Area codes 204 and 431 are the North American telephone area codes for the Canadian province of Manitoba, encompassing the province. 204 is one of the original 86 area codes assigned in 1947 in the contiguous United States and the then-nine-province extent of Canada.

The incumbent local exchange carrier for the 204 and 431 area codes is MTS.

In 2009 the Canadian Numbering Administrator forecast that the numbers for area code 204 in Manitoba would be exhausted within a few years, despite there only being 1.2 million people in the entire province. (An area code typically holds 7.8 million possible numbers, but Canada uses an inefficient allocation scheme with no number pooling and separate rate centres for every tiny village.) 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 came into effect in the area code.[2] This decision, rather than a geographical split of the area code, was made to spare mobile telephone companies in rural Manitoba the expense and burden of having to change existing subscribers' numbers.

Communities included[edit]

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.
