Information About Postal Codes and Zip Codes
Area code 506 is the telephone area code in the Canadian province of New Brunswick, encompassing the entire province. The code was created in 1955, when New Brunswick and Newfoundland (including Labrador) split from the 902 area code; Newfoundland and Labrador split to its own 709 area code in early 1962.
The incumbent local exchange carrier in 506 is Aliant (part of the Bell Aliant income trust), which was produced from a merger that included NBTel. Since 2005, local telephone service through Eastlink Communications has also been available in the town of Sackville. It is not expected to exhaust for at least another 15 to 25 years.
