Arden’s share of its area codes

Within area code 343, Arden accounts for only 5 of 641 prefixes (0.8%): the code is dominated by Ottawa-Hull and spread over 116 rate centres. Within area code 204, Arden accounts for only 1 of 781 prefixes (0.1%): the code is dominated by Winnipeg and spread over 245 rate centres. Within area code 613, Arden accounts for only 1 of 772 prefixes (0.1%): the code is dominated by Ottawa-Hull and spread over 132 rate centres.

Who holds these numbers

Bell Canada holds the largest share at 1 prefixes, 14.3% of the total, ahead of 6 other carriers. Code by code: in 343, Comwave Networks leads with 1 of 5 prefixes ahead of 4 others; MTS Inc. is the only holder in 204; Bell Canada is the only holder in 613. No carrier holds prefixes in every one of Arden’s 3 area codes, while 7 appear in just one.

Wireless and wireline

None of Arden’s holders carries a mobility brand in its registered name: all 7 prefixes belong to wireline or wholesale carriers, among them Bell Canada, Comwave Networks, Fibernetics Corporation and ISP Telecom Inc. A call showing a Arden number therefore nominally comes from a landline, cable or VoIP platform rather than a locally assigned cellphone.

How the allocation was built up

Arden’s dated assignments run from 2013 to 2021. The busiest period was 2020–2024, when 3 prefixes went to 3 carriers. 2 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 3 prefixes have been added, so the rate centre is still growing.

Arden’s oldest prefixes, the ones the register leaves undated, belong to Bell Canada and MTS Inc: these carriers made up the landscape before competition arrived. The first dated assignment went to Comwave Networks in 2013. The most recent arrivals are Fibernetics Corporation (2021), TekSavvy Solutions Inc (2021) and ISP Telecom Inc. (2020), a sign that new carriers are still asking for numbers in Arden.

Arden has just 7 prefixes (70,000 numbers): a very small rate centre, typical of a village or rural area served by a single switching office.

No single carrier dominates Arden: the leader, Bell Canada, holds only 14.3% of the prefixes against 6 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. Arden is among the rate centres where demand for numbers is still rising quickly.

Dialling a Arden number

Arden is served by 3 overlaid area codes (343, 204 and 613). A 613 number is no more “out of town” than a 343 one; from abroad, dial +1 and the full ten digits.

The numbering neighbourhood

Arden shares area codes 343, 204 and 613 with at least 20 other rate centres, including Ottawa-Hull, Winnipeg, Kingston, Belleville, Cornwall, Kanata-Stittsville, Brockville and Brandon. The largest of them, Ottawa-Hull, holds 425 prefixes in 343 and 613; the smallest on the list, Picton, has just 13.

What a Arden number tells you

A number attached to Arden 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 7 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 Arden: code 613-335 is recorded for Bell Canada, so every 613-335-XXXX number (10,000 possible) descends from that assignment. “Arden, Ontario” there names a rate centre, not a municipality, and several area codes overlay it.

Every Arden prefix

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