Area code 306 covers the entire province of Saskatchewan, Canada, and was one of the original area codes established in 1947. As the population and demand for numbers grew, overlays 639 and 474 were added in 2013 and 2022, respectively, making ten-digit dialing standard across the province. Major cities served include Saskatoon, Regina, and Prince Albert. The region is known for its agriculture, energy production, and strong Indigenous heritage. 306 is a proud symbol of Saskatchewan's identity and continues to be prominently used across government, business, and community sectors.
