What information goes on a BOC-3 form?
Form BOC-3 lists the carrier's legal name, business address, USDOT number, and MC docket number, plus a designated process agent (name, street address, city, state, ZIP) for every state in the U.S. plus the District of Columbia. There are 51 process-agent lines plus the carrier identification block.
The Form BOC-3 carrier-identification block at the top requires four items: the carrier's exact legal name as registered with FMCSA, the carrier's principal place of business, the USDOT number, and the MC docket number. Any mismatch with the FMCSA L&I-system record results in a rejection (covered in the rejection FAQ above). Names must match to the character; an "LLC" missing from the legal name is enough to trigger a rejection.
The 51 process-agent lines (50 states plus D.C.) each require: agent name (individual or company), agent street address (P.O. boxes not accepted — must be a physical address), city, state, ZIP code. The agent named on each line must be a registered process agent under Form BOC-91; the FMCSA L&I system cross-references the BOC-91 registration before accepting the BOC-3.
For a carrier filing through a blanket-coverage provider, the same provider typically appears on every line. The provider has agents physically located in each state under their BOC-91 and the BOC-3 lists the provider's agent in each state. This is the standard pattern and what the §366.4 "blanket of coverage" framework was designed to accommodate.
For state-by-state designations (rare in 2026), each line names a different agent in that state. The carrier files one BOC-3 listing all 51 designations together; partial filings (BOC-3 covering some states only) are not accepted. The form is all-or-nothing per submission.
There is no signature line on Form BOC-3 — the form is filed electronically through the FMCSA L&I system by the registered process-agent provider, and the provider's BOC-91 standing is the digital signature equivalent. Carriers who handle their own filing through self-designation in their home state still need a BOC-91-standing process-agent provider for the other 50 lines.
