Business phone in Laval: 450, not 514
Laval is in the 450 family, not the 514 one. Where that mistake comes from, where it shows up in your own records, and what it costs to leave it.

Laval is not a 514. Île Jésus sits in the 450 family, with 579 and 354 beside it, and it has since June 1998. It is the single most common mistake in a Quebec area-code list, and it is an easy one to make: Laval is an island next to an island, ten minutes from the city.
Where the boundary came from
In June 1998 a new code was split off from 514. The Canadian Numbering Administrator's own description of the event is exact: 514 is retained for the Montreal area, 450 for the area surrounding Montreal. The line followed the island of Montréal, not the metropolitan region, and Laval fell on the outside of it.
Two overlays have landed on 450 since. 579 in August 2010, 354 in October 2022. Both cover the same ground, so a Laval number today is a 450, a 579 or a 354.
The same three codes run right around the ring, which is why a Laval number reads on a call display exactly like one from Longueuil on the south shore, Terrebonne on the north crown or Saint-Jean-sur-Richelieu in the Montérégie.
The June 1998 split kept 514 for the island and gave 450 to the ring around it. Laval landed on the ring.

Where the mistake shows up in your own records
Not in the phone system. It shows up in the paperwork around it, and usually in three places.
A customer list sorted by area code, where every Laval account has been filed under Montréal or under "other" depending on who did the sorting. A line on your site or your van that says you serve the 514, when half your work is north of the river. And a supplier quote that offers you "a 514 for Laval" as though it were the local option.
None of those break a call. They quietly misdescribe your own market to you, which is worse, because you make decisions from that description.
Can a Laval business use a 514 anyway?
You can hold a number from any family, and some providers will offer you one. It is a choice rather than a trick. It is just a weaker choice than it was ten years ago, for two reasons.
The first is supply. A plain 514 is effectively gone, so what is actually on offer is a 438 or a 263. Neither of those reads as more familiar to a Montréal customer than a 450 does, and one of them is newer than the overlay you would be leaving behind. The Montréal codes are worth reading in order.
The second is your own market. To everyone who lives in Laval, 450 is home. You would be trading the code your neighbours recognise for one your Montréal customers may not.
Ten digits means nobody has to guess
Ten-digit local dialling became mandatory in 450, 514 and 438 in 2006, and it is universal across Quebec now. Every caller dials the code and every call display shows it.
That is also why the mistake survives. A code says which numbering territory a number was issued in, and portability means it keeps saying that after the business moves. If you want the full picture of which family covers what, start with Quebec's area codes or the whole of Quebec area codes.
What we are, and what we are not
We supply numbers in 450, 579 and 354 and set them up with you. There is no Ringfully office in Laval, or anywhere else in Quebec. Service is remote, there is no installation visit, and there is nobody local to send.
There is also no self-serve purchase. Numbers are provisioned by hand, one at a time, after a conversation about what the line has to do, and call records are stored in the United States rather than in Canada. If you need an installer who comes to your shop, that is not us, and it is better said now than after the invoice.
If remote works for you, tell us which side of the river your customers are on.
Questions people ask
- Is Laval 514 or 450?
- 450. Île Jésus has been on the 450 side of the boundary since June 1998, when 450 split from 514, and 579 and 354 have since been laid over the same territory. A Laval business line is a 450, a 579 or a 354.
- Why do so many lists put Laval in the 514?
- Because Laval is a large city immediately north of Montréal and people group it with the island out of habit. The 1998 split followed the island, not the metropolitan area, so Laval went with the ring around Montréal rather than with the city on it.
- Can a Laval business get a 514 number anyway?
- Some providers will offer you a number from the Montréal family, and there is nothing improper about holding one. Two things make it a poor trade today: a plain 514 is effectively gone, so what you would get is a 438 or a 263, and a Laval customer already reads 450 as home.
- Which codes cover Laval today?
- 450, 579 and 354. 450 arrived in June 1998, 579 was laid over it in August 2010 and 354 in October 2022. All three serve the same territory, the area surrounding Montréal, and all three dial as ten digits.
- Does Ringfully have an office in Laval?
- No. There is no office in Laval or anywhere else in Quebec, no installation visit and no local staff. Numbers are provisioned by hand rather than bought from a page, so a local number is a local number and never a branch.
