I am always on the hunt for license plates and related items to add to my collection – please see my Items wanted page or Contact me directly. Thanks!
Below is an at-a-glance summary of Washington passenger vehicle license plates by year, compiled from plates from my collection. This is meant as a useful tool for dating vintage photos. Please see my Washington State License Plate History page for background.
Many vintage photos show new vehicles with temporary county-issued paper or cardboard licenses. For more information, please see this page.
1905-1915
During this period, registration numbers were assigned by the state, but owners were responsible for providing their own plates (more information here). As a result, there is a wide variety of types and designs, and sometimes the number was simply painted on the vehicle. “WN” and the registration number were the only information displayed.

1916-1962
The state began producing and issuing license plates for the 1916 licensing year. Until 1921, licenses were valid for the state’s fiscal year, not calendar year, with the date on the plate denoting the year of expiration (typically end of February). Thus, a plate dated 1917 was mostly on the road in 1916. From 1922 forward, license years aligned with calendar years.
