Canadian telephone numbering

Canadian telephone numbering uses the North American Numbering Plan, incorporating a 10-digit format: a 3-digit area code followed by a 7-digit local number. The area code designates a specific geographic region within Canada. The local number is split into a 3-digit exchange code and a 4-digit subscriber number. While many area codes cover large areas, some regions have multiple codes. These numbers are essential for routing calls accurately and ensure unique identification across the country and the wider North American network. Overall, the system maintains efficient and organized telecommunication connectivity throughout Canada.
