About 579 Area Code
Area code 579 is a Canadian overlay code serving the off-island suburbs of Montreal and the broader southern Quebec region. It went into service on August 21, 2010 as the 351st area code in North America and Quebec's 7th, created to relieve number exhaustion in the 450 area code. Today, 579 shares the same geographic footprint as both 450 and the more recent 354 overlay (added in October 2022), covering major cities like Laval, Longueuil, Terrebonne, Saint-Jérôme, Saint-Jean-sur-Richelieu, Granby, and Saint-Hyacinthe across Montérégie, Laval, Laurentides, and Lanaudière. The incumbent local exchange carrier (ILEC) for the region is Bell Canada, with Vidéotron and Telus operating as the major competitive carriers.
The 579 region is one of the most economically dynamic corridors in Canada. Longueuil hosts global aerospace leaders like Pratt & Whitney Canada, while Mirabel is home to Bell Textron Canada's helicopter manufacturing operations. Montérégie's agri-food sector earns it the title of "Garden of Quebec," with producers such as Lassonde Industries and Agropur anchoring regional supply chains. The North and South Shore retail corridors, logistics hubs along Autoroutes 15 and 20, and a rapidly growing tech cluster in Laval make 579 numbers highly relevant for manufacturing, healthcare, distribution, and professional services firms that need to communicate with a predominantly francophone customer base.
FoneSwift lists live 579 number inventory with per-number capability flags for Voice, SMS, and MMS. Because 579 is an overlay, callers within the region are already comfortable seeing 450, 579, and 354 numbers side by side; any of these codes signals a genuine local presence. If a specific 579 number is not available immediately, nearby codes like 450 or 354 cover the same geographic territory and deliver an equally strong local signal to Quebec subscribers.
If your business targets French-speaking customers in the Montreal suburbs, publish numbers in both local and E.164 formats, for example (579) 555-1234 and +1 579 555-1234, and make sure any A2P SMS campaigns are registered with Canadian carriers per CRTC guidelines. Porting an existing 450 or 354 number into FoneSwift is supported where carriers allow geographic port-in; see our porting guide for timelines. Keeping the same number avoids disrupting customer familiarity in a market where trust is built slowly.
10-digit dialing is required throughout the 579/450/354 overlay region. Businesses running A2P SMS campaigns in Canada must comply with CRTC guidelines and carrier registration requirements for commercial messaging.
Area code 579 operates in the Eastern Time Zone (EST, UTC-5 in winter; EDT, UTC-4 in summer). Quebec observes Daylight Saving Time, so standard business hours shift between EST and EDT seasonally. Plan outbound campaigns and call scheduling accordingly.
As an overlay code, 579 carries the same local weight as 450 and 354 in the eyes of Quebec subscribers. If 579 inventory is limited, nearby codes 450 and 354 cover the exact same territory. For audiences on the Island of Montreal, consider 514 or 438 numbers instead.
Quick Facts about 579 Area Code
Interesting tidbits about this area code 579
Born from number exhaustion
The 579 code was introduced in 2010 specifically because the 450 area code was running out of assignable numbers due to rapid suburban population growth and the explosion of mobile devices across the Montreal region.
A three-code overlay stack
The 450 territory now carries three simultaneous area codes: 450, 579, and 354. That makes southern Quebec one of the few regions in Canada where a single city can display three different local area codes.
Aerospace capital of Canada
Longueuil, right in the heart of 579 territory, is home to Pratt & Whitney Canada and is part of what the industry calls the "Montreal Aerospace Cluster," one of the world's top three aerospace manufacturing hubs.
The Garden of Quebec
Montérégie, the agricultural heartland within the 579 footprint, is nicknamed the Garden of Quebec. It produces a significant share of the province's fruits, vegetables, and dairy, with agri-food giants like Lassonde Industries calling it home.
Predominantly francophone
The 579 region is deeply rooted in French-Canadian culture, with French as the everyday language of commerce and daily life. Businesses that localize their messaging in French alongside a 579 number build credibility much faster in this market.
Doughnut code neighbor
450/579/354 completely encircles area code 514 (the Island of Montreal), making it one of only six "doughnut area code" pairs in the entire North American Numbering Plan, and the only one in Canada.

How Does Local 579 Phone Numbers Work?
A local business number is a structured telephone identifier that tells networks where to route calls and messages. When you use a 579 number in Laval and Quebec, the digits signal the international gateway, the geographic region, the local exchange and the specific subscriber, so calls reach the right destination quickly and reliably.
The typical parts of a Canada local number are:
- Country code (+1): identifies Canada for international routing.
- Area code (579): directs the call to the Laval / Quebec region.
- Central office / exchange (eg. 555): narrows the call to a local switching area or rate center.
- Subscriber number (eg. 1234): the unique line assigned to a person, extension, or device.
Example formats:
| International Format (E.164) | +1 579 555 1234 |
| Local Format (National) | (579) 555-1234 |
