Area codes 778, 236, and 672

Area codes 778, 236, and 672 are telephone area codes in the North American Numbering Plan (NANP) for the Canadian province of British Columbia. They form an overlay complex with area code 604, which serves only a small southwestern section, the Lower Mainland, of the province (including Vancouver), and area code 250, which serves the rest of the province.

The area codes also serve the small United States community of Hyder, Alaska, which is located along the Canada–United States border near the town of Stewart.

Area code 257 is scheduled for overlay with the existing area codes in the numbering plan area for relief on May 24, 2025.^[1]
