MC Number (Motor Carrier Number)
An operating authority number issued by FMCSA that authorizes a company to transport regulated commodities for hire in interstate commerce. While the DOT number identifies the company, the MC number grants the legal authority to operate as a for-hire carrier or freight broker. Obtaining an MC number requires filing an application, meeting insurance requirements, and paying a filing fee. New authorities typically take 3 to 6 weeks to become active.
