506 Area Code in New Brunswick, Canada

Area code 506 covers the entire province of New Brunswick, Canada. It was established in 1955, splitting from area code 902, and has since served as the sole area code for the province. Major cities within the 506 region include Fredericton, Moncton, and Saint John. The area is known for its bilingual population, maritime culture, and a mix of urban and rural communities. Due to growing demand, overlay area code 428 was introduced in 2023, making ten-digit dialing mandatory. Despite the overlay, 506 remains a deeply rooted and widely recognized identifier for New Brunswick residents and businesses.
