BOC-3
Also known as: Designation of Process Agents
By Korey Sharp-Paar · Reviewed by the Fast Trucking Compliance team
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. Without an active BOC-3 on file, MC authority cannot activate — the docket stays in NOT AUTHORIZED status indefinitely. Most carriers file a single blanket BOC-3 covering all 50 states plus DC through a process-agent service for around $75. 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.
