Its numbering plan area (NPA) comprises all of western Washington outside urban King, Pierce, and Snohomish counties and Bainbridge Island, Until January 15, 1995, when the area code commenced service, the numbering plan area (NPA) was served by area code 206, Washington's original area code since 1947.
