on file, it must cover every state the designation is required for, and the company keeps a copy at its principal place of business (49 CFR 366.2). Changing agents means a new complete designation, not an amendment to the old one.
The consequence of not having one
A designation is due at the time of the registration application, and 49 CFR 366.2(b) provides that failure to file one results in deactivation of the USDOT number. Operating authority does not issue without it either — the administrative filings have to be complete before FMCSA activates a number under 390.205.
So the BOC-3 sits underneath authority as a precondition. That is what makes the record readable on this point without publishing the form itself: authority that is active is authority whose administrative filings were accepted. It is inference, it is one step removed, and it is stated that way on purpose.
Questions
Can I file my own BOC-3? +
No. FMCSA accepts the designation from a process agent filing on behalf of the applicant, not from the company itself. This is the single most common misunderstanding about the form and the reason the search results are all services.
Does a BOC-3 expire? +
It does not run on a renewal clock the way the biennial update does. One current form stays on file until it is replaced — but changing process agents, or gaining authority in states the designation does not cover, means a new complete filing.
Do I need one if I operate only within my own state? +
The requirement in 49 CFR part 366 attaches to interstate operating authority. Purely intrastate operation is a matter for the state, and this site does not track state registration schemes — the state agency is the right place to ask.
How much does a BOC-3 cost? +
FMCSA charges nothing for the designation. The fee you pay is the process agent’s, it is generally a modest one-off, and it is charged for standing as your agent in every state rather than for the paperwork.
Can I see a company’s BOC-3 in a lookup here? +
No, and no page on this site will pretend otherwise. The designation is not in the datasets this site reads. What you can see is the authority it is a precondition for, which is a weaker signal honestly labelled.
