Where Is Area Code 425?
Area code 425 serves the east and north suburbs of Seattle in western Washington. Bellevue is its primary city, and the code covers portions of King and Snohomish counties in the Puget Sound region.
Major cities include Bellevue, Redmond, Kirkland, Renton, Everett, Lynnwood, Bothell, Issaquah, and Sammamish. The area code crosses city and county boundaries, so it covers parts of both counties rather than one single local government area.
The 425 region includes the eastern shoreline of Lake Washington and Lake Sammamish. It also reaches the Cascade foothills near North Bend and Snoqualmie, along with Puget Sound communities near Edmonds and Mukilteo. Notable sites include Bellevue Downtown Park, Microsoft's headquarters in Redmond, and Boeing's Everett factory.
