Multi-year plates validated by metal tabs were introduced in 1942. Due to WWII metal rationing concerns, the production of full-size plates was suspended from late 1942 to late 1943. In the meantime, small motorcycle-size plates with three or four letters and numbers in various configurations were issued to passenger vehicles.
The highest numeric serial confirmed on the 1942 base is 771 626.

After 1945, Wisconsin became the first state to stagger registrations between all twelve months of the year. Motorists received a new plate expiring anywhere from June 1946 to May 1947. "46"-dated plates were distributed only for codes from "6" to "12," while "47"-dated plates only encompassed codes "1" through "5." Subsequent new registrations received undated baseplates.

Numerous base, die, and stamping variations may be found on these plates. A fair number of motorists ordered replacement plates during this six-year timespan, so later plates with lower numbers and mismatched pairs abound:
Original 1946 plate (at)9
Ca. 1951 remake of same number (at)9

In 1952, the license plate format was changed to implement a stamped month abbreviation and alpha serial prefix. Alpha prefixes were keyed to the month of expiration, and through 1960 a two-letter format was employed if a given month series overran its initial allocation. A series of two-year bases (or three-year, in the case of the 1965 issue) followed. Adhesive stickers replaced metal tabs in 1961 (coinciding with 1962 expirations), although tab slots were retained on the baseplates themselves through 1963.
