Area codes 204, 431, and 584 are telephone area codes in the North American Numbering Plan (NANP) for the Canadian province of Manitoba. Area code 204 is one of the nine original North American area codes assigned to Canada in 1947. Area codes 431 and 584 were assigned to the same numbering plan area (NPA) in 2012 and 2022, respectively, forming an overlay complex.
When the American Telephone and Telegraph Company (AT&T) designed the first comprehensive North American telephone numbering plan in the 1940s, Manitoba was designated as a single numbering plan area (NPA) with area code 204.
In 2009, the Canadian Numbering Administrator forecast that area code 204 would be exhausted within a few years even though there were only 1.2 million people in the entire province. An area code provides about 7.8 million telephone numbers, but Canada uses an allocation scheme that allots all ten thousand numbers of a central office prefix to competitive local exchange carriers even for the smallest hamlets. Canada does not implement number pooling. Therefore, once a number is allocated to a rate centre, it cannot be reassigned elsewhere even if a rate centre has more than enough numbers to service it. The number 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. [1] On July 30, 2012, 10-digit dialing became mandatory throughout the province. [2] Although that had the effect of allocating about 15.6 million numbers to a province of just over 1.2 million people, MTS and other carriers in the province preferred that method to a geographical split, which would have seen one part of the province retain area code 204 and another part receive the new area code 431. The province's telephone companies wanted to spare Manitobans the expense and burden of changing telephone numbers.
Area code 584 was reserved as a third area code for the region in February 2017. [3] It was implemented on October 29, 2022. [4] [5]
The incumbent local exchange carrier for the area codes is Bell MTS.

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.
The North American Numbering Plan (NANP) is a telephone numbering plan for twenty-five regions in twenty countries, primarily in North America and the Caribbean. This group is historically known as World Zone 1 and has the telephone country code 1. Some North American countries, most notably Mexico, do not participate in the NANP.
Area codes 905, 289, 365, and 742 are telephone area codes in the North American Numbering Plan (NANP) for the Golden Horseshoe region that surrounds Lake Ontario in Southern Ontario, Canada. The numbering plan area (NPA) comprises (clockwise) the Niagara Peninsula, the city of Hamilton, the regional municipalities of Halton, Peel, York, Durham, and parts of Northumberland County, but excludes the City of Toronto.
Area codes 519, 226, 548, and 382 are overlay telephone area codes in the North American Numbering Plan (NANP) for most of southwestern Ontario.
Bell MTS Inc. is a subsidiary of BCE Inc. that operates telecommunications services in Manitoba.
In telecommunications, an area code overlay complex is a telephone numbering plan that assigns multiple area codes to a geographic numbering plan area (NPA). Area code overlays are implemented in territories of the North American Numbering Plan (NANP) to mitigate exhaustion of central office codes in growth areas. The method has been in use since 1992, and has been the preferred and exclusive method of relief since 2007.
Ten-digit dialing is a telephone dialing procedure in the countries and territories that are members of the North American Numbering Plan (NANP). It is the practice of including the area code of a telephone number when dialing to initiate a telephone call. When necessary, the ten-digit number may be prefixed with the trunk code 1, which is referred to as 1+10-digit dialing or national format.
Seven-digit dialing is a telephone dialing procedure customary in some territories of the North American Numbering Plan (NANP) for dialing telephone numbers in the same numbering plan area (NPA). NANP telephone numbers consist of ten digits, of which the leading three are the area code. In seven-digit dialing it is not necessary to dial the area code. The procedure is also sometimes known as local format or network format.
Area code 867 is the area code in the North American Numbering Plan (NANP) for the three Canadian territories, all of which are in Northern Canada. The area code was created on October 21, 1997, by combining regions that were previously served with area code 403 and area code 819 in one numbering plan area (NPA). As the least populated NPA in mainland North America, serving about 100,000 people, it is geographically the largest, at 3,921,739 km2 (1,514,192 sq mi), with Alaska (907) a distant second.
Area codes 514, 438, and 263 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 and Île Perrot in the Canadian province of Quebec.
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 telephone area codes in the North American Numbering Plan (NANP) for the 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, 639, and 474 are telephone area codes in the North American Numbering Plan (NANP) for the entire Canadian province of Saskatchewan. Area code 306 is the original area code, and area codes 639 and 474 were 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. This numbering plan area is also served by area codes 587, 825, and 368, which form a complex overlay for all of Alberta.
Area code 780 is a telephone area code in the North American Numbering Plan (NANP) for the Canadian province of Alberta. The numbering plan area comprises the northern two thirds of the province, including the Edmonton area. The area code was established in 1999 in a split of area code 403, which had served the entire province since the establishment of the original North American area codes in 1947. The numbering plan area is also served by area codes 587, 825, and 368, which form a complex overlay for all of Alberta.
Area codes 506 and 428 are the telephone area codes in the North American Numbering Plan (NANP) for the Canadian province of New Brunswick. Area code 506 was created in 1955 in a split of numbering plan area (NPA) 902. Area code 428 was added to the same numbering plan area in 2023 to form an overlay plan of the area.
Area code 604 is a telephone area code in the North American Numbering Plan for southwestern British Columbia, Canada. The numbering plan area comprises the Lower Mainland, Sunshine Coast, Howe Sound / Sea to Sky Corridor, Fraser Valley and the lower Fraser Canyon regions. The major city is Vancouver. The area code is one of the nine original North American area codes assigned to Canada in 1947.
Area code 600 is a telephone area code in the North American Numbering Plan for non-geographic use in Canada of specialized telecommunication services such as telex applications, caller-pays cellular, ISDN, and mobile satellite communication services.
Area codes 587, 825, and 368 are telephone area codes in the North American Numbering Plan (NANP) for the entire Canadian province of Alberta. They form an overlay with both of the previously existing area code 403 of southern Alberta, and northern Alberta's 780. Telephone numbers in area code 587 were allocated starting in late 2008. The complex overlay involving a total of five area codes in Alberta mandated ten-digit dialing throughout Alberta.
