What is an MC Number?
An MC number (Motor Carrier number) is a unique identifier assigned by the Federal Motor Carrier Safety Administration (FMCSA) to for-hire carriers operating in interstate commerce. While a DOT number is required for all commercial vehicles, an MC number is specifically required for carriers that transport regulated commodities for compensation across state lines.
