Wireless and wireline

None of Clarenceville’s holders carries a mobility brand in its registered name: all 4 prefixes belong to wireline or wholesale carriers, among them Bell Canada, Fibernetics Corporation, ISP Telecom Inc and IXICA Communications Inc. A call showing a Clarenceville number therefore nominally comes from a landline, cable or VoIP platform rather than a locally assigned cellphone.

How the allocation was built up

Clarenceville’s dated assignments run from 2021 to 2022. The busiest period was 2020–2024, when 3 prefixes went to 3 carriers. 1 prefixes (25%) carry no date in the register: these are the historic pre-1999 assignments, the wireline bedrock of the rate centre. Since 2020 another 3 prefixes have been added, so the rate centre is still growing.

Clarenceville’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 Fibernetics Corporation in 2021. The most recent arrivals are ISP Telecom Inc. (2022), IXICA Communications Inc. (2022) and Fibernetics Corporation (2021), a sign that new carriers are still asking for numbers in Clarenceville.

Clarenceville has just 4 prefixes (40,000 numbers): a very small rate centre, typical of a village or rural area served by a single switching office.

No single carrier dominates Clarenceville: the leader, Bell Canada, holds only 25.0% of the prefixes against 3 competitors, a sign of a highly fragmented market where cable companies, mobility brands and VoIP providers weigh as much as the incumbent.

Growth is recent: 100.0% of the dated prefixes were assigned in the last ten years, peaking in 2020–2024. Clarenceville is among the rate centres where demand for numbers is still rising quickly.

Dialling a Clarenceville number

Clarenceville is served by 3 overlaid area codes (579, 354 and 450). A 450 number is no more “out of town” than a 579 one; from abroad, dial +1 and the full ten digits.

What a Clarenceville number tells you

A number attached to Clarenceville 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 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 Clarenceville: code 450-294 is recorded for Bell Canada, so every 450-294-XXXX number (10,000 possible) descends from that assignment. “Clarenceville, Quebec” there names a rate centre, not a municipality, and several area codes overlay it.

Every Clarenceville prefix

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

Had a call from a Clarenceville 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.

An allocation says who was issued the prefix, not who serves the number today: numbers can be ported between carriers, and caller ID can be spoofed outright.
