U.S. driver license validation rules
There is no single national driver license number format in the US: AAMVA standardizes the card's fields, but leaves the number's structure up to each state, so this generator encodes 51 separate patterns and validates each one with its own regex.
The H isn't drawn from the letter alphabet, it's a fixed literal in the pattern: every Hawaii number starts with H, so a validator that accepts any letter in the first slot would wrongly accept a state that shouldn't match this pattern at all.
Even though Washington's real algorithm derives part of the number from the holder's name and date of birth, this output is just a 12-position alphanumeric string, with no link to the synthetic profile it's paired with.
1 letter plus 14 digits adds up to 15 characters, against California's 8; a validator written with only California in mind treats this length as an error instead of another state's legitimate format.
No. Each state DMV issues its own licenses with its own number pattern; this tool models one canonical pattern per state.
No. AAMVA standardizes the physical card's fields (name, date of birth, class, restrictions) through the DL/ID standard, but leaves the number's structure entirely up to each of the 50 states plus the District of Columbia; that's 51 distinct formats, each with its own length and mix of letters and digits.
Not in this generator: each position in the pattern (letter, digit or fixed character) is drawn independently, with no checksum tying them together. Validation here is purely about format, length and per-position composition, through a regex built from that same state definition block, not an arithmetic check-digit calculation.
Because each state's definition block is a free sequence of tokens, not a fixed letter-first layout: Iowa is 'D3 L2 D4', 3 digits, then 2 letters, then 4 more digits, while most letter-bearing states, like California, put the letter only up front. The parser reads the tokens in the exact order they appear in the definition.
Because those three uppercase letters look too much like the digits 1 and 0 in many fonts and in handwriting, a real misreading risk in a data-entry field or OCR pass; the alphabet used has 23 letters, A through Z minus I, O and Q, the same exclusion real identification systems commonly apply for that reason.
Expected pattern for this state: 1 letter + 7 digits.
