Stevensville’s share of its area codes

Within area code 365, Stevensville accounts for only 4 of 702 prefixes (0.6%): the code is dominated by Markham and spread over 88 rate centres. Within area code 289, Stevensville accounts for only 1 of 772 prefixes (0.1%): the code is dominated by Hamilton and spread over 87 rate centres. Within area code 905, Stevensville accounts for only 1 of 773 prefixes (0.1%): the code is dominated by Hamilton and spread over 94 rate centres.

Who holds these numbers

Bell Canada holds the largest share at 1 prefixes, 16.7% of the total, ahead of 5 other carriers. Code by code: in 365, Distributel leads with 1 of 4 prefixes ahead of 3 others; TELUS Integrated Communications is the only holder in 289; Bell Canada is the only holder in 905. No carrier holds prefixes in every one of Stevensville’s 3 area codes, while 6 appear in just one.

Wireless and wireline

None of Stevensville’s holders carries a mobility brand in its registered name: all 6 prefixes belong to wireline or wholesale carriers, among them Bell Canada, Distributel, Fibernetics Corporation and ISP Telecom Inc. A call showing a Stevensville number therefore nominally comes from a landline, cable or VoIP platform rather than a locally assigned cellphone.

How the allocation was built up

Stevensville’s dated assignments run from 2007 to 2023. The busiest period was 2020–2024, when 3 prefixes went to 3 carriers. 1 prefixes (17%) carry no date in the register: these are the historic pre-1999 assignments, the wireline bedrock of the rate centre. Since 2020 another 3 prefixes have been added, so the rate centre is still growing.

Stevensville’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 TELUS Integrated Communications in 2007. The most recent arrivals are ISP Telecom Inc. (2023), Fibernetics Corporation (2022) and TekSavvy Solutions Inc (2020), a sign that new carriers are still asking for numbers in Stevensville.

Stevensville has just 6 prefixes (60,000 numbers): a very small rate centre, typical of a village or rural area served by a single switching office.

No single carrier dominates Stevensville: the leader, Bell Canada, holds only 16.7% of the prefixes against 5 competitors, a sign of a highly fragmented market where cable companies, mobility brands and VoIP providers weigh as much as the incumbent.

Growth is recent: 60.0% of the dated prefixes were assigned in the last ten years, peaking in 2020–2024. Stevensville is among the rate centres where demand for numbers is still rising quickly.

Dialling a Stevensville number

Stevensville is served by 3 overlaid area codes (365, 289 and 905). A 905 number is no more “out of town” than a 365 one; from abroad, dial +1 and the full ten digits.

The numbering neighbourhood

Stevensville shares area codes 365, 289 and 905 with at least 20 other rate centres, including Hamilton, Oshawa, Brampton, St. Catharines-Thorold, Oakville, Markham, Cooksville and Ajax-Pickering. The largest of them, Hamilton, holds 213 prefixes in 289, 365 and 905; the smallest on the list, Woodbridge, has just 28.

What a Stevensville number tells you

A number attached to Stevensville 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 6 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 Stevensville: code 905-382 is recorded for Bell Canada, so every 905-382-XXXX number (10,000 possible) descends from that assignment. “Stevensville, Ontario” there names a rate centre, not a municipality, and several area codes overlay it.
