# Vehicle registration plates of Guam

The U.S. unincorporated territory of Guam first required its residents to register their motor vehicles and display license plates in 1916.
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. Guam adopted these standards in 1960.
