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.

Frequently asked questions
What are the area codes for Montreal?
Montreal Island uses 514 and 438 area codes (both overlay the same geographic area). 514 is the original; 438 was added in 2006 to handle number exhaustion. Cell phones, landlines, and VoIP numbers can have either code. All numbers must be dialled with 10 digits — area code + 7-digit local number.
What area codes does Quebec use?
Six area codes: 418/581 (Quebec City, Saguenay, Gaspé), 438/514 (Montreal Island), 450/579 (Laval and surrounding suburbs, off-island), 819/873 (Outaouais and northern Quebec). All Quebec calls require 10-digit dialling since 2006.
Is 438 a Montreal area code?
Yes — 438 is an overlay area code for Montreal Island, added in 2006 to expand available phone numbers. It covers the same geographic area as 514. Most newer cell phones get 438 numbers; many landlines still hold legacy 514 numbers.
What is the Laval area code?
450 and 579 (overlay). Laval, the South Shore (Longueuil, Brossard), and most off-island suburbs use these codes. 579 was added in 2010 to handle number exhaustion. Both codes are dialled the same way: 1+450 or 1+579 followed by the 7-digit number.
Do I need to dial 1 before Montreal phone numbers?
For long-distance calls, yes — dial 1 + area code + 7-digit number. For local Montreal calls, just the 10-digit number (area code + 7-digit) without a 1. Calls within the same area code from a landline may work with 7 digits but cellular networks require 10 digits.
