Arizona Driver's License validator
How the Driver's License format works
- Format
- 1 letter followed by 8 digits, or 9 digits
- Example
- A12345678
Things to watch for
- Format-only check — does not confirm the license actually exists, is valid, or is registered to a real driver
- Arizona has issued both letter-prefixed and all-numeric license numbers — this checker accepts either documented form
- Runs entirely in your browser — nothing you type is transmitted or stored
^([A-Z]\d{8}|\d{9})$An Arizona driver’s license number is issued by the Arizona Motor Vehicle Division (MVD), part of the Arizona Department of Transportation (ADOT), in one of two documented shapes: a single letter followed by 8 digits (e.g. A12345678), or a plain 9-digit all-numeric string. Both forms show up on real, currently valid Arizona licenses, which is why a format checker built around only one of them would wrongly reject the other.
What this checker verifies
This tool tests the input against both accepted shapes — letter-plus-8-digits or all-9-digits — and flags anything that matches neither, such as a wrong digit count, a lowercase or misplaced letter, or stray punctuation left in from copy-pasting.
What a pass doesn’t confirm
Neither Arizona format includes a check digit this tool can verify, so matching one of the two documented shapes is as far as a client-side check can go. It doesn’t confirm ADOT actually issued that specific number, that the license is current, or that it’s tied to a real driver — and nothing you type is decoded or stored.
Scope: format-only validation across Arizona’s two documented number styles, running entirely in your browser.

Driver's License FAQ
What does an Arizona driver's license number look like?
Arizona's Motor Vehicle Division (part of ADOT) has issued two documented forms: a single letter followed by 8 digits (e.g. A12345678), and a plain 9-digit all-numeric form. This checker accepts either, since both appear on real, currently valid licenses.
Why does Arizona have two different formats?
ADOT has issued license numbers in both a letter-prefixed and an all-numeric style over time, and older letter-prefixed numbers remain valid on file even as newer numbers may be issued differently — this tool doesn't try to guess which era a number came from.
Does a correctly formatted Arizona number mean it's currently valid?
No. It only confirms the string matches one of the two documented shapes — not that ADOT has that specific number on record or that the license is active.
