How to Find the Right Area Code for Montreal and Quebec (2025 Guide)

If you’re calling Montreal or anywhere in Quebec, you’ve probably noticed that the province doesn’t rely on just one area code. With a growing population and millions of mobile numbers, Quebec now uses multiple overlapping codes, each assigned to a specific region.

Whether you’re dialing a business in downtown Montreal or a friend in Quebec City, knowing the correct code can save time — and prevent misdialing.

Why Are There Multiple Area Codes in Quebec?

Canada’s numbering system is part of the North American Numbering Plan (NANP), which standardizes area codes across Canada, the U.S., and parts of the Caribbean.
As populations grow and phone demand increases, overlay area codes are introduced — meaning new codes cover the same region as existing ones.

In Montreal alone, there are three main area codes — and more are being added as the city expands digitally and demographically.
