Madoc’s share of its area codes

Within area code 343, Madoc 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 613, Madoc accounts for only 2 of 772 prefixes (0.3%): 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, Distributel leads with 1 of 5 prefixes ahead of 4 others; in 613, Bell Canada leads with 1 of 2 prefixes ahead of 1 others. No carrier holds prefixes in every one of Madoc’s 2 area codes, while 7 appear in just one.

Wireless and wireline

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

How the allocation was built up

Madoc’s dated assignments run from 2013 to 2022. The busiest period was 2015–2019, when 3 prefixes went to 3 carriers. 1 prefixes (14%) carry no date in the register: these are the historic pre-1999 assignments, the wireline bedrock of the rate centre. Since 2020 another 2 prefixes have been added, so the rate centre is still growing.

Madoc’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 Fibernetics Corporation in 2013. The most recent arrivals are Distributel (2022), TekSavvy Solutions Inc (2021) and Nexicom Telecommunications Inc (2018), a sign that new carriers are still asking for numbers in Madoc.

Madoc 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 Madoc: 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.

Demand remains steady: 33.3% of the dated prefixes go back to the last ten years, the most active period being 2015–2019. The rate centre is growing at a regular rather than explosive pace.

Dialling a Madoc number

Madoc 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

Madoc 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 Madoc number tells you

A number attached to Madoc 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 Madoc: code 613-473 is recorded for Bell Canada, so every 613-473-XXXX number (10,000 possible) descends from that assignment. “Madoc, Ontario” there names a rate centre, not a municipality, and several area codes overlay it.
