The proposal to implement 639 as an overlay had the effect of allocating 15.8 million numbers to a province of just over a million people.

By the time the committee's planning document was finalized on July 13, 2011, the recommended new area code had changed to 639, an option that was regarded as equally technically viable. The document did not address this divergence from the CRTC's prior allocation nor give a reason for the change,

In July 2018, area code 474 was reserved as a future area code for all of
Saskatchewan, as area codes 306 and 639 are expected to exhaust their central office prefixes as early as June 2022. The in-service date of area code 474 was October 2, 2021, with no changes in the established dialing
