Manitoba will be getting a third area code in October. The new 584 code will complement existing area codes 204 and 431.

A recent estimate suggests that the supply of available Manitoba phone numbers using the 204 or 431 area code will be mostly gone by June 2024. Phone numbers starting with 204 and 431 may still be come available when people discontinue their service, but most of the new numbers that will be issued by providers will start with 584.

Estimates suggest that the 584 area code numbers will run out by 2027 when we will see a fourth area code. The 204 area code was introduced in 1947. The 431 area code was introduced in 2012.
