Michigan · sequential passenger map
Michigan license-plate format
Michigan passenger plates use three letters, a space, 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.
Michigan’s Great Lakes plates needed a four-digit tail as the fleet grew. AAA 9999 is the sequential passenger map used in this atlas.
Before this map, Michigan used ABC 1233 and Great Lakes graphics. Optional graphics (universities, military, environmental) can look nothing like the sequential passenger die and are not counted in the 175,760,000 figure.

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.
