Manitoba Area Code Information
(204 and 431 and 584)
Manitoba is currently using three area codes. Area code 204 was put into service on 01/01/1947 and covers the entire province of Manitoba.
In 2012 area code 431 was put into service as an overlay of area code 204. On October 29, 2022 area code 584 was put into service as an overlay of area code 204 and 431. Area codes 204, 431 and 584 now server all of the province of Manitoba.
Ten digit dialing (area code + seven digit number) is necessary in the 204/431/584 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.
