Who holds these numbers

TELUS Quebec holds the largest share at 4 prefixes, 57.1% of the total, ahead of 3 other carriers. Code by code: in 418, TELUS Quebec leads with 2 of 3 prefixes ahead of 1 others; in 581, TELUS Quebec leads with 2 of 3 prefixes ahead of 1 others; Cogeco Connexion Inc. is the only holder in 367. No carrier holds prefixes in every one of New Carlisle’s 3 area codes, while 3 appear in just one.

Wireless and wireline

2 of New Carlisle’s 7 prefixes (28.6%) are held by carriers whose registered name marks a wireless business: Bell Mobility and TELUS Mobility. Wireline prefixes still outnumber them, carried by TELUS Quebec and Cogeco Connexion 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

New Carlisle’s dated assignments run from 2001 to 2025. The busiest period was 2010–2014, when 2 prefixes went to 2 carriers. 1 prefixes (14%) carry no date in the register: these are the historic pre-1999 assignments, the wireline bedrock of the rate centre. Since 2020 another 2 prefixes have been added, so the rate centre is still growing.

New Carlisle’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), TELUS Mobility (2010) and Bell Mobility (2007), a sign that new carriers are still asking for numbers in New Carlisle.

New Carlisle has just 7 prefixes (70,000 numbers): a very small rate centre, typical of a village or rural area served by a single switching office.

TELUS Quebec leads with 57.1% of the prefixes, but 3 competitors have set up in New Carlisle: a market where the incumbent keeps the edge without exclusivity.

Demand remains steady: 33.3% of the dated prefixes go back to the last ten years, the most active period being 2010–2014. The rate centre is growing at a regular rather than explosive pace.

Dialling a New Carlisle number

New Carlisle is served by 3 overlaid area codes (418, 581 and 367). A 367 number is no more “out of town” than a 418 one; from abroad, dial +1 and the full ten digits.

The numbering neighbourhood

New Carlisle shares area codes 418, 581 and 367 with at least 20 other rate centres, including Quebec, Chicoutimi, Alma, Rimouski, Riviere-du-Loup, Thetford Mines, Sainte-Marie-de-Beauce and Levis. The largest of them, Quebec, holds 282 prefixes in 367, 418 and 581; the smallest on the list, Saint-Henri-de-Levis, has just 16.

What a New Carlisle number tells you

A number attached to New Carlisle tells you that its prefix was issued to a carrier for this rate centre in Quebec, most often TELUS Quebec. It does not tell you where the handset is today: a subscriber may have ported the number to any of the 4 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 New Carlisle: code 418-751 is recorded for TELUS Quebec, so every 418-751-XXXX number (10,000 possible) descends from that assignment. “New Carlisle, Quebec” there names a rate centre, not a municipality, and several area codes overlay it.

Every New Carlisle prefix

Each row is an in-service central-office code recorded for New Carlisle, with its original holder and year of assignment.

Had a call from a New Carlisle number?

No clear pattern in reports on these numbers yet. If a call worried you:

1. Call back on a number you trust

   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.

4. Forward suspicious texts to 7726

   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.
