Laval-Est’s share of its area codes

Within area code 579, Laval-Est accounts for only 11 of 644 prefixes (1.7%): the code is dominated by Granby and spread over 126 rate centres. Within area code 450, Laval-Est accounts for only 9 of 775 prefixes (1.2%): the code is dominated by Granby and spread over 129 rate centres.

Who holds these numbers

Iristel Inc. holds the largest share at 7 prefixes, 35.0% of the total, ahead of 10 other carriers. Code by code: in 579, Iristel Inc. leads with 4 of 11 prefixes ahead of 6 others; in 450, Iristel Inc. leads with 3 of 9 prefixes ahead of 5 others. 2 carriers hold prefixes in every one of Laval-Est’s 2 area codes, while 9 appear in just one.

Wireless and wireline

1 of Laval-Est’s 20 prefixes (5.0%) are held by carriers whose registered name marks a wireless business: Fido Solutions Inc. Wireline prefixes still outnumber them, carried by Iristel Inc, Fibernetics Corporation, IXICA Communications Inc and Videotron Ltd. This is a sort by name, not a licence lookup, and a mobile prefix may have been ported to another network since.

How the allocation was built up

Laval-Est’s dated assignments run from 2004 to 2024. The busiest period was 2015–2019, when 5 prefixes went to 3 carriers. 1 prefixes (5%) carry no date in the register: these are the historic pre-1999 assignments, the wireline bedrock of the rate centre. Since 2020 another 5 prefixes have been added, so the rate centre is still growing.

Laval-Est’s oldest prefixes, the ones the register leaves undated, belong to Bell Canada: this carrier made up the landscape before competition arrived. The first dated assignment went to Videotron Ltd. in 2004. The most recent arrivals are IXICA Communications Inc. (2021), Distributel (2018) and InnSysVoice Corp (2015), a sign that new carriers are still asking for numbers in Laval-Est.

Laval-Est has only 20 prefixes, or 200,000 numbers: a small rate centre, where the arrival of a single new carrier visibly changes the landscape.

No single carrier dominates Laval-Est: the leader, Iristel Inc., holds only 35.0% of the prefixes against 10 competitors, a sign of a highly fragmented market where cable companies, mobility brands and VoIP providers weigh as much as the incumbent.

Demand remains steady: 26.3% of the dated prefixes go back to the last ten years, the most active period being 2015–2019. The rate centre is growing at a regular rather than explosive pace.

Dialling a Laval-Est number

Laval-Est is served by 2 overlaid area codes (579 and 450). A 450 number is no more “out of town” than a 579 one; from abroad, dial +1 and the full ten digits.

The numbering neighbourhood

Laval-Est shares area codes 579 and 450 with at least 20 other rate centres, including Granby, Joliette, St-Jerome, St-Hyacinthe, Longueuil, Ste-Therese, Pont-Viau and Sorel. The largest of them, Granby, holds 51 prefixes in 450 and 579; the smallest on the list, Terrebonne, has just 17.

What a Laval-Est number tells you

A number attached to Laval-Est tells you that its prefix was issued to a carrier for this rate centre in Quebec, most often Iristel Inc.. It does not tell you where the handset is today: a subscriber may have ported the number to any of the 11 carriers present here or to a VoIP service usable anywhere. Nor does it tell you who is calling: caller ID can be spoofed, and a Quebec area code is easy to borrow to look local.

Reading a register entry for Laval-Est: code 579-568 is recorded for Iristel Inc., so every 579-568-XXXX number (10,000 possible) descends from that assignment. “Laval-Est, Quebec” there names a rate centre, not a municipality, and several area codes overlay it.
