Who holds these numbers

Iristel Inc. holds the largest share at 5 prefixes, 17.9% of the total, ahead of 11 other carriers. Code by code: in 438, Iristel Inc. leads with 4 of 14 prefixes ahead of 8 others; in 514, Videotron Ltd. leads with 3 of 13 prefixes ahead of 7 others; IXICA Communications Inc. is the only holder in 263. No carrier holds prefixes in every one of Ile-Perrot’s 3 area codes, while 6 appear in just one.

Wireless and wireline

1 of Ile-Perrot’s 28 prefixes (3.6%) are held by carriers whose registered name marks a wireless business: Fido Solutions Inc. Wireline prefixes still outnumber them, carried by Iristel Inc, Videotron Ltd, Fibernetics Corporation and IXICA Communications Inc. 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

Ile-Perrot’s dated assignments run from 2004 to 2024. The busiest period was 2005–2009, when 10 prefixes went to 6 carriers. 2 prefixes (7%) carry no date in the register: these are the historic pre-1999 assignments, the wireline bedrock of the rate centre. Since 2020 another 6 prefixes have been added, so the rate centre is still growing.

Ile-Perrot’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 FGLTEL Inc. (2022), IXICA Communications Inc. (2017) and TekSavvy Solutions Inc (2015), a sign that new carriers are still asking for numbers in Ile-Perrot.

Ile-Perrot has only 28 prefixes, or 280,000 numbers: a small rate centre, where the arrival of a single new carrier visibly changes the landscape.

No single carrier dominates Ile-Perrot: the leader, Iristel Inc., holds only 17.9% of the prefixes against 11 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: 23.1% of the dated prefixes go back to the last ten years, the most active period being 2005–2009. The rate centre is growing at a regular rather than explosive pace.

What a Ile-Perrot number tells you

A number attached to Ile-Perrot 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 12 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 Ile-Perrot: code 438-700 is recorded for Iristel Inc., so every 438-700-XXXX number (10,000 possible) descends from that assignment. “Ile-Perrot, Quebec” there names a rate centre, not a municipality, and several area codes overlay it.
