Area Code 206 in Washington
Area Code 206 covers the city of Seattle, Shoreline, Lake Forest Park, the islands of Mercer, Bainbridge, and Vashon, and portions of metropolitan Seattle from Des Moines to Woodway. Area Code 206 was one of the area codes that was created when the North American Numbering Plan was introduced in 1947 and originally covered the entire state of Washington. In January 1957, area code 509 was assigned for the eastern two-thirds of Washington. In January 1995, most of the old 206 territory outside of the Seattle/Tacoma area was split off as area code 360, followed by a further split in April 1997 that allocated parts of the area to Area Codes 253 and 425. In January 2017, Area Code 564 was activated as an overlay code for all of the Western Washington State Area Codes (206, 253, 360 and 425) but is currently only being allocated to Area Code 360. Within Area Code 206 there are 7 towns and cities in 2 counties.
Area Code 206 currently has 662 active Exchange Codes, with the last being introduced on 8 November 2017, giving a total number pool of 5,825,000 numbers.
In this Area Code there are 3595 telephone numbers that have been the subject of complaints to the FCC and 24784 telephone numbers that our research shows belong to legitimate businesses.
