Locations for Area Code - 403

Area Code 403 is the original telephone code for Alberta, covering the entire province from 1947 until it split in the late 1990s. Today, it mainly serves southern Alberta, including Calgary and surrounding communities. As Alberta grew, so did its codes, but 403 remains a coveted number, especially in Calgary, where it signals legacy, leadership, and entrepreneurial spirit. A 403 call might come from an energy exec, a rodeo organizer, or a downtown developer. While newer codes like 587 and 825 serve the same region, 403 holds prestige. In southern Alberta, owning a 403 number is like holding onto part of history.
