A Motor Carrier (MC) number and a Department of Transportation (DOT) number are unique identifiers assigned to commercial motor carriers. These numbers are essential for companies operating vehicles in interstate commerce, transporting passengers, or hauling cargo. Obtaining these numbers involves registering with the Federal Motor Carrier Safety Administration (FMCSA) and meeting specific regulatory requirements. For example, a trucking company that transports goods across state lines is required to secure both an MC and a DOT number.
These identifiers play a critical role in ensuring safety and compliance within the transportation industry. They allow the FMCSA to track a company’s safety record, including crashes, inspections, and compliance reviews. Having these numbers enables legitimate businesses to operate legally, build credibility with customers, and access opportunities for growth. Historically, the implementation of these identification systems has enhanced oversight and contributed to a safer operating environment for all stakeholders.
