About Washington ZIP codes
Washington state is served by 536 ZIP codes spanning 39 counties and 374 cities, ranging from 98001 in the Seattle suburbs to 99403 near the Idaho border. The state's ZIP codes are divided into western and eastern groupings by the Cascade Range, with the 980–986 prefixes concentrated in the rainy, urbanized Puget Sound corridor and the 988–994 prefixes covering the drier, more rural inland regions. King County alone accounts for 91 ZIP codes, reflecting the sheer size and density of the greater Seattle area. Whether you're mailing a package to a Pike Place Market vendor or a wheat farm in the Palouse, Washington's well-organized postal geography makes it easy to navigate one of the most geographically diverse states in the country.
Washington state ZIP codes all begin with 98 or 99, spanning 14 distinct prefixes from 980 through 994. The 980–986 prefixes generally cover the western side of the state, including the Seattle metro area and Puget Sound region, while the 988–994 prefixes serve eastern Washington, including Spokane and the agricultural inland areas. This east-west split in prefixes loosely mirrors the geographic and cultural divide created by the Cascade Mountain Range.
King County has the most ZIP codes in Washington with 91, which reflects its status as the state's most populous county and home to Seattle, Bellevue, and dozens of densely populated suburban communities.
Quick facts
- Seattle's downtown core uses ZIP codes in the 981xx range, with 98101 being one of the most recognized ZIPs in the Pacific Northwest.
- Washington's ZIP codes skip the 987 prefix entirely, jumping from 986 to 988 — a gap that reflects historical postal routing decisions made when the ZIP code system was introduced in 1963.
- The highest ZIP code in Washington, 99403, is assigned to Clarkston, a small city in the far southeastern corner of the state near the Idaho border.
