Who holds these numbers

TELUS Quebec holds the largest share at 2 prefixes, 25.0% of the total, ahead of 6 other carriers. Code by code: in 579, TELUS Quebec leads with 2 of 5 prefixes ahead of 3 others; in 450, Bell Canada leads with 1 of 3 prefixes ahead of 2 others. No carrier holds prefixes in every one of St-Alphonse-de-Rodriguez’s 2 area codes, while 7 appear in just one.

Wireless and wireline

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

How the allocation was built up

St-Alphonse-de-Rodriguez’s dated assignments run from 2005 to 2022. The busiest period was 2015–2019, when 3 prefixes went to 3 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 2 prefixes have been added, so the rate centre is still growing.

St-Alphonse-de-Rodriguez’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 Videotron Ltd. in 2005. The most recent arrivals are Fibernetics Corporation (2021), Cooptel (2019) and TELUS Quebec (2018), a sign that new carriers are still asking for numbers in St-Alphonse-de-Rodriguez.

St-Alphonse-de-Rodriguez 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 St-Alphonse-de-Rodriguez: the leader, TELUS Quebec, 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.

Demand remains steady: 28.6% 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.

What a St-Alphonse-de-Rodriguez number tells you

A number attached to St-Alphonse-de-Rodriguez tells you that its prefix was issued to a carrier for this rate centre in Quebec, most often TELUS Quebec. 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 a Quebec area code is easy to borrow to look local.

An allocation says who was issued the prefix, not who serves the number today: numbers can be ported between carriers, and caller ID can be spoofed outright.
