Area code 564 is an overlay for western Washington, primarily covering the same region as area code 360, and extending into portions of 206, 253, and 425 as needed. It includes cities such as Bellingham, Olympia, Bremerton, and the San Juan Islands. Introduced in 2017 due to number exhaustion, 564 supports one of the fastest-growing regions in the Pacific Northwest. Olympia serves as the state capital, offering a stable government-driven economy, while Bellingham is home to Western Washington University and a vibrant arts community. Bremerton and other parts of the Kitsap Peninsula are tied closely to the U.S. Navy and shipbuilding. The region features a mix of forested towns, coastal communities, and expanding suburbs with increasing appeal to remote workers and young families. A 564 number offers geographic flexibility and a modern image while tying into the established economic and cultural zones of Puget Sound. It’s ideal for businesses and professionals who want a fresh identity in a scenic, tech-forward, and outdoor-oriented region.
