Vehicle registration plates of Pennsylvania

The U.S. state of Pennsylvania first issued vehicle registration plates in 1906. Until 1979, the embossed date or sticker on the plate represented the date of issue, as opposed to the rest of North America, where it represented the date of expiration. Currently in Pennsylvania, only rear license plates are used for all types except press photographer and official use.

In 1956, the U.S. states and Canadian provinces came to an agreement with the Automobile Manufacturers Association that fixed the size for license plates for vehicles, except those for motorcycles, at six inches in height by twelve inches in width, with standardized mounting holes. The 1955 (dated 1956) issue was the first Pennsylvania license plate that complied with these standards.

Only plates issued since 1999 are currently eligible for display.
