Geographic Coverage & Key Cities
Today, 206 belongs exclusively to Seattle’s urban core and its island neighbors. On the mainland, it covers neighborhoods from Downtown and South Lake Union to Capitol Hill, Ballard, Fremont, the University District, Queen Anne, and Rainier Valley. Across the water, Shoreline continues the 206 lineage to the north, while Burien and SeaTac lie directly south.
Mercer Island keeps the code’s footprint in Eastside luxury, and Bainbridge Island and Vashon Island extend Seattle’s reach into Puget Sound. Cross Lake Washington into Bellevue and Kirkland, and you step into 425 territory; head south to Tacoma, and you switch to 253. Despite the clean boundaries, 206 remains the unmistakable signature of Seattle’s most vibrant communities.
When AT&T first mapped U.S. area codes in 1947, 206 covered the entire state of Washington. By 1957, rising demand led to the creation of 509 for Eastern Washington, and later 360, 425, 253, and 564 would further carve up the region.
Yet for decades, 206 retained its cachet as “Seattle’s number.” Today, 206 remains the fastest way to signal “I’m genuinely Seattle” the moment your number appears on caller ID.

Time Zone & Business Impact
Seattle operates on Pacific Time, shifting between Pacific Standard Time (PST: UTC–8) from November to March and Pacific Daylight Time (PDT: UTC–7) from March to November. Like most states, Washington observes daylight saving time, which helps align with broader national markets.
This Pacific placement gives Seattle-based businesses a strategic advantage when working with both East Coast and international teams. The three-hour difference from Eastern Time allows West Coast professionals to prepare before the rest of the country comes online, while still having meaningful overlap for real-time collaboration. AI-powered answering systems ensure that no matter the time difference, inbound calls are answered with the same professionalism—whether it's morning in Seattle or evening in New York or Tokyo.
