MC Number (Motor Carrier Number)

An operating authority number required for carriers engaged in interstate commerce.

Definition

A Motor Carrier (MC) number is an identifier assigned by FMCSA to carriers and brokers operating in interstate commerce. There are different types: MC for carriers, FF for freight forwarders, and MX for Mexican carriers. Obtaining MC authority involves registering with FMCSA, obtaining insurance ($750,000 minimum for general freight), filing a BOC-3 process agent designation, and paying a filing fee. The entire process takes 4-6 weeks.

Why it matters to you

The MC number is the authority that lets you haul other people's freight for money across state lines. Getting one means insurance filings, a process agent and a probationary safety period, and new authority is treated warily by brokers for the first months. Anyone telling you it is a quick route to independence is skipping the part where you have to be creditworthy and insurable.
