Area Code 879 To Be Activated in Newfoundland and Labrador

Published: March 23, 2017

The Canadian province of Newfoundland and Labrador, currently using NPA 709 will have a new area code starting in November, 2018. The new area code 879 will overlay the existing NPA 709, covering communities such as Corner Brook, Gander, Grand Falls, Happy Valley - Goose Bay, Labrador City - Wabush, Marystown or St. John's. All local calls originating within the new overlay will eventually be dialed using 10 digits (area code + local number).

Key dates

  • August 17, 2018 - permissive 7/10 digit dialing begins (some local calls within NPA 709 dialed using 7 digits will first be connected to an announcement notifying callers about the new 10 digit dialing requirement)
  • November 10, 2018 - mandatory 10 digit dialing is introduced (again, depending on each carrier's decision whether to play an announcement or not, some local calls within the area will be connected to a network announcement notifying callers that their call can not be completed as dialed and that they must hang up and dial the area code followed by the 7 digit local number
