Courtright’s share of its area codes

Within area code 226, Courtright accounts for only 3 of 778 prefixes (0.4%): the code is dominated by London and spread over 166 rate centres. Within area code 519, Courtright accounts for only 2 of 779 prefixes (0.3%): the code is dominated by London and spread over 210 rate centres. Within area code 548, Courtright accounts for only 2 of 499 prefixes (0.4%): the code is dominated by London and spread over 170 rate centres.

Who holds these numbers

Bell Canada holds the largest share at 2 prefixes, 28.6% of the total, ahead of 5 other carriers. Code by code: in 226, Distributel leads with 1 of 3 prefixes ahead of 2 others; Bell Canada is the only holder in 519; in 548, Fibernetics Corporation leads with 1 of 2 prefixes ahead of 1 others. No carrier holds prefixes in every one of Courtright’s 3 area codes, while 6 appear in just one.

Wireless and wireline

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

How the allocation was built up

Courtright’s dated assignments run from 2007 to 2022. The busiest period was 2020–2024, when 2 prefixes went to 2 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 2 prefixes have been added, so the rate centre is still growing.

Courtright’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 Execulink Telecom Inc. in 2007. The most recent arrivals are Fibernetics Corporation (2022), ISP Telecom Inc. (2022) and Distributel (2018), a sign that new carriers are still asking for numbers in Courtright.

Courtright 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 Courtright: the leader, Bell Canada, holds only 28.6% 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.

Demand remains steady: 40.0% 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 Courtright number

Courtright is served by 3 overlaid area codes (226, 519 and 548). A 548 number is no more “out of town” than a 226 one; from abroad, dial +1 and the full ten digits.

The numbering neighbourhood

Courtright shares area codes 226, 519 and 548 with at least 20 other rate centres, including London, Kitchener-Waterloo, Windsor, Guelph, Brantford, Sarnia, Chatham and Hespeler. The largest of them, London, holds 214 prefixes in 226, 519 and 548; the smallest on the list, Essex, has just 16.

What a Courtright number tells you

A number attached to Courtright 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 Courtright: code 519-431 is recorded for Bell Canada, so every 519-431-XXXX number (10,000 possible) descends from that assignment. “Courtright, Ontario” there names a rate centre, not a municipality, and several area codes overlay it.
