Port Credit’s share of its area codes

Within area code 365, Port Credit accounts for only 8 of 706 prefixes (1.1%): the code is dominated by Markham and spread over 88 rate centres. Within area code 905, Port Credit accounts for only 7 of 773 prefixes (0.9%): the code is dominated by Hamilton and spread over 94 rate centres. Within area code 289, Port Credit accounts for only 6 of 772 prefixes (0.8%): the code is dominated by Hamilton and spread over 87 rate centres. Within area code 742, Port Credit accounts for only 1 of 148 prefixes (0.7%): the code is dominated by Brampton and spread over 68 rate centres.

Who holds these numbers

Bell Canada holds the largest share at 4 prefixes, 18.2% of the total, ahead of 12 other carriers. Code by code: in 365, Fibernetics Corporation leads with 3 of 8 prefixes ahead of 5 others; in 905, Bell Canada leads with 4 of 7 prefixes ahead of 1 others; in 289, Fibernetics Corporation leads with 1 of 6 prefixes ahead of 5 others; FGLTEL Inc. is the only holder in 742. No carrier holds prefixes in every one of Port Credit’s 4 area codes, while 11 appear in just one.

Wireless and wireline

1 of Port Credit’s 22 prefixes (4.5%) are held by carriers whose registered name marks a wireless business: Fido Solutions Inc. Wireline prefixes still outnumber them, carried by Bell Canada, Fibernetics Corporation, Rogers Communications Canada Inc. (Cable) and Distributel. 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

Port Credit’s dated assignments run from 2003 to 2024. The busiest period was 2020–2024, when 6 prefixes went to 4 carriers. 4 prefixes (18%) carry no date in the register: these are the historic pre-1999 assignments, the wireline bedrock of the rate centre. Since 2020 another 6 prefixes have been added, so the rate centre is still growing.

Port Credit’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 Rogers Communications Canada Inc. (Cable) in 2003. 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 Port Credit.

Port Credit has only 22 prefixes, or 220,000 numbers: a small rate centre, where the arrival of a single new carrier visibly changes the landscape.

No single carrier dominates Port Credit: the leader, Bell Canada, holds only 18.2% of the prefixes against 12 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: 33.3% 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 Port Credit number

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

The numbering neighbourhood

Port Credit shares area codes 365, 905, 289 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, Dunnville, has just 28.

What a Port Credit number tells you

A number attached to Port Credit 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 13 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 Port Credit: code 905-271 is recorded for Bell Canada, so every 905-271-XXXX number (10,000 possible) descends from that assignment. “Port Credit, Ontario” there names a rate centre, not a municipality, and several area codes overlay it.

Every Port Credit prefix

Each row is an in-service central-office code recorded for Port Credit, with its original holder and year of assignment.

Had a call from a Port Credit 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.
