A Washington driver’s license number is a 12-character identifier that starts with the letters “WDL” and is followed by nine randomly generated letters and digits. It appears on learner permits, standard licenses, and state ID cards, and the Washington Department of Licensing (DOL) issues and manages it under Title 46 of the Revised Code of Washington.1Washington State Department of Licensing.

What the Number Looks Like
The current format is 12 characters: the “WDL” prefix plus nine characters drawn from A–Z and 0–9.2Washington State Liquor and Cannabis Board. Important Update: RVP Nothing in the sequence is tied to your name, birthday, or any other personal detail. The randomness is deliberate. Someone looking at your card cannot reverse-engineer your identity from the number itself.
Washington used to build the number from a formula. It encoded the first five letters of your last name (padded with asterisks if shorter), your first and middle initials, and a coded version of your birth year, month, and day, plus a checksum. Anyone who understood the pattern could pull personal information straight from the number. Switching to a randomized format closed that gap.2Washington State Liquor and Cannabis Board. Important Update: RVP
If you hold an older card issued before the change, your number will still follow the legacy pattern without the “WDL” prefix.
Where the Number Appears on Your Card
The number is printed near the top of the physical card. On current licenses, the “WDL” prefix and the nine-character string sit above the cardholder’s photo and personal details. Older cards place the legacy number in roughly the same spot.
Washington cards use layered security features to make it hard to alter printed fields without visible damage. Physical card characteristics, encryption, and digital certificates all follow standards published by the American Association of Motor Vehicle Administrators.3American Association of Motor Vehicle Administrators.

How to Look Up Your Number Online
If you don’t have the card in front of you, retrieve the number through the DOL’s License eXpress portal at secure.dol.wa.gov. Create an account or log into an existing one. You’ll need to supply your full legal name, date of birth, and Social Security number so the system can verify your identity against what the DOL has on file.
Once you’re in, the dashboard displays your current license status and your full number. Access is governed by the federal Driver’s Privacy Protection Act, so only you and specifically authorized parties can view the record.4Washington State Department of Licensing. Driver and ID Data Requests Have your identifying details ready before you start. Failed verification attempts can lock you out.
Replacing a Lost or Stolen Card
If the card itself is gone, order a replacement. Washington charges a $20 fee.5Washington State Department of Licensing. Driver Licensing Fees You can request one online through License eXpress, by phone, or in person at a licensing office. Online and phone replacements are capped at three per year.6Washington State Department of Licensing. Replace Your License or Learner Permit
After payment, the system issues a temporary paper permit that authorizes you to drive while the DOL prints and mails the new card. Keep the paper with you until the plastic arrives. It’s your proof of licensing during the gap.
When You’ll Actually Need to Know It
The most common moment people get caught without their number is a move. Washington law requires you to notify the DOL within 10 days of changing your address, and the notification has to include your driver license number.7Justia Law. Washington Code RCW 46.20.205 – Change of Address or Name You can submit the change online through License eXpress or at a DOL office.8Washington State Department of Licensing. Change Your Name or Address on Your Driver License
Missing the 10-day window can cause problems during traffic stops, insurance claims, and anything else that turns on your address of record. The number also comes up when you’re filing insurance paperwork, applying for jobs that check driving records, or verifying identity for financial accounts.
Who Can See the Records Tied to Your Number
The federal Driver’s Privacy Protection Act (DPPA) limits how state motor vehicle agencies share the personal information linked to your license number. The DOL cannot release your records to just anyone who asks.9Office of the Law Revision Counsel. 18 U.S. Code 2721 – Prohibition on Release and Use of Certain Personal Information From State Motor Vehicle Records The statute allows disclosure only in specific situations, including official government functions, motor vehicle safety and recall work, insurance underwriting and claims investigation, civil or criminal legal proceedings, statistical research that doesn’t identify individuals, commercial driver license verification by employers, and any release you specifically authorize.
Washington adds its own restrictions on top of the federal rules. The DOL will only share information when the recipient can legally receive it and has a lawful reason for using it.10Washington State Department of Licensing. How We Use and Protect Your Information Outside those narrow exceptions, your number and the personal data attached to it stay locked down.
