Area codes 306 and 639

Area codes 306 and 639 are telephone area codes in the North American Numbering Plan (NANP) for the entire Canadian province of Saskatchewan. 306 is the original area code, while 639 was added to create an overlay plan for the entire province. The incumbent local exchange carrier is SaskTel.

Area code 306 is one of the original North American area codes that were assigned in 1947 in the contiguous United States and the then-nine-province extent of Canada. Saskatchewan's second area code, 639,[1][2][3] was introduced in 2012.[4]

By the mid-2000s, 306 was on the brink of exhaustion from demand for telecommunication services due to the proliferation of cell phones and other mobile devices requiring unique telephone numbers, particularly in Regina and Saskatoon. All competitive local exchange carriers in Canada are allocated exclusive access to at least one three-digit prefix – comprising 10,000 numbers each – for every rate centre where they plan to offer service, even for the smallest hamlets. While each competing carrier does not necessarily need that many numbers in a particular market, unused numbers are unavailable for use elsewhere once assigned to a particular carrier and rate centre. Since number pooling is not used as a relief measure in Canada, this resulted in thousands of wasted numbers.

In 2011, the Canadian Radio and Television Commission allocated a second area code to Saskatchewan, 639. Unlike what was previously done in jurisdictions such as neighbouring Alberta, it was decided to implement the new area code as an overlay rather than a split. While this had the effect of allocating 15.8 million numbers to a province of just over a million people, SaskTel and other carriers wanted to spare existing subscribers, particularly in rural areas, the burden and expense of changing their numbers. Overlays have become the preferred method of area code relief in Canada; no area codes have been split in the country since 1999. Ten-digit dialing began in 2012, and became mandatory throughout the province in May 2013. Until the implementation of 639, Saskatchewan was the last of Canada's original NPAs where seven-digit dialling had not been broken.

In July 2018, 474 was reserved as a future area code for all of Saskatchewan as 306 and 639 are expected to exhaust as early as June 2022.[5]
