New Brunswick Area Code Information

New Brunswick is currently using two area codes. Area codes 506 and 428 cover all of the province of New Brunswick.

Ten digit dialing (area code + seven digit number) is necessary in the 506/428 overlay because two different homes in the same geographic area can have the same seven digit phone number but each would have a different area code.

From 1947 until 1955 New Brunswick utilized area code 902. When area code 902 was established in 1947 it served the three provinces of New Brunswick, Nova Scotia and Prince Edward Island. Newfoundland and Labrador were added in 1949 when they joined Canada. In 1955 area code 902 was split to form area code 506 which was assigned to New Brunswick, Newfoundland and Labrador. In 1962 area code 506 was split to form area code 709 which was assigned to Newfoundland and Labrador. Area code 506 then served New Brunswick exclusively.
