In 1998, a 450 telephone area code was created after being split from area code 514. Due to the high demand for new telephone numbers, 579 was implemented as an overlay for the same geographic regions.

How Does a 579 Phone Number Work for Your Business?
A 579 area code phone number operates under the North American Numbering Plan (NANP) and provides a recognizable local presence across the Montreal suburbs and southern Quebec. This number allows businesses to connect with customers through mobile, landline, and VoIP phone services while reinforcing a regional identity in the Quebec market.
All calls in the 579 region require 10‑digit dialing, meaning callers must dial the area code followed by the seven‑digit number even for local calls. Long‑distance calls within Canada and the U.S. use 1 + 579 + the seven‑digit number, and international callers can reach the number using +1 579 XXXXXXX from mobile phones.
Businesses in this region can get a 579 area code number through virtual or traditional phone providers. This allows them to manage local calls efficiently, respond to customers directly, and maintain a local presence without a physical office in every community.
