Area codes 204 and 431 are telephone area codes in the North American Numbering Plan (NANP) for the entire Canadian province of Manitoba. 204 is one of the original North American area codes assigned in 1947.
The incumbent local exchange carrier for the area codes is Bell MTS.
In 2009 the Canadian Numbering Administrator forecast that area code 204 would be exhausted within a few years, even though there are only 1.2 million people in the entire province. While an area code provides c. 7.8 million telephone numbers, Canada uses an allocation scheme which allots all 10,000 numbers of a central office prefix to competitive local exchange carriers even for the smallest hamlets, rather than implementing methods of number pooling. Once a number is allocated to a rate centre, it is not possible to reassign it elsewhere, even when a rate centre has more than enough numbers to service it. The exhaustion was caused by the proliferation of cell phones, particularly in and around Winnipeg.
In July 2010, the Canadian Radio-television and Telecommunications Commission approved a province-wide overlay with area code 431, for implementation in November 2012.On July 30, 2012, 10-digit dialing became mandatory throughout the province. Although this had the effect of allocating c. 15.6 million numbers to a province of just over 1.2 million people, MTS and other carriers in the province preferred this method to a geographical split that would have seen one part of the province retain 204 and another part receive 431 as a new area code. The province's telephone companies wanted to spare Manitobans, particularly in rural areas, the expense and burden of changing telephone numbers.
In February 2017, area code 584 was reserved as a third area code for the region.
Calls to the following communities can be direct-dialed from Winnipeg as a local call: Dugald, Lockport, Lorette, Oakbank, St. Adolphe, St. Francois Xavier, Sanford, Starbuck, Stonewall, and Stony Mountain.

Area codes 819 and 873 are area codes for central and western Quebec, Canada, including the Quebec portion of the National Capital Region, and the Hudson Strait and Ungava Bay coastlines of Quebec. Major cities in the 819 territory include Gatineau, Sherbrooke and Trois-Rivières.
Area code 867 is the area code in the North American Numbering Plan (NANP) for the three territories in Northern Canada. It was created on October 21, 1997, from area codes 403 and 819. It is the least populated mainland North American numbering plan area (NPA), serving about one hundred thousand people, but is the geographically largest at 3,921,739 km2 (1,514,192 sq mi), with Alaska a distant second. It is adjacent to Greenland, Russia, and eight provinces or states, more jurisdictions than any other area code in North America. It is also one of four Canadian area codes yet to be overlaid, the others being 506, 709, and 807.
Number pooling is a method of reallocating telephony numbering space in the North American Numbering Plan, primarily in growth areas in the United States.
Area codes 514 and 438 are telephone area codes of the North American Numbering Plan (NANP) for Montreal and most of its on-island suburbs, specifically the Island of Montreal, Île Perrot, and Île Bizard, in the Canadian province of Quebec.
Area code 246 is the telephone area code in the North American Numbering Plan (NANP) for Barbados. Telecommunication services in Barbados are regulated by the Government of Barbados's telecommunications unit. The number 246 spells BIM on an alpha-numeric telephone keypad, a nickname for the island.
Area code 250 is a telephone area code in the North American Numbering Plan (NANP) for the Canadian province of British Columbia outside the Lower Mainland, including Vancouver Island–home to the provincial capital, Victoria–and the province's Interior region. In addition, the numbering plan area extends into the United States community of Hyder, Alaska, located along the Canada–United States border near the town of Stewart. The incumbent local exchange carriers that service the area code are Telus, Northwestel, and CityWest in the city of Prince Rupert.
Area codes 778, 236, and 672 are area codes in the North American Numbering Plan (NANP) for the entire Canadian province of British Columbia. They form an overlay complex with area code 604, which serves only a small southwestern section, the Lower Mainland, of the province, and area code 250, which serves the rest of the province.
Area codes 306 and 639 are telephone area codes in the North American Numbering Plan (NANP) for the entire Canadian province of Saskatchewan. 306 is the original area code, while 639 was added to create an overlay plan for the entire province. The incumbent local exchange carrier is SaskTel.
Area code 403 is a telephone area code in the North American Numbering Plan (NANP) for the Canadian province of Alberta. The numbering plan area encompasses the southern third of the province, which includes the Calgary area.
Area code 807 is a telephone area code in the Canadian province of Ontario, encompassing the Northwestern Ontario region. The 807 Area Code was created in early 1962 when this region of Ontario split from area code 705. The main reason for the split was not the exhaustion of 705, but rather for routing efficiency for calls from Western Canada to northwestern Ontario; such routing efficiency can now be achieved using the highly-computerized digital exchanges that did not exist in the 1960s.
Area code 506 is the telephone area code in the North American Numbering Plan (NANP) for the Canadian province of New Brunswick. The area code was created in 1955 in a split of numbering plan area (NPA) 902.
Area code 604 is a telephone area code that serves southwestern British Columbia, Canada: the Lower Mainland, Sunshine Coast, Howe Sound / Sea to Sky Corridor, Fraser Valley and the lower Fraser Canyon regions. It primarily serves the city of Vancouver and surrounding regions.
020 is the national dialling code for London in the United Kingdom. All subscriber numbers within the area code consist of eight digits and it has capacity for approaching 100 million telephone numbers. The code is used at 170 telephone exchanges in and around Greater London as part of the largest linked numbering scheme in the United Kingdom. In common with all other British area codes the initial '0' is a trunk prefix that is not required when dialling London from abroad.
Telephone numbers in the Philippines follow an open telephone numbering plan and an open dial plan. Both plans are regulated by the National Telecommunications Commission, an attached agency under the Department of Information and Communications Technology (DICT).
In conventional landline telephony, a non-dialable toll point or toll station was a lone station or line serving a rural subscriber many miles from the nearest central office. As it had no home telephone exchange and therefore no local calling area, all connections were obtained manually from the long distance operator.
