Ville-Marie’s share of its area codes

Within area code 873, Ville-Marie accounts for only 8 of 667 prefixes (1.2%): the code is dominated by Sherbrooke and spread over 162 rate centres. Within area code 819, Ville-Marie accounts for only 4 of 770 prefixes (0.5%): the code is dominated by Ottawa-Hull and spread over 211 rate centres.

Who holds these numbers

Iristel Inc. holds the largest share at 3 prefixes, 25.0% of the total, ahead of 6 other carriers. Code by code: in 873, Iristel Inc. leads with 3 of 8 prefixes ahead of 5 others; in 819, Telebec Ltee. leads with 2 of 4 prefixes ahead of 2 others. 2 carriers hold prefixes in every one of Ville-Marie’s 2 area codes, while 5 appear in just one.

Wireless and wireline

4 of Ville-Marie’s 12 prefixes (33.3%) are held by carriers whose registered name marks a wireless business: Bell Mobility, Rogers Communications Canada Inc. (Wireless) and TELUS Mobility. Wireline prefixes still outnumber them, carried by Iristel Inc, ISP Telecom Inc, Telebec Ltee and TELUS Quebec. 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

Ville-Marie’s dated assignments run from 2013 to 2025. The busiest period was 2015–2019, when 5 prefixes went to 4 carriers. 2 prefixes (17%) 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.

Ville-Marie’s oldest prefixes, the ones the register leaves undated, belong to Telebec Ltee: this carrier made up the landscape before competition arrived. The first dated assignment went to ISP Telecom Inc. in 2013. The most recent arrivals are Rogers Communications Canada Inc. (Wireless) (2021), TELUS Mobility (2016) and Iristel Inc. (2016), a sign that new carriers are still asking for numbers in Ville-Marie.

Ville-Marie has only 12 prefixes, or 120,000 numbers: a small rate centre, where the arrival of a single new carrier visibly changes the landscape.

No single carrier dominates Ville-Marie: the leader, Iristel Inc., holds only 25.0% of the prefixes against 6 competitors, a sign of a highly fragmented market where cable companies, mobility brands and VoIP providers weigh as much as the incumbent.

Demand remains steady: 20.0% of the dated prefixes go back to the last ten years, the most active period being 2015–2019. The rate centre is growing at a regular rather than explosive pace.

Dialling a Ville-Marie number

Ville-Marie is served by 2 overlaid area codes (873 and 819). A 819 number is no more “out of town” than a 873 one; from abroad, dial +1 and the full ten digits.

The numbering neighbourhood

Ville-Marie shares area codes 873 and 819 with at least 20 other rate centres, including Ottawa-Hull, Sherbrooke, Trois-Rivieres, Drummondville, Gatineau, Victoriaville, Val-D'Or and Maniwaki. The largest of them, Ottawa-Hull, holds 119 prefixes in 819 and 873; the smallest on the list, Plessisville, has just 11.

What a Ville-Marie number tells you

A number attached to Ville-Marie tells you that its prefix was issued to a carrier for this rate centre in Quebec, most often Iristel Inc.. It does not tell you where the handset is today: a subscriber may have ported the number to any of the 7 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 Ville-Marie: code 873-301 is recorded for Iristel Inc., so every 873-301-XXXX number (10,000 possible) descends from that assignment. “Ville-Marie, Quebec” there names a rate centre, not a municipality, and several area codes overlay it.

Had a call from a Ville-Marie 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.
