Area code 360 serves western Washington State, excluding the Seattle metro area, and includes cities like Bellingham, Olympia, Vancouver (WA), and Longview. Created in 1995 as a split from area code 206, it was the first area code in the U.S. not to follow the original N0X/N1X format, marking a shift in numbering convention. It has since been overlaid by area codes 564 and 564 expansions. Ten-digit dialing is required. The 360 code covers a diverse landscape of coastlines, forests, and small cities, symbolizing the independent and environmentally conscious culture of the Pacific Northwest.
