What Country Is the 639 Area Code For?
Area code 639 is the second area code to cover the province of Saskatchewan, Canada. The other area code that is associated with this area is 306.
Area code 639 is a relatively new area code and was first put into service in May of 2013. Saskatchewan has a number of large cities and communities that are serviced by this area code, including Estavan, Humboldt, Moose Jaw, North Battleford, Prince Albert, Regina, Saskatoon, Swift Current, Weyburn and Yorkton. This new area code for Saskatchewan was implemented as an overlay of the 306 area code, rather than a split, in order to spare rural residents and businesses the need to change their telephone numbers once 10-digit-dialing became mandatory in the province.
