About 450 Area Code
Area code 450 covers the off-island suburbs of Montreal and much of southern Quebec, including major cities like Longueuil, Laval, Terrebonne, Saint-Jean-sur-Richelieu, Brossard, Repentigny, Saint-Jerome, and Granby. It entered service on June 13, 1998, split from the original 514 area code to handle rapid suburban growth around Montreal Island. The 450 territory spans the administrative regions of Monteregie, Laurentides, Lanaudiere, and the City of Laval. Two overlay codes, 579 (added in 2010) and 354 (added in 2022), now share the same geographic footprint.
The 450 region is one of Canada's most economically active suburban corridors. Laval anchors a significant biotechnology and life sciences cluster, while Longueuil hosts aerospace manufacturing operations tied into Montreal's broader aerospace ecosystem. Monteregie contributes substantially to Quebec's provincial GDP through manufacturing, agri-food production, and commercial development. Businesses here use 450 numbers for appointment scheduling, customer support, logistics coordination, and field service dispatch, all workflows that benefit from a familiar local prefix rather than a generic national line.
FoneSwift shows live 450 number inventory directly on this page. You can filter by Voice, SMS, and MMS capabilities before purchasing. Because 450 is one of the most in-demand area codes in Quebec, availability fluctuates. If a 450 number is not available when you search, the overlay codes 579 and 354 cover the exact same geographic area and carry the same local recognition with Montreal-area audiences.
If your business serves the Greater Montreal suburbs, display your number in both local and international formats, for example (450) 555-1234 and +1 450 555 1234, to match how Quebec customers expect to see contact details. For outbound SMS campaigns, Canadian carriers require A2P registration, and CASL mandates prior consent, sender identification, and a working opt-out in every commercial message. If you're porting an existing 450 number, check our porting guide; most geographic ports complete within 5 to 10 business days.
10-digit dialing (area code + 7-digit number) is required within the 450 region. For business SMS, comply with CASL by obtaining prior consent, including sender identification, and providing an opt-out mechanism. Register new Canadian long-code numbers for A2P use with your messaging provider before launching campaigns.
Area code 450 uses Eastern Standard Time (EST, UTC-5) and observes Daylight Saving Time, shifting to Eastern Daylight Time (EDT, UTC-4) from mid-March through early November. Standard business hours in the region align with the Eastern Time Zone shared by Toronto, Ottawa, and New York City.
Local 450 numbers deliver strong recognition with Montreal-area audiences and typically outperform toll-free or out-of-province numbers for answer rates. If 450 inventory is limited, overlay codes 579 and 354 cover the identical geographic area and carry equal local credibility. Bell Canada is the incumbent carrier; Videotron and Telus are the primary competitive carriers in the region.
Quick Facts about 450 Area Code
Interesting tidbits about this area code 450
The "Doughnut" Code
Area code 450 completely encircles 514, the code for Montreal Island, making it one of only six "doughnut area codes" in the North American Numbering Plan and the only such pairing in Canada.
Known as "Le 450"
Montrealers informally call the off-island suburbs "le 450," much like Toronto-area residents refer to their suburbs as "the 905." The nickname has become a genuine cultural shorthand for suburban Quebec life.
Aerospace Hub in Longueuil
Longueuil is home to a major aerospace manufacturing hub integrated into the broader Montreal aerospace corridor, one of the largest concentrations of aerospace activity anywhere in the world.
Biotech Powerhouse in Laval
Laval, Quebec's third-largest city, hosts a prominent biotechnology and life sciences cluster, making 450 a key area code for research organizations, pharma companies, and medical service providers.
Borders New York State
The 450 territory extends southward all the way to the New York State border. Communities in southern Monteregie sit right on the Canada-US boundary, giving the area code an international edge.
Three Codes, One Region
Number exhaustion kept pace with suburban growth, so two overlays were needed: 579 in 2010 and 354 in 2022. Callers in this zone may have any of three area codes but are all neighbours.

How Does Local 450 Phone Numbers Work?
A local business number is a structured telephone identifier that tells networks where to route calls and messages.

- Subscriber number (eg. 1234): the unique line assigned to a person, extension, or device.
