Delaware · sequential passenger map
Delaware license-plate format
Delaware is famous for low-number numeric plates; the atlas models a six-digit passenger serial. 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 1,000,000 — the size of the sequential space taught here. Hyphens, spaces and dots in 999999 are display only.
Delaware never needed a letter block for ordinary passenger issues the way larger states did. Numbers are prestige objects; five- and six-digit strings remain the public serial.
Before this map, Delaware used shorter numeric runs. Optional graphics (universities, military, environmental) can look nothing like the sequential passenger die and are not counted in the 1,000,000 figure.
A lettered string such as SPR 9932 is not a Delaware passenger serial. Numeric neighbours are used instead.
Generated versus issued
A string that fits 999999 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.
