The 1956 (dated 1957) issue was the first Illinois license plate that fully complied with these standards: the 1955 (dated 1956) issue was 6 inches in height by 12 inches in width, but had non-standard mounting holes. 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. The 1954 plates were the first to feature the "Land of Lincoln" slogan, which continues to be used today. License plates were placed under the jurisdiction of the Secretary of State in 1953. The state reverted to manufacturing its plates from steel in 1949, although the 19 plates were instead manufactured from aluminum. This practice continued each year up to and including 1948, despite the war ending in 1945 with the surrender of Japan.

With the entry of the United States into World War II, and the subsequent introduction of measures to conserve metal for the war effort, Illinois manufactured its license plates for 1943 from wood-based fiberboard instead of steel. In 1927, the state issued its first graphic license plate, featuring an embossed state shape to the right of the serial. Trailers received their own plates from 1924 onwards. Serials on these plates were all-numeric until 1930, when weight codes were introduced. Trucks received their own plates for the first time in 1920. Aluminum dashboard discs were discontinued after 1917. Six-digit all-numeric serials were introduced in 1916, followed in 1925 by seven-digit serials. When 99999 was reached in 19, serials with one letter and four digits were issued.

Serials were all-numeric and originally ran to five digits.

The legislation authorizing the state issuance of license plates also provided for the registration and plating of motorcycles, and issued special licenses and plates to mechanics and chauffeurs. Front and rear plates were required each year, along with an aluminum dashboard disc whose number matched the serial on the plate. The state began to issue license plates in 1911. Registrants were issued a numbered aluminum disc to place on their dashboard, but they had to provide their own license plates. Automobile owners in Illinois were first required to register their vehicles with the Secretary of State's office in 1907, paying a one-time registration fee of $2.
