- The FMCSA regulates federal for-hire operating authority, which is a requirement along with the USDOT number.
Federal for-hire operating authority is regulated by the Federal Motor Carrier Safety Administration (FMCSA). This authority is required in addition to and separate from a USDOT number.
For-hire authority is issued after the entity submits an authority application, provides proof of financial responsibility, and provides a list of agents that can accept legal paperwork on behalf of the motor carrier in each state in which the carrier operates.
A company may need multiple for-hire authorities for its operations. Each type of authority will indicate the type of operations an entity can run and the cargo it may carry.
Interstate for-hire motor carriers are issued a motor carrier (MC) number. The MC number is issued with interstate operating authority and is necessary before conducting interstate for-hire motor carriage. The MC number is no longer displayed on the vehicle. According to 49 CFR 390.21, carriers must have, or obtain and display on the vehicle, a USDOT number and their legal company name before beginning operations.
Eventually, the FMCSA will no longer issue MC numbers. The USDOT number will be the carrier’s sole identifier. The effective date for this change will be determined by the FMCSA later.
