Area code 204 covers the entire province of Manitoba, Canada, and has done so since its creation in 1947. It is one of Canada’s original area codes and serves cities such as Winnipeg, Brandon, and Steinbach. In 2012, area code 431 was introduced as an overlay, and 584 followed in 2022, making ten-digit dialing mandatory. The area is known for its vast prairies, multicultural population, and central role in Canadian agriculture and transportation. Despite overlays, 204 remains a highly recognizable and preferred area code in Manitoba, especially for legacy numbers and businesses.
