Who holds these numbers

Bell Canada holds the largest share at 16 prefixes, 32.7% of the total, ahead of 17 other carriers. Code by code: in 905, Bell Canada leads with 15 of 26 prefixes ahead of 4 others; in 289, Fibernetics Corporation leads with 2 of 14 prefixes ahead of 9 others; in 365, Fibernetics Corporation leads with 2 of 7 prefixes ahead of 5 others; in 742, Cogeco Connexion Inc. leads with 1 of 2 prefixes ahead of 1 others. No carrier holds prefixes in every one of Malton’s 4 area codes, while 13 appear in just one.

Wireless and wireline

2 of Malton’s 49 prefixes (4.1%) are held by carriers whose registered name marks a wireless business: Fido Solutions Inc. Wireline prefixes still outnumber them, carried by Bell Canada, Rogers Communications Canada Inc. (Cable), Fibernetics Corporation and TELUS Integrated Communications. 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

Malton’s dated assignments run from 1999 to 2025. The busiest period was 2000–2004, when 10 prefixes went to 5 carriers. 15 prefixes (31%) carry no date in the register: these are the historic pre-1999 assignments, the wireline bedrock of the rate centre. Since 2020 another 7 prefixes have been added, so the rate centre is still growing.

Malton’s oldest prefixes, the ones the register leaves undated, belong to Bell Canada, Rogers Communications Canada Inc. (Cable) and Zayo Canada Inc: these carriers made up the landscape before competition arrived. The first dated assignment went to Rogers Communications Canada Inc. (Cable) in 1999. The most recent arrivals are Cogeco Connexion Inc. (2025), FGLTEL Inc. (2022) and Beanfield Technologies Inc. (2021), a sign that new carriers are still asking for numbers in Malton.

Malton’s 49 prefixes provide 490,000 numbers, which corresponds to a mid-sized city or a well-established suburb that every major carrier wants a slice of.

No single carrier dominates Malton: the leader, Bell Canada, holds only 32.7% of the prefixes against 17 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: 20.6% of the dated prefixes go back to the last ten years, the most active period being 2000–2004. The rate centre is growing at a regular rather than explosive pace.

Dialling a Malton number

Malton is served by 4 overlaid area codes (905, 289, 365 and 742). A 742 number is no more “out of town” than a 905 one; from abroad, dial +1 and the full ten digits.

The numbering neighbourhood

Malton shares area codes 905, 289, 365 and 742 with at least 20 other rate centres, including Hamilton, Brampton, Oshawa, St. Catharines-Thorold, Oakville, Markham, Ajax-Pickering and Cooksville. The largest of them, Hamilton, holds 222 prefixes in 289, 365, 742 and 905; the smallest on the list, Maple, has just 28.

What a Malton number tells you

A number attached to Malton tells you that its prefix was issued to a carrier for this rate centre in Ontario, 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 18 carriers present here or to a VoIP service usable anywhere. Nor does it tell you who is calling: caller ID can be spoofed, and an Ontario area code is easy to borrow to look local.

Reading a register entry for Malton: code 905-293 is recorded for Bell Canada, so every 905-293-XXXX number (10,000 possible) descends from that assignment. “Malton, Ontario” there names a rate centre, not a municipality, and several area codes overlay it.

Had a call from a Malton 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.

   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.
