Transporting businesses in Oklahoma, particularly those involved with trucking and passenger carriers for hire services, are required to obtain various licenses through the Oklahoma Corporation Commission (OCC). If the operations involve travel solely within the state, then, only Intra-state licensing and issuance of a USDOT number through OCC will be required.

If travel of a transporting business is across state lines, a registration (which will include the issuance of a USDOT number) will be required from the Federal Motor Carriers Safety Administration (FMCSA).
