What is operating authority?
Operating authority is federal FMCSA registration - commonly called an MC number or MC authority - that every for-hire motor carrier, freight broker, and freight forwarder is required to obtain under 49 USC §13902 before hauling or brokering freight across state lines. The FMCSA issues a unique MC number that shows in FMCSA’s records (Motus public search) once the authority is active. Until then, a carrier’s USDOT record shows it as not authorized for for-hire interstate work.
