BOC-3

Definition

BOC-3 is the FMCSA form that designates process agents in every state where an interstate motor carrier, broker, or freight forwarder operates. Required under 49 USC §13304 and 49 CFR Part 366. FMCSA won't grant operating authority until a BOC-3 is on file. Most carriers use a single blanket BOC-3 filed by a process-agent company, so one filing covers every required state. The filing is one-time; refile only on legal-name change or to switch agents. The federal BOC-3 is unrelated to a state-level registered agent, which the LLC also needs.
