District of Columbia Driver's License validator
How the Driver's License format works
- Format
- 7 digits, or 9 digits
- Example
- 1234567
Things to watch for
- Format-only check — does not confirm the license actually exists, is valid, or is registered to a real driver
- DC has used both a 7-digit and a 9-digit numeric form — this checker accepts either
- Runs entirely in your browser — nothing you type is transmitted or stored
^(\d{7}|\d{9})$A District of Columbia driver’s license number is issued by DC DMV in one of two documented all-numeric lengths: 7 digits or 9 digits, e.g. 1234567. DC isn’t a US state, but its DMV runs its own independent licensing system with its own number format, distinct from Maryland or Virginia even though both border it — which is why it’s treated as its own entry rather than folded into a neighboring state.
What this checker verifies
This tool confirms the input is purely numeric and matches either the 7-digit or the 9-digit accepted length, catching anything with letters, punctuation, or a digit count that fits neither documented form.
What a pass doesn’t confirm
Neither DC format carries a check digit this tool can verify, so matching one of the two accepted lengths is the strongest confirmation a client-side check can offer. It doesn’t confirm DC DMV 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 accepted lengths, running entirely in your browser.

Driver's License FAQ
What format does a DC driver's license number use?
The District of Columbia DMV has documented two accepted lengths: a 7-digit numeric form and a 9-digit numeric form. This checker accepts either, since both appear on real, currently valid DC licenses.
Why does DC, which isn't a state, have its own driver's license format?
The District of Columbia issues its own driver's licenses through DC DMV, separately from any US state, with its own numbering convention — which is why it gets its own entry here alongside the 50 states.
Does a correctly formatted number confirm the license is valid?
No. It only confirms the digit count matches one of the two documented lengths, not that DC DMV has that number on file or that the license is current.
