How Calgary came to have 4 area codes
The original Calgary area code is 403, in service since 1947. As the area ran low on available numbers, overlay codes were added over the same region for new phone lines: 587 (2008), 825 (2016) and 368 (2022). Existing numbers kept their original code — an overlay never forces anyone to change their number — which is why Calgary now uses all 4 codes and every local call is dialed with ten digits.
