Area code 780
Area code 780 is a telephone area code in the province of Alberta, encompassing the northern two-thirds of the province, including the Edmonton area. 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. Permissive dialing of 403 continued throughout Alberta until May 18, 1999.
Mandatory provincewide 10-digit dialing began on September 12, 2008. This change was done to accommodate area code 587, which had been implemented as a provincewide overlay.
The incumbent local exchange carrier in 780 is Telus. Until its merger with Telus in 1995, over three years prior to the startup of 780, the municipally owned Edmonton Telephones (Ed Tel) served as an ILEC.
The projected exhaust date for area code 780 was October 2009. A new area code, 587, was introduced on September 12, 2008. The 780 area code, simultaneously with area code 403, was overlaid with the new area code, which will cover the entire province. The assignment of 587 numbers in 780 and 403 territory began on September 19, 2008.
