Connecticut · sequential passenger map
Connecticut license-plate format
Connecticut’s standard passenger serial is two letters, a hyphen, and five 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 AA-99999 are display only.
New England’s dense fleets forced Connecticut off all-numeric plates. Two letters plus five digits yields a large space without a seven-letter vanity look.
Before this map, Connecticut used 123-456 and early letter suffixes. Optional graphics (universities, military, environmental) can look nothing like the sequential passenger die and are not counted in the 67,600,000 figure.
Low-digit all-numeric plates still exist as reissues; they are outside this passenger-serial model.
Generated versus issued
A string that fits AA-99999 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.
