368 Area Code – Calgary, Alberta: Location, Time Zone & History

Oil and gas remain central to the economy served by area code 368, alongside agriculture, technology, tourism, and construction — a mix that spans Alberta's largest cities and its resource-driven communities alike. Calgary and Edmonton anchor the numbering territory, with Red Deer, Fort McMurray, Grande Prairie, and Lethbridge rounding out the areas it covers.

What sets 368 apart from most area codes is its scope: rather than covering a single city or metropolitan region, it is a province-wide overlay, sharing the same geographic territory as three existing codes — 403, 780, and 587 — plus the more recent 825. The CRTC approved this overlay plan in 2019 specifically to relieve exhaustion of the 825 numbering pool, and 368 went into service on April 23, 2022. Because it overlays the entire province rather than a single region, its introduction made ten-digit dialing mandatory throughout Alberta.

As of the 2021 Census, the province's population stood at roughly 4.26 million, underscoring the scale of the numbering plan area that 368, 403, 780, 587, and 825 now share between them.
