Change history

12/21/2022	Zip code boundaries have been edge matched to most recent parcel boundaries, road centerlines and city limits as needed. Nearly all Zip code boundaries in King County were modified in some fashion. Most changes were small, and due to changes in the parcel layer, or new construction on Zip code boundaries where the new address fell within a different Zip code. King County Zip codes that were not altered are 98040, 98047, 98068, 98070, 98154, and 98164. Pierce County Zip code altered: 98422. Snohomish County Zip codes altered are 98012, 98021, 98036, 98072, 98077, 98251, 98272 and 98294. Most of the points that represent Zip codes are generated using the centroid of the Zip code polygon, therefore points generated by this method have changed positions, as the centroid has changed position slightly.
