Maryland · sequential passenger map
Maryland license-plate format
Maryland’s passenger serial is a leading digit, two letters, 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 67,600,000 — the size of the sequential space taught here. Hyphens, spaces and dots in 9AA9999 are display only.
Maryland’s shield plates moved from ABC 1234 into a leading-digit series as ABC 1234 neared exhaustion.
Before this map, Maryland used ABC 1234 shield plates. Optional graphics (universities, military, environmental) can look nothing like the sequential passenger die and are not counted in the 67,600,000 figure.
SPR9932 lacks the leading digit Maryland now expects.
Generated versus issued
A string that fits 9AA9999 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.
