Who holds these numbers

Iristel Inc. holds the largest share at 5 prefixes, 31.3% of the total, ahead of 8 other carriers. Code by code: in 226, Iristel Inc. leads with 2 of 5 prefixes ahead of 3 others; in 548, Iristel Inc. leads with 1 of 5 prefixes ahead of 4 others; Iristel Inc. is the only holder in 382; in 519, Bell Canada leads with 1 of 2 prefixes ahead of 1 others; Navigata Communications Limited is the only holder in 236; TELUS is the only holder in 250. No carrier holds prefixes in every one of Clinton’s 6 area codes, while 5 appear in just one.

Wireless and wireline

None of Clinton’s holders carries a mobility brand in its registered name: all 16 prefixes belong to wireline or wholesale carriers, among them Iristel Inc, Bell Canada, Bragg Communications Inc and Fibernetics Corporation. A call showing a Clinton number therefore nominally comes from a landline, cable or VoIP platform rather than a locally assigned cellphone.

How the allocation was built up

Clinton’s dated assignments run from 2006 to 2026. The busiest period was 2020–2024, when 5 prefixes went to 3 carriers. 2 prefixes (13%) 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.

Clinton’s oldest prefixes, the ones the register leaves undated, belong to TELUS and Bell Canada: these carriers made up the landscape before competition arrived. The first dated assignment went to Tuckersmith Communications Co-operative Ltd. in 2006. The most recent arrivals are Distributel (2022), Bell Canada (2016) and Navigata Communications Limited (2016), a sign that new carriers are still asking for numbers in Clinton.

Clinton has only 16 prefixes, or 160,000 numbers: a small rate centre, where the arrival of a single new carrier visibly changes the landscape.

No single carrier dominates Clinton: the leader, Iristel Inc., holds only 31.3% of the prefixes against 8 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: 42.9% 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 Clinton number

Clinton is served by 6 overlaid area codes (226, 548, 382, 519, 236 and 250). A 250 number is no more “out of town” than a 226 one; from abroad, dial +1 and the full ten digits.

The numbering neighbourhood

Clinton shares area codes 226, 548, 382, 519, 236 and 250 with at least 20 other rate centres, including London, Kitchener-Waterloo, Vancouver, Windsor, Victoria, Guelph, Brantford and Chatham. The largest of them, London, holds 217 prefixes in 226, 382, 519 and 548; the smallest on the list, Vernon, has just 26.

What a Clinton number tells you

A number attached to Clinton tells you that its prefix was issued to a carrier for this rate centre in Ontario, most often Iristel Inc.. It does not tell you where the handset is today: a subscriber may have ported the number to any of the 9 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 Clinton: code 226-455 is recorded for Iristel Inc., so every 226-455-XXXX number (10,000 possible) descends from that assignment. “Clinton, Ontario” there names a rate centre, not a municipality, and several area codes overlay it.
