Washington Post Offices
Listing data as of July 31, 2026 · Confirm on USPS.com
Washington's 70 post offices serve 63 cities, split by the Cascade Mountains into a wet, densely populated western half around Seattle and Puget Sound and a much drier, more rural eastern half. That divide means weather-related delays are far more common on one side of the state than the other, especially in winter. Find your city in the list below.

File your address change directly with USPS to forward your mail.
Hold Mail Service
