The U.S. state of Wyoming first required its residents to register their motor vehicles and display license plates in 1913.

As of 2024[update], plates are issued and regulated by the Wyoming Department of Transportation through its Motor Vehicle Services division.

Wyoming license plates have included an image of a Bucking Horse and Rider since 1936.

Wyoming state law usually requires front and rear license plates.

[1] 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.
