Mirabel-Aeroport’s share of its area codes

Within area code 579, Mirabel-Aeroport accounts for only 5 of 644 prefixes (0.8%): the code is dominated by Granby and spread over 126 rate centres. Within area code 450, Mirabel-Aeroport accounts for only 3 of 775 prefixes (0.4%): the code is dominated by Granby and spread over 129 rate centres.

Who holds these numbers

TELUS Quebec holds the largest share at 2 prefixes, 25.0% of the total, ahead of 5 other carriers. Code by code: in 579, TELUS Quebec leads with 1 of 5 prefixes ahead of 4 others; in 450, TELUS Quebec leads with 1 of 3 prefixes ahead of 2 others. 2 carriers hold prefixes in every one of Mirabel-Aeroport’s 2 area codes, while 4 appear in just one.

Wireless and wireline

None of Mirabel-Aeroport’s holders carries a mobility brand in its registered name: all 8 prefixes belong to wireline or wholesale carriers, among them TELUS Quebec, Videotron Ltd, Bell Canada and Distributel. A call showing a Mirabel-Aeroport number therefore nominally comes from a landline, cable or VoIP platform rather than a locally assigned cellphone.

How the allocation was built up

Mirabel-Aeroport’s dated assignments run from 2002 to 2022. The busiest period was 2015–2019, when 3 prefixes went to 3 carriers. 1 prefixes (13%) 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.

Mirabel-Aeroport’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 2002. 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 Mirabel-Aeroport.

Mirabel-Aeroport has just 8 prefixes (80,000 numbers): a very small rate centre, typical of a village or rural area served by a single switching office.

No single carrier dominates Mirabel-Aeroport: the leader, TELUS Quebec, holds only 25.0% of the prefixes against 5 competitors, a sign of a highly fragmented market where cable companies, mobility brands and VoIP providers weigh as much as the incumbent.

Allocation is mature: only 14.3% of the dated prefixes are less than ten years old, most having been handed out in 2015–2019, and 1 prefixes go back to the undated monopoly era. New Mirabel-Aeroport numbers mostly come out of blocks that were assigned long ago.

Dialling a Mirabel-Aeroport number

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

The numbering neighbourhood

Mirabel-Aeroport shares area codes 579 and 450 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 Mirabel-Aeroport number tells you

A number attached to Mirabel-Aeroport tells you that its prefix was issued to a carrier for this rate centre in Quebec, most often TELUS Quebec. It does not tell you where the handset is today: a subscriber may have ported the number to any of the 6 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 Mirabel-Aeroport: code 579-254 is recorded for TELUS Quebec, so every 579-254-XXXX number (10,000 possible) descends from that assignment. “Mirabel-Aeroport, Quebec” there names a rate centre, not a municipality, and several area codes overlay it.

Had a call from a Mirabel-Aeroport 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.
