About area code 204
Area code 204 is a Canadian numbering plan area covering All of Manitoba. It was placed into service in 1947 as one of the original Canadian assignments, and today operates under the Central Time (CST/CDT, UTC-6/-5) time zone.
Numbers in the 204 NPA are issued in central office (CO) blocks of 10,000 to local exchange carriers, who then assign them to subscribers. Because Canada uses a competitive carrier model under CRTC oversight, multiple carriers — both incumbent and competitive — hold blocks within 204. The current carrier of record for any specific number can be looked up via the Canadian Local Number Portability Consortium, but the originally issued carrier is no longer a reliable signal of who actually serves that line.
If you receive a call from a number beginning with 204, the caller is either physically located in or has historically been associated with All of Manitoba. The same applies to overlay codes 431, 584: any of these area codes can correspond to a phone in the same geography, and many households carry numbers from two or three different overlays simultaneously across landlines and mobile devices.
To call a number in 204 from outside Canada and the United States, dial your country's international access prefix, then +1 204 followed by the 7-digit local number. Within the NANP, simply dial 1 followed by all 10 digits — or just the 10 digits if you are also located in an overlay region where 7-digit local dialling is no longer permitted.
