Area code 450 at a glance
Where area code 450 comes from
The 450 was born in 1998 from the 514 split: the island kept its code, the whole ring took the new one. As in Toronto five years earlier, the division ended up naming an entire region in everyday speech.
What 450 covers
A belt around Montreal, minus the island. Laval to the north, the South Shore with Longueuil and Brossard, the lower Laurentians up to Saint-Jérôme, Lanaudière toward Repentigny and Terrebonne, and the Montérégie out to Granby, Saint-Hyacinthe and Valleyfield.

Who answers the phone in 450
The ring concentrates manufacturing, food processing, distribution and residential construction. Many service businesses here cover both their own suburb and the island, which makes the choice of area code a strategic one.
The phone day to day in 450
The ring runs on Eastern time but over distances that change everything: Valleyfield to Sorel-Tracy is two hours of driving. Service businesses plan by sector and by half-day. Building trades start early, often before seven, and the noon window disappears into travel. Winter adds its share: appointments move, and the phone becomes the only reliable way to reschedule them.
450 and its neighbours
The 450 encircles the island without ever touching it, and shares its territory with 579. Toward Montreal you shift to 514 or 438; eastward to 819 for the Estrie and Mauricie; northeast to 418. Many ring businesses add a 514 to sell on the island, where the prefix weighs on the decision to call back.
What a 450 number changes for a business
In the suburbs a local number proves you are from nearby. A Saint-Hyacinthe customer wants to know the supplier is not driving down from Montreal for every visit. Because the ring is so wide, many businesses open a number per sub-region so each listing shows the expected code.
How to dial a 450 number
Ten-digit dialing is mandatory in the 450 area (overlaid with 579, 354).
Why a 450 number for your business?
A 450 number gives you a local presence in Greater Montreal suburbs. Calls with a local caller ID get picked up more often than an unknown or toll-free number, and your clients recognize a neighbour rather than an out-of-province cold call.
- Picked up more often than a toll-free or out-of-province number.
- Local trust: clients prefer a vendor from their region.
- Remote team: everyone calls from anywhere under the same local number.
- Easy to recall for cards, vehicles and word of mouth.
Who uses a 450 number?
Practices and professional services
Accountants, notaries, consultants: the client calls back a number they recognise, and every exchange stays attached to their file. Missed calls go back out as an automatic text instead of sitting in a mailbox nobody checks.
Shops and workshops
The phone question is short: do you have it, when do you close, what does it cost. The number rings wherever someone can answer, and texting handles the rest without tying up the counter.
Home services
Plumbers, electricians, HVAC: the whole team shares one local number, calls ring whoever's free, nothing slips.
Real estate
A local number doesn't get screened like an out-of-province one. Every call and text stays on the contact record.
Health & clinics
A voice menu routes to scheduling or billing; after hours, urgent calls go through, the rest to voicemail.
Professional services
Accountants, lawyers, advisors: every call is logged, and an AI summary lists action items after the conversation.
Sales
Reps prospect with a local caller ID — picked up more often than an unknown or toll-free number.
Retail & delivery
Order confirmations and delivery windows by SMS from the same local number customers already know.

Porting an existing 450 number
If you already have a 450 number, you do not have to change it. Number portability is a regulated right in Canada: your current provider cannot hold on to a number that belongs to you. The transfer goes to your own telecom account, not ours, which means the number stays in your name once it lands.
In practice you need a recent bill from the current provider and a signed authorisation. Timing depends on the line type, typically a few business days. The line keeps working during the transfer: the switch happens on an agreed date, not into a void.
What a 450 number really costs
There are two bills, and that is deliberate. Relay software comes from us, in Canadian dollars, billed per team with seats included. Telecom comes from your provider, at their published rate, on an account in your name. We do not resell the minute and we take no margin on it.
The consequence is easy to verify: you can open your provider's dashboard and see the real price of every call and every text. That is what changes as volume grows, because a hidden margin on the minute costs more and more the more you call.
Texting from a Canadian number: what to know
Since March 2025, a Canadian number used for business texting requires A2P 10DLC registration or identity verification with the carrier. Many sites still present this as an American matter: it is not, the rule also applies to texting a Canadian customer from a 450 number. The process happens on your own telecom account, with your business details, and like the number it stays yours.
450 or 579, 354: which one?
These codes cover the same territory, down to the street. Technically they are equivalent: same local zone, same rates, same ten-digit dialling. The only real difference is age. Since 450 has been in service since 1998, it reads as the most established, and it is also the hardest to get. The newer overlays offer identical reach with far better availability.
The more useful question is how many numbers you need. A business serving several cities often does better opening one per market than forcing a single number on everyone: the local listing shows the expected code, and the calls still land in the same shared inbox. Because the numbers live on your own telecom account, adding one does not mean renegotiating anything.
One last point, often forgotten: the number you display has to be the one that rings when somebody calls back. A local code on a listing followed by a callback from a placeless number cancels the whole benefit. That is why the outbound call goes out from the same 450 number as the inbound one.
