Who holds these numbers

Bell Canada holds the largest share at 11 prefixes, 30.6% of the total, ahead of 12 other carriers. Code by code: in 289, Iristel Inc. leads with 3 of 13 prefixes ahead of 6 others; Bell Canada is the only holder in 905; in 365, Iristel Inc. leads with 2 of 9 prefixes ahead of 7 others; in 742, Fibernetics Corporation leads with 1 of 3 prefixes ahead of 2 others. No carrier holds prefixes in every one of Niagara Falls’s 4 area codes, while 8 appear in just one.

Wireless and wireline

3 of Niagara Falls’s 36 prefixes (8.3%) are held by carriers whose registered name marks a wireless business: Bell Mobility. Wireline prefixes still outnumber them, carried by Bell Canada, Iristel Inc, 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

Niagara Falls’s dated assignments run from 2004 to 2024. The busiest period was 2005–2009, when 9 prefixes went to 7 carriers. 10 prefixes (28%) carry no date in the register: these are the historic pre-1999 assignments, the wireline bedrock of the rate centre. Since 2020 another 8 prefixes have been added, so the rate centre is still growing.

Niagara Falls’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 Bell Canada in 2004. The most recent arrivals are TekSavvy Solutions Inc (2020), IXICA Communications Inc. (2020) and Distributel (2018), a sign that new carriers are still asking for numbers in Niagara Falls.

Niagara Falls’s 36 prefixes provide 360,000 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 Niagara Falls: the leader, Bell Canada, holds only 30.6% 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: 30.8% of the dated prefixes go back to the last ten years, the most active period being 2005–2009. The rate centre is growing at a regular rather than explosive pace.

What a Niagara Falls number tells you

A number attached to Niagara Falls 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 Niagara Falls: code 905-262 is recorded for Bell Canada, so every 905-262-XXXX number (10,000 possible) descends from that assignment. “Niagara Falls, Ontario” there names a rate centre, not a municipality, and several area codes overlay it.

An allocation says who was issued the prefix, not who serves the number today: numbers can be ported between carriers, and caller ID can be spoofed outright.
