Wyoming PlateFinder Information

In 1930, the state of Wyoming adopted the license plate numbering scheme still in use today: License plates begin with a number in the range 1-23, which identifies the county that issued the plate.
Numbers were assigned based on each county’s total property valuation in 1930.
In 1936, Wyoming license plates began to feature the "Bucking Horse" (believed by some to represent a legendary rodeo horse named "Steamboat"— "the horse that couldn’t be ridden").
