To activate your MC number, you are required to file a BOC-3 form with the Federal Motor Carrier Safety Administration (FMCSA).

The BOC-3 form contains a list of agents who will receive legal or official documents on your behalf and forward them to you. If you are an Interstate Motor Carrier, you are required to have a designated agent in each state.

Filing your BOC-3 form will register you in all 50 states.
