Getting a DOT/MC

Understanding DOT and MC Numbers for Trucking Companies

For trucking companies operating in the United States, obtaining Department of Transportation (DOT) and Motor Carrier (MC) numbers is a crucial step in ensuring legal compliance and the ability to operate interstate. These identifiers are not just numbers; they are key to your business’s ability to function within federal and state regulations.

DOT Number

A DOT number is a unique identifier assigned by the Federal Motor Carrier Safety Administration (FMCSA) to monitor a company’s safety information. It is required for vehicles hauling cargo or passengers across state lines, and in some states, for intrastate operations as well.
