The U.S. state of Oklahoma first required its residents to register their motor vehicles and display license plates in 1915. As of 2023, plates are issued by Service Oklahoma. Only rear plates have been required since 1944.

Prior to July 1, 2019, plates belonged to the car, not the owner. As a result of lost turnpike toll revenue and law enforcement having trouble tracking vehicle owners, the law was changed, meaning plates now belong to vehicle owners and can be transferred from a previous vehicle to a new vehicle.^[1]

Passenger baseplates

1915 to 1978

In 1956, the United States, Canada, and Mexico came to an agreement with the American Association of Motor Vehicle Administrators, the Automobile Manufacturers Association and the National Safety Council that standardized the size for license plates for vehicles (except those for motorcycles) at 6 inches (15 cm) in height by 12 inches (30 cm) in width, with standardized mounting holes.^[2] The 1955 (dated 1956) issue was the first Oklahoma license plate that complied with these standards.
