How the Driver's License format works

Format
6 to 10 digits, or 12 digits
Example
12345678

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; current issuance is commonly 8 digits, but the state has documented other lengths too
  • Runs entirely in your browser — nothing you type is transmitted or stored
Regex for Driver's License
^(\d{6,10}|\d{12})$

A South Dakota driver’s license number is a purely numeric string issued by the South Dakota Department of Public Safety (DPS), documented in two separate length clusters: 6 to 10 digits, or exactly 12 digits, with no numbers reported at 11 digits in between. Current issuance is commonly 8 digits, but the state’s documented history includes both the shorter cluster and the standalone 12-digit form.

Reading the format

This tool accepts either the 6-to-10-digit cluster or the exact 12-digit form, rejecting anything in between (11 digits) or outside both ranges entirely — a deliberately precise rule that mirrors the actual gap in South Dakota’s documented issuance history rather than smoothing it into one continuous range.

What a pass doesn’t tell you

South Dakota’s numbers carry no check digit this tool can verify. A pass confirms only that the length fits one of the two documented groups — not that DPS issued that number, that the license is current, or that it belongs to a real driver.

Scope: format-only validation across both documented length groups, entirely client-side.

Driver's License FAQ

How many digits is a South Dakota driver's license number?

Either 6 to 10 digits, or exactly 12 digits — two separate documented clusters rather than one continuous range — issued by the South Dakota Department of Public Safety (DPS). Current issuance is commonly 8 digits.

Why are there two separate length groups instead of one range?

South Dakota's documented lengths cluster around 6-10 digits for most numbers, with a distinct 12-digit form also on record — a gap exists between 10 and 12 digits, so this checker treats them as two separate accepted groups rather than one continuous 6-to-12 range.

Does a valid format confirm the license is currently active?

No. It only confirms the digit count falls in one of the two documented groups, not that DPS has that number on file or that the license is valid.
