A BOC-3 filing (“Designation of Agents for Service of Process”) is a federal filing in the United States that assigns a process agent to accept legal documents on behalf of a transportation or logistics company in each state in which the company is authorized to do business. FMCSA requires an active BOC3 to maintain an active operating authority.
 
Through BOC-3 filing, you will be assigned a process agent in each state. However, many BOC-3 filing services are available in all states. Through such process agents, you do not need to find a process agent in each state. Instead, you have blanket coverage, which means that you have one process agent available in all states.
