206 Area Code – Seattle, Washington: Location, Time Zone & History

Area code 206 was among the original North American Numbering Plan codes assigned in 1947, initially covering the entire state of Washington. As telephone demand grew with regional population increases, the state was progressively divided: 509 split off to serve Eastern Washington, and later 360 was carved out in 1995 to cover areas outside the immediate Seattle metropolitan core. Further splits in 1997 created 253 for the south Puget Sound area, including Tacoma, and 425 for suburbs to the north and east, such as Bellevue and Everett, leaving 206 concentrated on Seattle proper and adjacent communities.

Today, 206 is closely identified with Seattle's urban core and nearby areas including Mercer Island, Vashon Island, Burien, and Tukwila. The region's economy reflects decades of diversification, moving from its early twentieth-century maritime and timber roots toward technology, aerospace, and global trade. Seattle's downtown and surrounding neighborhoods host major corporate headquarters and a dense concentration of software, cloud computing, and e-commerce enterprises, alongside a long-standing aerospace manufacturing presence.
