Information About Postal Codes and Zip Codes
Area code 780 is a telephone area code in the province of Alberta, encompassing the northern two-thirds of the province. The code was established in 1999; prior to this date the entire province was served by the 403 area code. The 780 phone code started use on January 25, 1999; the old 403 code forwarded calls until May 18, 1999.
Mandatory provincewide 10-digit dialing began on September 12, 2008. This change was done to accommodate new area codes that have been assigned to the province for future use.
The incumbent local exchange carrier in 780 is Telus. Until 1995, over three years prior to the startup of 780, the municipally owned Edmonton Telephones existed as an ILEC.
