Manitoba is as of now utilizing two territory codes. Region code 204 was put into benefit on 01/01/1947 and secured the whole region of Manitoba. Powerful 11/03/12 region code 431 was put into benefit as an overlay of zone code 204. Zone codes 204 and 431 now server the majority of the area of Manitoba. Ten digit dialing ended up required on October 20, 2012.
Ten digit dialing (region code + seven digit number) is vital in the 204/431 overlay since two unique homes in the same geographic territory can have a similar seven digit telephone number however each would have an alternate region code.
