Who holds these numbers

Code by code: in 819, TELUS Quebec leads with 1 of 2 prefixes ahead of 1 others; in 873, ISP Telecom Inc. leads with 1 of 2 prefixes ahead of 1 others; ISP Telecom Inc. is the only holder in 468. No carrier holds prefixes in every one of St-Adolphe-D'Howard’s 3 area codes, while 1 appears in just one.

Wireless and wireline

None of St-Adolphe-D'Howard’s holders carries a mobility brand in its registered name: all 5 prefixes belong to wireline or wholesale carriers, among them ISP Telecom Inc, TELUS Quebec and Bell Canada. A call showing a St-Adolphe-D'Howard number therefore nominally comes from a landline, cable or VoIP platform rather than a locally assigned cellphone.

How the allocation was built up

St-Adolphe-D'Howard’s dated assignments run from 2008 to 2023. The busiest period was 2005–2009, when 1 prefixes went to 1 carrier. 1 prefixes (20%) 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.

St-Adolphe-D'Howard’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 TELUS Quebec in 2008. The most recent arrivals are ISP Telecom Inc. (2012) and TELUS Quebec (2008), a sign that new carriers are still asking for numbers in St-Adolphe-D'Howard.

St-Adolphe-D'Howard has just 5 prefixes (50,000 numbers): a very small rate centre, typical of a village or rural area served by a single switching office.

ISP Telecom Inc. leads with 40.0% of the prefixes, but 2 competitors have set up in St-Adolphe-D'Howard: a market where the incumbent keeps the edge without exclusivity.

Demand remains steady: 25.0% 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.

Dialling a St-Adolphe-D'Howard number

What a St-Adolphe-D'Howard number tells you

A number attached to St-Adolphe-D'Howard tells you that its prefix was issued to a carrier for this rate centre in Quebec, most often ISP Telecom Inc.. 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 a Quebec area code is easy to borrow to look local.

Reading a register entry for St-Adolphe-D'Howard: code 873-278 is recorded for ISP Telecom Inc., so every 873-278-XXXX number (10,000 possible) descends from that assignment. “St-Adolphe-D'Howard, Quebec” there names a rate centre, not a municipality, and several area codes overlay it.

Had a call from a St-Adolphe-D'Howard 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

   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.
