History of 403 Area Code
The 403 area code is one of the original area codes established in 1947 under the North American Numbering Plan (NANP). It was initially designated to cover all of Alberta, the Yukon, and parts of the Northwest Territories. However, as the years passed by, several changes were made to accommodate the growing need for new phone numbers in Alberta.
The first significant change occurred in 1997 when the area code was split to create area code 780. This new area code took over the northern half of Alberta, including Edmonton, while 403 continued to serve the southern half of the province, including Calgary.
Further changes were made in the coming years as area codes 587 and 825 were added in 2008 and 2016 as overlays. Most recently, in 2022, area code 368 was also introduced as an overlay to serve the growing demand for phone services in Alberta.
