Tweed’s share of its area codes

Within area code 343, Tweed accounts for only 7 of 641 prefixes (1.1%): the code is dominated by Ottawa-Hull and spread over 116 rate centres. Within area code 613, Tweed 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

TELUS Integrated Communications holds the largest share at 2 prefixes, 25.0% of the total, ahead of 6 other carriers. Code by code: in 343, TELUS Integrated Communications leads with 2 of 7 prefixes ahead of 5 others; Bell Canada is the only holder in 613. No carrier holds prefixes in every one of Tweed’s 2 area codes, while 7 appear in just one.

Wireless and wireline

None of Tweed’s holders carries a mobility brand in its registered name: all 8 prefixes belong to wireline or wholesale carriers, among them TELUS Integrated Communications, Bell Canada, Distributel and Fibernetics Corporation. A call showing a Tweed number therefore nominally comes from a landline, cable or VoIP platform rather than a locally assigned cellphone.

How the allocation was built up

Tweed’s dated assignments run from 2017 to 2022. The busiest period was 2020–2024, when 4 prefixes went to 4 carriers. 1 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 4 prefixes have been added, so the rate centre is still growing.

Tweed’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 2017. The most recent arrivals are Distributel (2022), TekSavvy Solutions Inc (2021) and Fibernetics Corporation (2020), a sign that new carriers are still asking for numbers in Tweed.

Tweed has just 8 prefixes (80,000 numbers): a very small rate centre, typical of a village or rural area served by a single switching office.

No single carrier dominates Tweed: the leader, TELUS Integrated Communications, holds only 25.0% 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: 57.1% of the dated prefixes were assigned in the last ten years, peaking in 2020–2024. Tweed is among the rate centres where demand for numbers is still rising quickly.

Dialling a Tweed number

Tweed is served by 2 overlaid area codes (343 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

Tweed shares area codes 343 and 613 with at least 20 other rate centres, including Ottawa-Hull, Kingston, Belleville, Cornwall, Kanata-Stittsville, Brockville, Smiths Falls and Bancroft. The largest of them, Ottawa-Hull, holds 425 prefixes in 343 and 613; the smallest on the list, Brighton, has just 10.

What a Tweed number tells you

A number attached to Tweed tells you that its prefix was issued to a carrier for this rate centre in Ontario, most often TELUS Integrated Communications. 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 Tweed: code 343-234 is recorded for TELUS Integrated Communications, so every 343-234-XXXX number (10,000 possible) descends from that assignment. “Tweed, Ontario” there names a rate centre, not a municipality, and several area codes overlay it.
