# The 506 Area Code and North American Numbering Plan

The 506 area code serves the entire province of New Brunswick, Canada, making it one of the few area codes in North America that encompasses an entire province. Established in 1947, this area code covers all regions of New Brunswick, from the Bay of Fundy in the southeast to the Acadian Peninsula in the northeast, and includes major cities such as Saint John, Moncton, and Fredericton. As the sole area code for the province, 506 is used by all telephone subscribers in New Brunswick, whether they are residential customers, businesses, or government institutions.

The 506 area code operates within the North American Numbering Plan (NANP), a unified telephone numbering system that coordinates area codes across the United States, Canada, and several Caribbean nations. This system designates three-digit area codes that precede the seven-digit local phone number, creating the standardized format of (XXX) XXX-XXXX. The NANP is administered by the North American Numbering Plan Administration (NANPA) to ensure that area codes are allocated efficiently and that the system remains organized as telecommunications technology evolves. By maintaining a single area code for New Brunswick, the NANP demonstrates how the system accommodates geographic regions while preserving the consistency and reliability of North American telephone communications.
