- Source: List of Washington (state) area codes
The U.S. state of Washington has six telephone area codes. The state initially used a single area code (206) until it was divided in 1957 with the creation of area code 509 to serve Eastern Washington. In 1995, 206 was split again to serve just the Puget Sound region after area code 360 was created for the remainder of Western Washington. In 1997, area code 425 was assigned to Seattle's Eastside and South Snohomish County suburbs and area code 253 for the Tacoma area, leaving 206 for just the city of Seattle, closely neighboring cities in King and Snohomish counties, and Bainbridge Island in Kitsap County.
