Announced earlier this year and scheduled for activation on May 15, 2021, a new area code 368 will be added to an already crowded overlay complex currently serving the province of Alberta, Canada.

Area codes 403 and 780 serve different parts (south/north) of the province’s territory, with Calgary using 403 and Edmonton 780.
The new code is also to cover the entire Albertan territory. No changes will be required in the way calls are made with the introduction of this new area code.

The central Canadian province of Saskatchewan will receive a new area code in 2021. The province currently uses area codes 306 and 639, both covering its entire territory.

There will be no change in how calls are dialed since the province already uses an overlay complex and 10 digit dialing for local calls has been mandatory since 2013.
