Wireless and wireline

1 of Larder Lake’s 3 prefixes (33.3%) are held by carriers whose registered name marks a wireless business: Bell Mobility. Wireline prefixes still outnumber them, carried by Bell Canada and Northern Telephone Ltd. 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

Larder Lake’s dated assignments run from 2006 to 2025. The busiest period was 2005–2009, when 1 prefixes went to 1 carrier. 1 prefixes (33%) carry no date in the register: these are the historic pre-1999 assignments, the wireline bedrock of the rate centre. Since 2020 another 1 prefixes have been added, so the rate centre is still growing.

Larder Lake’s oldest prefixes, the ones the register leaves undated, belong to Northern Telephone Ltd: this carrier made up the landscape before competition arrived. The first dated assignment went to Bell Mobility in 2006. The most recent arrivals are Bell Canada (2025) and Bell Mobility (2006), a sign that new carriers are still asking for numbers in Larder Lake.

Larder Lake has just 3 prefixes (30,000 numbers): a very small rate centre, typical of a village or rural area served by a single switching office.

No single carrier dominates Larder Lake: the leader, Bell Canada, holds only 33.3% of the prefixes against 2 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: 50.0% of the dated prefixes were assigned in the last ten years, peaking in 2005–2009. Larder Lake is among the rate centres where demand for numbers is still rising quickly.

What a Larder Lake number tells you

A number attached to Larder Lake tells you that its prefix was issued to a carrier for this rate centre in Ontario, 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 3 carriers present here or to a VoIP service usable anywhere. Nor does it tell you who is calling: caller ID can be spoofed, and an Ontario area code is easy to borrow to look local.

Reading a register entry for Larder Lake: code 249-473 is recorded for Bell Canada, so every 249-473-XXXX number (10,000 possible) descends from that assignment. “Larder Lake, Ontario” there names a rate centre, not a municipality, and several area codes overlay it.

Had a call from a Larder Lake 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.

Allocation source: Canadian Numbering Administrator (CNAC), the registry that records which carrier a central-office code was originally issued to. 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.
