How the Driver's License format works
- Format
- 1 letter followed by 10 or 12 digits
- Example
- A123456789012
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 is typically the first letter of the holder's last name
- Runs entirely in your browser — nothing you type is transmitted or stored
^[A-Z](\d{10}|\d{12})$A Michigan driver’s license number is one letter followed by either 10 or 12 digits — e.g. A123456789012 — issued by the Michigan Department of State (SOS). Michigan is one of a small group of states, alongside Illinois, where the Secretary of State’s office administers driver licensing rather than a stand-alone DMV, and it shares the name-derived leading-letter convention used by Florida, Illinois, Maryland, and Wisconsin: the letter is typically the first letter of the holder’s last name.
What this checker verifies
This tool accepts a single letter followed by either 10 or 12 digits, catching a digit count that matches neither accepted length, a missing leading letter, or stray characters carried over from a copy-paste.
What a pass doesn’t confirm
Michigan’s number carries no check digit this tool recomputes, so a format match across one of the two accepted lengths is the limit of what a browser-only check confirms. It doesn’t confirm the Department of State actually issued that number, or that the license is currently valid.
Scope: format-only validation, entirely client-side.

Driver's License FAQ
What is the format of a Michigan driver's license number?
One letter followed by either 10 or 12 digits, e.g. A123456789012, issued by the Michigan Department of State (SOS) — Michigan is one of the states where the Secretary of State's office runs driver licensing rather than a separate DMV.
Does the leading letter on a Michigan license mean anything?
It's typically the first letter of the holder's last name under the Department of State's issuance convention, but this checker doesn't verify that encoding — any single letter followed by 10 or 12 digits passes.
Does a valid format confirm the license belongs to a real person?
No. It only confirms the shape is right. Confirming who holds a specific number requires the Department of State's own driver records.
