# Area Code 879: Newfoundland and Labrador's Overlay
Area code 879 is an overlay area code that serves Newfoundland and Labrador, a Canadian province located on the eastern edge of North America. Implemented in 2013, the 879 area code was introduced to supplement the existing 709 area code, which had been serving the region since 1947. As the population grew and telecommunications demand increased, a second area code became necessary to provide additional phone numbers while maintaining service continuity. Residents and businesses in Newfoundland and Labrador now use both 709 and 879 area codes, with both codes covering the same geographic territory.
The North American Numbering Plan (NANP) is the standardized system that designates area codes like 879 throughout North America, including the United States, Canada, and several Caribbean nations. Under this system, area codes are assigned by the North American Numbering Plan Administrator based on geographic regions and telecommunications demand. When an area exhausts its available phone numbers, an overlay area codelike 879can be introduced to serve the same region without requiring customers to change their existing phone numbers. This approach allows for efficient number management while minimizing disruption to established telephone subscribers and businesses in the region.
