Wireline prefixes still outnumber them, carried by Iristel Inc, TELUS Quebec, Cogeco Connexion Inc and Telecommunications Xittel 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

Sainte-Anne-des-Monts’s dated assignments run from 2001 to 2025. The busiest period was 2020–2024, when 5 prefixes went to 2 carriers. 1 prefixes (8%) 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.

Sainte-Anne-des-Monts’s oldest prefixes, the ones the register leaves undated, belong to TELUS Quebec: this carrier made up the landscape before competition arrived. The first dated assignment went to TELUS Quebec in 2001. The most recent arrivals are Cogeco Connexion Inc. (2025), Iristel Inc. (2018) and Telecommunications Xittel Inc (2013), a sign that new carriers are still asking for numbers in Sainte-Anne-des-Monts.

Sainte-Anne-des-Monts has only 13 prefixes, or 130,000 numbers: a small rate centre, where the arrival of a single new carrier visibly changes the landscape.

Iristel Inc. leads with 46.2% of the prefixes, but 5 competitors have set up in Sainte-Anne-des-Monts: a market where the incumbent keeps the edge without exclusivity.

Growth is recent: 50.0% of the dated prefixes were assigned in the last ten years, peaking in 2020–2024. Sainte-Anne-des-Monts is among the rate centres where demand for numbers is still rising quickly.

What a Sainte-Anne-des-Monts number tells you

A number attached to Sainte-Anne-des-Monts 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 6 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 Sainte-Anne-des-Monts: code 581-439 is recorded for Iristel Inc., so every 581-439-XXXX number (10,000 possible) descends from that assignment. “Sainte-Anne-des-Monts, Quebec” there names a rate centre, not a municipality, and several area codes overlay it.

2. Report the fraud

   Report the call or text to the Canadian Anti-Fraud Centre online or at 1-888-495-8501. If you lost money or gave out personal details, tell your bank first, then your local police.

3. Register on the National Do Not Call List

   Registering a landline or mobile on the National DNCL is free. Registered charities, political parties, newspapers and companies you already do business with may still call.
