Geographic Regions and Area Codes

Area code 506 serves the entire province of New Brunswick, Canada. This includes major cities such as Fredericton, Moncton, Saint John, Dieppe, Bathurst, Miramichi, Campbellton, and Edmundston, as well as other smaller communities throughout the province. In 2023, area code 428 was added to the same numbering plan area to form an overlay plan. This means that both area codes now serve the same geographic region, providing additional numbering options for businesses and residents. The introduction of the new area code ensures that the growing demand for phone numbers in New Brunswick can be met without changing existing numbers.
