MC and DOT Numbers – What Every Trucker Needs to Know

If you’re starting a trucking company or expanding your operations, one of the first steps to staying legal on the road is securing your MC (Motor Carrier) Number and USDOT Number. These numbers are more than just identifiers—they are essential for compliance with federal regulations and prove that your business is authorized to operate.

At Affordable Trucker Help, we help trucking businesses in Atlanta, Suwanee, Savannah, Macon, Augusta, across Georgia, and nationwide understand what these numbers mean, why they matter, and how to stay compliant.

What is a DOT Number?

A USDOT Number is issued by the Federal Motor Carrier Safety Administration (FMCSA) and serves as a unique identifier for your trucking company. It is used to track your safety record, inspections, compliance reviews, and accident reports.

If you operate a commercial vehicle that weighs more than 10,000 pounds, transports hazardous materials, or crosses state lines with freight, you are required to have a USDOT Number.

Learn more directly from the FMCSA USDOT Number overview.

What is an MC Number?

An MC Number (Motor Carrier Number) is also issued by the FMCSA and is required if your trucking company operates as a for-hire carrier transporting regulated commodities in interstate commerce. This number grants your business operating authority and confirms that you are properly insured and registered.

In other words, while a USDOT Number identifies your trucking company, an MC Number authorizes your trucking operations. Many carriers need both numbers to stay fully compliant.

See more details on the FMCSA Operating Authority page.

Why MC and DOT Numbers Matter

Having the correct MC and DOT Numbers ensures that your trucking business is recognized by federal regulators, shippers, and brokers. Without them, you cannot legally operate in interstate commerce. Here’s why they’re important:

• Legal Compliance – Required by law for most commercial trucking companies.
• Shipper & Broker Trust – Many customers won’t hire carriers without valid MC and DOT Numbers.
• Safety Monitoring – DOT Numbers track your company’s compliance and safety history.
• Insurance Verification – FMCSA uses your MC Number to confirm you carry proper liability insurance.
