902 area code

Area code 902 and overlay area code 782 are the telephone area codes in the Canadian provinces of Nova Scotia and Prince Edward Island. The 902 area code is one of the 86 original area codes established in the North American Numbering Plan in October 1947.

The 902 code originally covered the three Maritime provinces, with Newfoundland added shortly after it joined Canada in 1949. New Brunswick, along with Newfoundland, moved to area code 506 in 1955. Newfoundland (now Newfoundland and Labrador) subsequently received its own area code, 709, in early 1962.

The incumbent local exchange carrier in the 902/782 area is Bell Aliant, which was produced from a merger that included Island Telecom Inc. (formerly Island Telephone, but both were informally shortened to Island Tel), Maritime Telephone and Telegraph (MT&T), New Brunswick Tel (NBTel) and NewTel Communications (NewTel).

902/782 is unusual as it covers two entire provinces, much like area code 867 is shared by the three Canadian territories: Northwest Territories, Nunavut, and Yukon.
