Area Code 306
(306 and 639)
Area Code 306 History:
Area code 306 was officially put into service.
The entire province of Saskatchewan currently uses area code 306.
Area code 639 was officially put into service as an overlay of area code 306 on 05/25/13. Mandatory 10 digit dialing is required.
Area code 474 will be put into service on 10/02/2021 as a distributed overlay covering the existing area code overlay (639 and 306) . Area code 474 will cover the entire province of Saskatchewan.
Ten digit dialing (area code + seven digit number) is necessary in the 306/639 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 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.
