Area Code 204
(204 and 431)
Area Code 204 History:
Area code 204 was put into service and covers the entire province of Manitoba. Effective 11/03/12 area code 431 was placed into service as an overlay of area code 204. Mandatory 10 digit dialing is required.
Ten digit dialing (area code + seven digit number) is necessary in the 204/431 overlay because two different homes in the same geographic area can have the same seven digit phone number but each would have a different area code.
Major cities or places in Manitoba within area code 204 include:
Area codes 204 and 431 serve the larger communities of Brandon, Portage la Prairie, Selkirk, Steinbach, Swan River, Thompson and Winnipeg in addition to the entire province of Manitoba.
