The 403 area code covers southern Alberta, Canada. It serves cities such as Calgary, Lethbridge, Medicine Hat, Brooks, and Red Deer. Originally assigned to all of Alberta when introduced in 1947, its geographic scope was reduced following splits and overlays.

Since overlay area codes like 587 and 825 were introduced, callers within southern Alberta must use 10-digit dialing (area code + phone number) for local calls. This system ensures a steady supply of phone numbers while maintaining connectivity across the region without disrupting existing numbers.

Area code 403 was introduced in 1947 as Alberta’s first area code under the North American Numbering Plan (NANP), covering the entire province. As the population grew and demand for telephone numbers increased, Alberta underwent a significant change in 1999 when the northern region was split off and assigned the new area code 780.

To manage the continued growth in both landline and mobile phone usage, the province shifted to an overlay system. In 2008, area code 587 was introduced as the first overlay, covering all of Alberta and allowing for more efficient number allocation without requiring existing numbers to change.

This was followed by the addition of area code 825 in 2016, further expanding the pool of available numbers. Most recently, in 2022, Alberta saw the introduction of area code 368, the latest overlay added to ensure the province continues to meet growing telecommunications needs. According to the Canadian Numbering Administrator (CNA), these changes were essential to support Alberta’s expanding population and increasing demand for new phone numbers.
