The Washington driver’s license format is set by state law and federal card standards: a 12-character number beginning with “WDL,” a horizontal layout for holders 21 and older or a vertical one for anyone younger, and a face marking that tells you at a glance whether the card is a standard license (“federal limits apply”) or an Enhanced Driver License (the words “Enhanced Driver License” with a U.S. flag icon).
The License Number
Every Washington license issued or renewed since September 2018 carries a 12-character identification number. The first three characters are always WDL, identifying the document as a Washington driver’s license. The remaining nine characters are a randomized mix of letters and numbers assigned by the Department of Licensing.
Before 2018, Washington used a Soundex-based encoding system that built your name and date of birth directly into the license number. Anyone who understood Soundex could reverse-engineer personal information from the number itself, and the switch to randomized WDL numbers closed that gap. A pre-2018 license with the older Soundex number remains valid until its next renewal, at which point the holder receives a WDL-prefix number.
Horizontal or Vertical Layout
Washington law requires horizontal cards for people 21 and older and vertical cards for anyone under 21. The layout itself is the age cue for retailers, bartenders, and law enforcement.1Washington State Legislature.

An under-21 card also prints the dates the holder turns 18 and 21, so a clerk can read the threshold without doing math from the birth date. An age indicator sits near the smaller ghost photo, reinforcing whether the holder has reached a legal age.1Washington State Legislature.

Information Printed on the Card
The front of the card carries a primary photo along with your full legal name, date of birth, residential address, and a physical description covering sex, height, weight, and eye color. Endorsements and restrictions tied to your driving privileges also appear on the front. Restriction codes are printed under a “Restrictions” field, with plain-language descriptions on the back. Corrective lenses, for example, print as “Code B.”2Washington State Department of Licensing. Driver License Endorsements and Restrictions
One point of common confusion: Washington does not label its standard license as “Class D.” That designation is used in some other states. Washington reserves the letter classes A, B, and C exclusively for commercial driver’s licenses.3Washington State Department of Licensing. Types of CDLs
Gender Marker
You can select M, F, or X as the gender marker on your license. The Department of Licensing treats this as a standalone choice for the state credential and does not require you to change your birth certificate, Social Security record, or passport first.
Security Features
Washington cards are built with layered anti-counterfeiting measures. A smaller ghost version of the primary photo appears on the card as a secondary check. Fine-line printing and ultraviolet ink are embedded during manufacturing; the UV elements are invisible under normal light and only show up under blacklight, which puts them out of reach of consumer printing equipment.
The back of the card carries a PDF417 two-dimensional barcode following the national AAMVA card design standard. That barcode stores license information in a machine-readable format that law enforcement and point-of-sale systems can scan instantly. The current design also places an image of the state seal on the back and uses a mountain image as the primary background on the front.
Standard License vs. Enhanced Driver License
The most consequential design element on a Washington license is the marking that tells you whether the card is federally accepted.
Standard License
A standard Washington license carries the words federal limits apply on its face, a marking that has appeared on all standard credentials since July 2018. The card is not accepted for boarding domestic flights, entering secure federal facilities, or crossing U.S. land borders. It handles everyday driving and most state-level identification without issue.
Enhanced Driver License
The Enhanced Driver License prints the words Enhanced Driver License across the upper portion of the card, along with a U.S. flag icon near the photo, rather than the star marking used by REAL ID-compliant licenses in many other states.4Transportation Security Administration.

Federal enforcement of the REAL ID Act began on May 7, 2025. Since that date, a standard Washington license alone will not pass TSA airport security; a domestic flyer needs an EDL, a valid U.S. passport, or another federally accepted ID.6Transportation Security Administration.
