Who holds these numbers

Bell Canada holds the largest share at 29 prefixes, 25.0% of the total, ahead of 19 other carriers. Code by code: in 905, Bell Canada leads with 28 of 48 prefixes ahead of 7 others; in 289, Iristel Inc. leads with 4 of 30 prefixes ahead of 14 others; in 365, Iristel Inc. leads with 6 of 27 prefixes ahead of 12 others; in 742, Bell Mobility leads with 4 of 11 prefixes ahead of 5 others. 1 carrier holds prefixes in every one of Brampton’s 4 area codes, while 6 appear in just one.

Wireless and wireline

29 of Brampton’s 116 prefixes (25.0%) are held by carriers whose registered name marks a wireless business: Bell Mobility, TELUS Mobility, Fido Solutions Inc and Rogers Communications Canada Inc. (Wireless). Wireline prefixes still outnumber them, carried by Bell Canada, Rogers Communications Canada Inc. (Cable), Iristel Inc and Fibernetics Corporation. 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

Brampton’s dated assignments run from 1999 to 2025. The busiest period was 2020–2024, when 23 prefixes went to 12 carriers. 28 prefixes (24%) carry no date in the register: these are the historic pre-1999 assignments, the wireline bedrock of the rate centre. Since 2020 another 27 prefixes have been added, so the rate centre is still growing.

Brampton’s oldest prefixes, the ones the register leaves undated, belong to Bell Canada, Fido Solutions Inc and Rogers Communications Canada Inc. (Cable): these carriers made up the landscape before competition arrived. The first dated assignment went to Fido Solutions Inc. in 1999. The most recent arrivals are FGLTEL Inc. (2022), Beanfield Technologies Inc. (2021) and TekSavvy Solutions Inc (2020), a sign that new carriers are still asking for numbers in Brampton.

Its 116 prefixes stand for 1,160,000 possible numbers: Brampton is a large rate centre, the kind that hosts several switching offices and a sizeable business clientele.

No single carrier dominates Brampton: the leader, Bell Canada, holds only 25.0% of the prefixes against 19 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: 30.7% of the dated prefixes go back to the last ten years, the most active period being 2020–2024. The rate centre is growing at a regular rather than explosive pace.

Dialling a Brampton number

Brampton 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

Brampton shares area codes 905, 289, 365 and 742 with at least 20 other rate centres, including Hamilton, Oshawa, St. Catharines-Thorold, Oakville, Markham, Ajax-Pickering, Cooksville and Thornhill. 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 Brampton number tells you

A number attached to Brampton 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 20 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 Brampton: code 905-450 is recorded for Bell Canada, so every 905-450-XXXX number (10,000 possible) descends from that assignment. “Brampton, Ontario” there names a rate centre, not a municipality, and several area codes overlay it.

Had a call from a Brampton 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.
