Q. MC Numbers for Motor Carriers
In addition to getting a DOT number, you need to apply for an MC number to operate as a "for-hire" carrier in interstate commerce, or to become a broker.
To get operating authority you must complete the appropriate motor carrier operating authority forms (OP-1 series) and submit them to FMCSA for processing. Please read the instructions for the appropriate OP-series form carefully to avoid errors.
