Saskatchewan Area Code Information
(306 and 474 and 639)
Saskatchewan is currently using three area codes. Saskatchewan utilizes one area code overlay which consists of area code 639 and 474 as an overlay of area code 306. Area codes 306 and 639 and 474 cover all of the province of Saskatchewan.
Changes and History of Saskatchewan Area Codes:
Area code 306 was put into service.
Area code 639 was put into service as an overlay of area code 306.
Area code 474 was put into service as a distributed overlay covering the existing area code overlay (639 and 306) . Area code 474 covers the entire province of Saskatchewan.
Ten digit dialing (area code + seven digit number) is necessary in the 306/639/474 overlay because two different homes in the same geographic area can have the same seven digit phone number but each would have a different area code.
Area codes 306 and 639 and 474 cover the entire province of Saskatchewan including the larger cities and communities of Estevan, Humboldt, Moose Jaw, North Battleford, Prince Albert, Regina, Saskatoon, Swift Current, Weyburn and Yorkton in addition to many smaller communities throughout Saskatchewan.
