Area Code 506 is the original telephone area code for New Brunswick, serving the entire province since 1955. From the Acadian Peninsula to the Saint John River Valley, 506 is woven into the daily rhythm of Maritime life. It connects fishing villages, bilingual cities, and the capital, Fredericton, with a shared sense of pride and tradition. Whether it’s a call from a coastal lobster dock or a provincial agency, 506 is unmistakably New Brunswick. While other regions have expanded their area codes, 506 remains singular, unifying. In the Maritimes, 506 isn’t just practical, it’s iconic.
