% of Households with Broadband Internet, by Zip Code (ZCTA5) — Washington

NOTE: Gray indicates insufficient data or a suppressed estimate.

The Seattle-Tacoma-Bellevue metropolitan corridor and surrounding Puget Sound suburbs consistently exhibit the highest broadband adoption rates, with many zip codes reaching 90–100%, while rural eastern Washington and parts of the Olympic Peninsula show notably lower penetration, frequently falling below 70%. A stark urban-rural divide is evident, with isolated pockets of very low connectivity (under 50%) appearing in central Washington's agricultural regions and along the southeastern border near the Blue Mountains. Several small dark-shaded zip codes scattered across the northeast and south-central portions of the state likely correspond to tribal lands or extremely remote communities facing persistent infrastructure gaps.
