Nova Scotia is currently using one area code. Nova Scotia is not utilizing any area code overlay plans. Area code 902 covers the entire province of Nova Scotia. Nova Scotia and Prince Edward Island both use 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. Area code 902 then served Nova Scotia and Prince Edward Island exclusively.
