AREA CODE 360

Area code 360 was split from 206 in 1997, and established to serve the western Washington region outside of metropolitan Seattle. The 360 area code was one of the first area codes established to have a middle number other then 0 or 1 (The other was area code 334 in Alabama). Area was originally served by both independent and "Bell" operating companies. Sunset Telephone & Telegraph Co, then Pacific Telephone & Telegraph in 1917, was split to Pacific Northwestern Bell in 1961 and became USWest in 1984 after the divestiture.  USWest became Qwest in 2000 and the current company CenturyLink in 2011. Many of the independents were merged together by Continental Telephone (Contel), which became General Telephone (GTE), than Verizon Northwest and now Frontier Communications. This area uses extensive use of undersea cables connecting the various islands and communities in the Puget Sound to the various Tandem offices.
