Louisiana · sequential passenger map
Louisiana license-plate format
Louisiana passenger plates use three letters, a space, and three 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 17,576,000 — the size of the sequential space taught here. Hyphens, spaces and dots in AAA 999 are display only.
Parish names still appear on many Louisiana graphics, but the passenger serial taught here is the three-by-three block.
Before this map, Louisiana used ABC 123 pelican stacks with parish names. Optional graphics (universities, military, environmental) can look nothing like the sequential passenger die and are not counted in the 17,576,000 figure.
SPR 9932 has four digits, so it overshoots Louisiana’s three-digit tail.
Generated versus issued
A string that fits AAA 999 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.
