Wisconsin · sequential passenger map
Wisconsin license-plate format
Wisconsin passenger plates use three letters, a hyphen, and four digits. In this atlas the pattern string uses A for a letter slot and 9 for a digit slot. Other characters are separators that appear on the metal but do not enlarge the combination space.

How the map works
Each A slot independently takes one glyph from ABCDEFGHIJKLMNOPQRSTUVWXYZ. Each 9 slot takes 0–9. The product of those bases is 175,760,000 — the size of the sequential space taught here. Hyphens, spaces and dots in AAA-9999 are display only.
America’s Dairyland plates adopted ABC-1234 early relative to some neighbours. Graphic colours changed; the hyphenated serial stayed the sequential passenger standard.
Before this map, Wisconsin used ABC-123 and America’s Dairyland stacks. Optional graphics (universities, military, environmental) can look nothing like the sequential passenger die and are not counted in the 175,760,000 figure.
SPR-9932 is in-class as a generated combination.
Generated versus issued
A string that fits AAA-9999 is in-class. It is not automatically an issued plate. Series can skip blocks, retire numbers, or reserve low digits. This essay never queries a motor-vehicle file. See also generated vs issued.
