Ste-Anne-des-Plaines’s share of its area codes

Within area code 450, Ste-Anne-des-Plaines accounts for only 6 of 775 prefixes (0.8%): the code is dominated by Granby and spread over 129 rate centres. Within area code 579, Ste-Anne-des-Plaines accounts for only 3 of 644 prefixes (0.5%): the code is dominated by Granby and spread over 126 rate centres.

Who holds these numbers

Videotron Ltd. holds the largest share at 4 prefixes, 44.4% of the total, ahead of 4 other carriers. Code by code: in 450, Videotron Ltd. leads with 4 of 6 prefixes ahead of 1 others; in 579, Distributel leads with 1 of 3 prefixes ahead of 2 others. No carrier holds prefixes in every one of Ste-Anne-des-Plaines’s 2 area codes, while 5 appear in just one.

Wireless and wireline

None of Ste-Anne-des-Plaines’s holders carries a mobility brand in its registered name: all 9 prefixes belong to wireline or wholesale carriers, among them Videotron Ltd, Bell Canada, Distributel and Fibernetics Corporation. A call showing a Ste-Anne-des-Plaines number therefore nominally comes from a landline, cable or VoIP platform rather than a locally assigned cellphone.

How the allocation was built up

Ste-Anne-des-Plaines’s dated assignments run from 2004 to 2022. The busiest period was 2005–2009, when 2 prefixes went to 1 carrier. 2 prefixes (22%) 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.

Ste-Anne-des-Plaines’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 Videotron Ltd. in 2004. The most recent arrivals are Fibernetics Corporation (2022), Distributel (2019) and ISP Telecom Inc. (2012), a sign that new carriers are still asking for numbers in Ste-Anne-des-Plaines.

Ste-Anne-des-Plaines has just 9 prefixes (90,000 numbers): a very small rate centre, typical of a village or rural area served by a single switching office.

Videotron Ltd. leads with 44.4% of the prefixes, but 4 competitors have set up in Ste-Anne-des-Plaines: a market where the incumbent keeps the edge without exclusivity.

Allocation is mature: only 14.3% of the dated prefixes are less than ten years old, most having been handed out in 2005–2009, and 2 prefixes go back to the undated monopoly era. New Ste-Anne-des-Plaines numbers mostly come out of blocks that were assigned long ago.

Dialling a Ste-Anne-des-Plaines number

Ste-Anne-des-Plaines is served by 2 overlaid area codes (450 and 579). A 579 number is no more “out of town” than a 450 one; from abroad, dial +1 and the full ten digits.

The numbering neighbourhood

Ste-Anne-des-Plaines shares area codes 450 and 579 with at least 20 other rate centres, including Granby, Joliette, St-Jerome, St-Hyacinthe, Longueuil, Ste-Therese, Pont-Viau and Sorel. The largest of them, Granby, holds 51 prefixes in 450 and 579; the smallest on the list, Lachute, has just 17.

What a Ste-Anne-des-Plaines number tells you

A number attached to Ste-Anne-des-Plaines tells you that its prefix was issued to a carrier for this rate centre in Quebec, most often Videotron Ltd.. It does not tell you where the handset is today: a subscriber may have ported the number to any of the 5 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 Ste-Anne-des-Plaines: code 450-205 is recorded for Videotron Ltd., so every 450-205-XXXX number (10,000 possible) descends from that assignment. “Ste-Anne-des-Plaines, Quebec” there names a rate centre, not a municipality, and several area codes overlay it.

Had a call from a Ste-Anne-des-Plaines 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.
