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
- UNCERTAIN: some references describe an older alternating letter-digit-letter-digit-letter legacy format not covered here — flag for review if a real KS number fails
- Runs entirely in your browser — nothing you type is transmitted or stored
^([A-Z]\d{8}|\d{9})$A Kansas driver’s license number follows one of two documented shapes issued by the Kansas Division of Vehicles: a single letter followed by 8 digits (e.g. A12345678), or a plain 9-digit all-numeric string. Some references also describe an older, alternating letter-digit-letter-digit-letter legacy format from further back in Kansas’s issuance history; because that pattern isn’t consistently corroborated, this checker focuses on the two well-documented current shapes rather than guessing at the older one.
What this checker verifies
This tool accepts either the letter-plus-8-digits form or the 9-digit numeric form, catching anything that fits neither — a missing digit, a misplaced letter, or an unexpected length.
What a pass doesn’t confirm
Neither accepted Kansas shape carries a check digit this tool verifies, so a format match is the strongest confirmation a client-side check gives. It doesn’t confirm the Division of Vehicles actually issued that number, that the license is currently valid, or that it belongs to a real driver — and nothing you type is decoded or stored.
Scope: format-only validation across both documented forms, entirely client-side.

Driver's License FAQ
What is the format of a Kansas driver's license number?
One letter followed by 8 digits (e.g. A12345678), or a plain 9-digit all-numeric form, issued by the Kansas Division of Vehicles. Both shapes are accepted since both appear on real, currently valid Kansas licenses.
Are there older Kansas formats this checker doesn't cover?
Some references describe an older alternating letter-digit-letter-digit-letter legacy format that isn't covered here. If a genuine older Kansas number fails this check, that undocumented legacy format is the likely reason.
Does a valid format mean the license is currently active?
No. It only confirms the string matches one of the two documented shapes, not that the Division of Vehicles has that number on file or that the license is valid.
