Area Code 639

Area Code 639 History:

Area code 639 was officially put into service on 05/25/13. Area code 639 is an overlay of area code 306. Mandatory 10 digit dialing is required.

Area code 474 was put into service on 10/02/2021 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.
