Where is Calgary?

Calgary is a popular city located in the province of Alberta, Canada. Edmonton, Airdrie, Cochrane, Okotoks, and Black Diamond are the nearest cities. The population rate in this city is around 1.68 million, according to the latest update. Given this large population, it is crucial to have a system that can effectively manage telecommunication services. To organize and manage the distribution of phone numbers among residents and businesses, the 403 area code was introduced in 1947. Later, the 583 and 825 area codes were added to meet the growing demand for phone numbers in the region.

With a favorable business environment and smooth connectivity, Calgary has experienced significant development in finance, IT, health, education, construction, tourism, and hospitality. These sectors contribute to its strong economic growth, with over $18.35 billion in foreign direct investment (FDI) since 2015.

Understanding Area Codes in Calgary, Canada

Calgary uses three area codes to meet the demand for phone numbers. 403, 587, and 825 are area codes in Calgary.

  • 403 area code: 403 is one of the original North American Numbering Plan (NANP) area codes established in 1947. Though it initially covered the entire province of Alberta, in 1999, its coverage was reduced. Today, it serves southern Alberta, including Calgary.
  • 587 area code: 587 is an overlay area code introduced in 2008 to meet the growing demand for phone numbers for the entire Alberta province. It was the first time the province utilized an overlay code to address number exhaustion. Today, it co-exists with both the 403 and 780 phone codes.
  • 825 area code: 825 was introduced in 2016 as an overlay for the region to ensure an adequate supply of phone numbers. Like 587, 825 serves the entire province of Alberta. It provided additional phone numbers while allowing the existing customer to retain their current numbers. The business chooses 825 area codes to provide service across Alberta.
