Toronto’s share of its area codes

Area code 416 belongs to Toronto alone: all 778 of its in-service prefixes (416-200 through 416-999) sit in this one rate centre, with no other community sharing the code. Area code 647 belongs to Toronto alone: all 778 of its in-service prefixes (647-200 through 647-999) sit in this one rate centre, with no other community sharing the code. Area code 437 belongs to Toronto alone: all 549 of its in-service prefixes (437-200 through 437-999) sit in this one rate centre, with no other community sharing the code. Area code 942 belongs to Toronto alone: all 44 of its in-service prefixes (942-200 through 942-999) sit in this one rate centre, with no other community sharing the code.

Who holds these numbers

Rogers Communications Canada Inc. (Wireless) holds the largest share at 486 prefixes, 22.6% of the total, ahead of 23 other carriers. Code by code: in 416, Bell Canada leads with 449 of 778 prefixes ahead of 17 others; in 647, Rogers Communications Canada Inc. (Wireless) leads with 194 of 778 prefixes ahead of 19 others; in 437, Rogers Communications Canada Inc. (Wireless) leads with 158 of 549 prefixes ahead of 14 others; in 942, Rogers Communications Canada Inc. (Wireless) leads with 29 of 44 prefixes ahead of 6 others. 6 carriers hold prefixes in every one of Toronto’s 4 area codes, while 6 appear in just one.

Wireless and wireline

1,215 of Toronto’s 2,149 prefixes (56.5%) are held by carriers whose registered name marks a wireless business: Rogers Communications Canada Inc. (Wireless), Bell Mobility, TELUS Mobility and Fido Solutions Inc. That makes this a mostly mobile rate centre, which is typical of recent allocations: new prefixes go overwhelmingly to cellphones. 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

Toronto’s dated assignments run from 1999 to 2026. The busiest period was 2015–2019, when 392 prefixes went to 19 carriers. 614 prefixes (29%) carry no date in the register: these are the historic pre-1999 assignments, the wireline bedrock of the rate centre. Since 2020 another 391 prefixes have been added, so the rate centre is still growing.

Toronto’s oldest prefixes, the ones the register leaves undated, belong to Bell Canada, Rogers Communications Canada Inc. (Wireless) and Bell Mobility: 8 carriers made up the landscape before competition arrived. The first dated assignment went to Zayo Canada Inc. in 1999. The most recent arrivals are Cogeco Connexion Inc. (2024), Rogers Communications Canada Inc. (2019) and FGLTEL Inc. (2019), a sign that new carriers are still asking for numbers in Toronto.

With 2,149 prefixes, Toronto has a theoretical pool of 21,490,000 numbers: metropolitan-scale capacity, where running out of free combinations is the very reason overlay area codes exist.

No single carrier dominates Toronto: the leader, Rogers Communications Canada Inc. (Wireless), holds only 22.6% of the prefixes against 23 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: 25.5% 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.

The register also shows 17 prefixes assigned but not yet in service in Toronto (Bell Mobility, Rogers Communications Canada Inc. (Wireless) and TELUS Mobility): numbers that will start showing up on call displays in the coming months.

614 undated in the register.

Dialling a Toronto number

Toronto is served by 4 overlaid area codes (416, 647, 437 and 942). A 942 number is no more “out of town” than a 416 one; from abroad, dial +1 and the full ten digits.

The numbering neighbourhood

No other rate centre uses area codes 416, 647, 437 and 942: they are Toronto-only codes. A number beginning 416 is therefore, as far as the numbering plan goes, a Toronto number, even though its current holder may be anywhere in Ontario or beyond.

What a Toronto number tells you

A number attached to Toronto tells you that its prefix was issued to a carrier for this rate centre in Ontario, most often Rogers Communications Canada Inc. (Wireless). It does not tell you where the handset is today: most of Toronto’s prefixes are mobile, and a cellphone keeps its number when its owner moves across the country. 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 Toronto: code 416-219 is recorded for Rogers Communications Canada Inc. (Wireless), so every 416-219-XXXX number (10,000 possible) descends from that assignment. “Toronto, Ontario” there names a rate centre, not a municipality, and several area codes overlay it.

Had a call from a Toronto number?

Most verdicts and reports on these numbers describe scam attempts, so treat an unexpected call as a possible scam.

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. 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.
