Canada currently uses 36 area codes which are assigned to specific geographic areas plus area code 600 which is not assigned to a geographic area. Three provinces which use only one area code are New Brunswick, Newfoundland and Labrador. Several other locations share an area code such as Nova Scotia and Prince Edward Island which use area code 902, as well as, Yukon, Northwest Territories and Nunavut which use area code 867. The province using the most area codes is Ontario which is using thirteen area codes followed by Quebec which is using seven area codes.
In 2012 two new area codes were implement in Canada. Quebec implemented area code 873 as an overlay of area code 819 on September 15, 2012 and Manitoba implemented area code 431 as an overlay of area code 204 on November 3, 2012.
In 2013 four new area codes will be implemented in Canada. Ontario implemented two new area codes 437 and 365 on March 25, 2013. Area code 437 is an overlay of area codes 416 and 647 and area code 365 is an overlay of area codes 905 and 289. Saskatchewan implemented area code 639 as an overlay of area code 306 on May 25, 2013 and British Columbia implemented area code 236 as an overlay of area codes 250, 604 and 778 on June 1, 2013.
Although area codes in Canada are not assigned based upon population, the locations with greater populations have an increased demand for area codes. The non-geographic Canadian area code 600 is reserved for services such as data links, mobile satellite services and ISDN. Three new area codes are assigned but not yet implemented.
Canada participates in the North American Numbering Plan (NANP) which also includes the United States and eighteen countries and island nations in the Caribbean. In Canada the responsibility for area codes is administrated by the Canadian Numbering Administrator which acts as a neutral administrator with decisions about implementation shared by the North American Numbering Plan (NANP) and the ten provinces and three territories. The North American Numbering Plan Administrator (NANP) is responsible for the administration, assignment and management of area codes.
In 1947 when the North American Numbering Plan was established Canada was assigned nine area codes. These included Area Code 204 - Manitoba, Area Code 306 - Saskatchewan, Area Code 403 - Alberta, Area Code 416 - Ontario, Area Code 418 - Quebec, Area Code 514 - Quebec, Area Code 604 - British Columbia, Area Code 613 - Ontario, Area Code 902 - Nova Scotia, Prince Edward Island and New Brunswick.
Within the North American Numbering Plan calls made between participating countries and nations, including Canada, use the country code 1 followed by the area code and local phone number. This results in a consistent dialing pattern of 1 + Area Code + Local Phone Number.
