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.
