Who holds these numbers

Bell Canada holds the largest share at 7 prefixes, 23.3% of the total, ahead of 10 other carriers. Code by code: in 418, Bell Canada leads with 6 of 15 prefixes ahead of 5 others; in 581, Iristel Inc. leads with 3 of 13 prefixes ahead of 7 others; in 367, Iristel Inc. leads with 1 of 2 prefixes ahead of 1 others.

Wireless and wireline

7 of Riviere-du-Loup’s 30 prefixes (23.3%) are held by carriers whose registered name marks a wireless business: Bell Mobility, TELUS Mobility, Fido Solutions Inc and Rogers Communications Canada Inc. (Wireless). Wireline prefixes still outnumber them, carried by Bell Canada, Videotron Ltd, Iristel Inc and TELUS Quebec. 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

Riviere-du-Loup’s dated assignments run from 2000 to 2025. The busiest period was 2005–2009, when 6 prefixes went to 4 carriers. 5 prefixes (17%) 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.

Riviere-du-Loup’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 Rogers Communications Canada Inc. (Wireless) in 2000. The most recent arrivals are Cogeco Connexion Inc. (2025), Iristel Inc. (2016) and Comwave Networks (2014), a sign that new carriers are still asking for numbers in Riviere-du-Loup.

Riviere-du-Loup’s 30 prefixes provide 300,000 numbers, which corresponds to a mid-sized city or a well-established suburb that every major carrier wants a slice of.

No single carrier dominates Riviere-du-Loup: the leader, Bell Canada, holds only 23.3% 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: 20.0% 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 Riviere-du-Loup number tells you

A number attached to Riviere-du-Loup tells you that its prefix was issued to a carrier for this rate centre in Quebec, most often Bell Canada. 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 Riviere-du-Loup: code 418-860 is recorded for Bell Canada, so every 418-860-XXXX number (10,000 possible) descends from that assignment. “Riviere-du-Loup, Quebec” there names a rate centre, not a municipality, and several area codes overlay it.

   If a caller says they are your bank, the Canada Revenue Agency, a courier or your phone company, hang up and call the organization on the number from its website or your statement, never the number that called you. Caller ID can be faked.

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.

   Forward a scam or spam text to 7726 (SPAM on the keypad). It's free, and your carrier uses it to block the sender. Don't tap links or reply.
