What is area code 639 – Area code 639 is a telephone area code in the North American Numbering Plan that serves the entire province of Saskatchewan, Canada. It functions as an overlay to area code 306.
Area code 639 covers all of Saskatchewan, including major cities such as Saskatoon, Regina, Moose Jaw, Prince Albert, and Estevan. It was introduced to meet the growing demand for phone numbers in the province.
History and Introduction
Area code 306 had served the entire province since 1947. Due to increasing population and demand for new numbers, area code 639 was activated on November 4, 2012, as an overlay. This means both 306 and 639 serve the same geographic area, and all new numbers can use either code. A third overlay, area code 474, was added later.
