The U.S. state of New York first issued license plates in 1910. Plates are issued by the New York State Department of Motor Vehicles.
In 1956, the U.S. states and Canadian provinces came to an agreement with the Automobile Manufacturers Association that standardized 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 1956 issue (dated 1957) was the first New York license plate that complied with these standards.
