Girardville’s share of its area codes

Within area code 367, Girardville accounts for only 2 of 233 prefixes (0.9%): the code is dominated by Quebec and spread over 111 rate centres. Within area code 581, Girardville accounts for only 2 of 778 prefixes (0.3%): the code is dominated by Quebec and spread over 232 rate centres. Within area code 418, Girardville accounts for only 1 of 777 prefixes (0.1%): the code is dominated by Quebec and spread over 258 rate centres.

Who holds these numbers

Bell Canada holds the largest share at 1 prefixes, 20.0% of the total, ahead of 4 other carriers. Code by code: in 367, ISP Telecom Inc. leads with 1 of 2 prefixes ahead of 1 others; in 581, Telecommunications Xittel Inc leads with 1 of 2 prefixes ahead of 1 others; Bell Canada is the only holder in 418. No carrier holds prefixes in every one of Girardville’s 3 area codes, while 5 appear in just one.

Wireless and wireline

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

How the allocation was built up

Girardville’s dated assignments run from 2012 to 2025. The busiest period was 2010–2014, when 2 prefixes went to 2 carriers. 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 2 prefixes have been added, so the rate centre is still growing.

Girardville’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 Telecommunications Xittel Inc in 2012. The most recent arrivals are TELUS Quebec (2025), ISP Telecom Inc. (2023) and Videotron Ltd. (2014), a sign that new carriers are still asking for numbers in Girardville.

Girardville 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.

No single carrier dominates Girardville: the leader, Bell Canada, holds only 20.0% of the prefixes against 4 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 2010–2014. Girardville is among the rate centres where demand for numbers is still rising quickly.

Dialling a Girardville number

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

The numbering neighbourhood

Girardville shares area codes 367, 581 and 418 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 Girardville number tells you

A number attached to Girardville 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 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 Girardville: code 418-258 is recorded for Bell Canada, so every 418-258-XXXX number (10,000 possible) descends from that assignment. “Girardville, Quebec” there names a rate centre, not a municipality, and several area codes overlay it.

Had a call from a Girardville 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.
