Arizona · sequential passenger map
Arizona license-plate format
Arizona’s standard passenger serial is three letters followed by four digits with no separator. 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 AAA9999 are display only.
Arizona cycled through county prefixes and desert graphics. The seven-character AAA9999 block expanded capacity without a dash, which is why SPR9932-style strings are analysed here without a hyphen.
Before this map, Arizona used AAA-NNN and cactus graphic series. Optional graphics (universities, military, environmental) can look nothing like the sequential passenger die and are not counted in the 175,760,000 figure.
Vanity plates in Arizona can break this pattern entirely; this atlas only models the standard passenger serial.
Generated versus issued
A string that fits AAA9999 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.
