California Driver's License validator
How the Driver's License format works
- Format
- 1 letter followed by 7 digits
- Example
- A1234567
Things to watch for
- Format-only check — does not confirm the license actually exists, is valid, or is registered to a real driver
- The number encodes no checksum digit we verify; the leading letter has no fixed meaning
- Runs entirely in your browser — nothing you type is transmitted or stored
^[A-Z]\d{7}$A California driver’s license number follows one of the most consistent formats among US states: a single letter followed by exactly 7 digits, e.g. A1234567, issued by the California Department of Motor Vehicles (DMV). Unlike states such as Florida, Illinois, or Michigan, where the leading letter is typically the first letter of the holder’s last name, California’s leading letter carries no documented rule this checker can verify — it’s simply part of a fixed 8-character shape.
What this checker verifies
This tool confirms the input is exactly one letter followed by 7 digits — no more, no fewer — which is enough to catch a common data-entry slip like a missing digit, an extra character pasted in from a scan, or digits where a letter belongs.
What a pass doesn’t confirm
California’s number encodes no check digit this tool can recompute, so matching the shape is the strongest signal a client-side check can give. A pass doesn’t confirm the DMV actually issued that specific number, that the license is currently valid, or that it belongs to a real driver — and this tool never decodes or stores what you enter.
Scope: format-only validation, running entirely in your browser.

Driver's License FAQ
What is the format of a California driver's license number?
One letter followed by 7 digits, e.g. A1234567, issued by the California Department of Motor Vehicles (DMV). The leading letter has no fixed meaning this tool verifies — it isn't derived from your name or birth date.
Does this checker confirm the license is real or currently valid?
No. It only confirms the string is a letter followed by exactly 7 digits — the same shape a real, expired, or entirely made-up number could share. Confirming validity requires the California DMV's own records.
Is my number stored or sent anywhere when I use this tool?
No. Everything happens locally in your browser; nothing you type is transmitted, logged, or saved.
