How the Driver's License format works
- Format
- 1 letter followed by 8 digits, or 9 digits
- Example
- H12345678
Things to watch for
- Format-only check — does not confirm the license actually exists, is valid, or is registered to a real driver
- Licensing is administered per-county in Hawaii; the leading letter is commonly (but not always) H — this checker accepts any letter
- Runs entirely in your browser — nothing you type is transmitted or stored
^([A-Z]\d{8}|\d{9})$A Hawaii driver’s license number follows one of two documented shapes: a single letter followed by 8 digits (e.g. H12345678), or a plain 9-digit all-numeric form. What makes Hawaii unusual among US states is who issues it — there’s no single statewide DMV; licensing is administered independently by each county’s Division of Motor Vehicles, covering Honolulu, Maui, Hawai’i, and Kaua’i counties, even though the number format itself is consistent across all four.
What this checker verifies
This tool accepts either documented shape and doesn’t require the leading letter to be H specifically — while H is the letter most commonly seen, treating it as mandatory would risk rejecting real numbers that use a different letter or the all-numeric form.
What a pass doesn’t confirm
Neither Hawaii format carries a check digit this tool verifies, so matching one of the two shapes is as far as a client-side check goes. It doesn’t confirm the issuing county actually issued that number, that the license is currently valid, or that it belongs to a real driver.
Scope: format-only validation, entirely client-side.

Driver's License FAQ
Who issues driver's licenses in Hawaii?
Unlike most states, Hawaii has no single centralized DMV — licensing is administered separately by each county's Division of Motor Vehicles (Honolulu, Maui, Hawai'i, and Kaua'i counties). The number format is consistent statewide even though issuance is per-county.
Does a Hawaii license number have to start with the letter H?
Commonly, but not always — this checker accepts any single letter followed by 8 digits, as well as a plain 9-digit numeric form, rather than assuming H specifically.
Does a valid format confirm the license is real?
No. It only confirms the string matches one of the two documented shapes. Confirming the license actually exists requires the issuing county's own DMV records.
