Wireless and wireline

None of St-Aime’s holders carries a mobility brand in its registered name: all 3 prefixes belong to wireline or wholesale carriers, among them Cooptel, TELUS Quebec and Telebec Ltee. A call showing a St-Aime number therefore nominally comes from a landline, cable or VoIP platform rather than a locally assigned cellphone.

How the allocation was built up

St-Aime’s dated assignments run from 2018 to 2021. The busiest period was 2015–2019, when 1 prefixes went to 1 carrier. 1 prefixes (33%) carry no date in the register: these are the historic pre-1999 assignments, the wireline bedrock of the rate centre. Since 2020 another 1 prefixes have been added, so the rate centre is still growing.

St-Aime’s oldest prefixes, the ones the register leaves undated, belong to Telebec Ltee: this carrier made up the landscape before competition arrived. The first dated assignment went to Cooptel in 2018. The most recent arrivals are TELUS Quebec (2021) and Cooptel (2018), a sign that new carriers are still asking for numbers in St-Aime.

St-Aime has just 3 prefixes (30,000 numbers): a very small rate centre, typical of a village or rural area served by a single switching office.

No single carrier dominates St-Aime: the leader, Cooptel, holds only 33.3% of the prefixes against 2 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: 50.0% of the dated prefixes were assigned in the last ten years, peaking in 2015–2019. St-Aime is among the rate centres where demand for numbers is still rising quickly.

What a St-Aime number tells you

A number attached to St-Aime tells you that its prefix was issued to a carrier for this rate centre in Quebec, most often Cooptel. It does not tell you where the handset is today: a subscriber may have ported the number to any of the 3 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.

Reading a register entry for St-Aime: code 579-445 is recorded for Cooptel, so every 579-445-XXXX number (10,000 possible) descends from that assignment. “St-Aime, Quebec” there names a rate centre, not a municipality, and several area codes overlay it.

Allocation source: Canadian Numbering Administrator (CNAC), the registry that records which carrier a central-office code was originally issued to. 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.
