Wireless and wireline

None of Riviere-au-Renard’s holders carries a mobility brand in its registered name: all 4 prefixes belong to wireline or wholesale carriers, among them TELUS Quebec and Bell Canada. A call showing a Riviere-au-Renard number therefore nominally comes from a landline, cable or VoIP platform rather than a locally assigned cellphone.

How the allocation was built up

The busiest period was 2010–2014, when 1 prefixes went to 1 carrier. 1 prefixes (25%) 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.

Riviere-au-Renard’s oldest prefixes, the ones the register leaves undated, belong to TELUS Quebec: this carrier made up the landscape before competition arrived.

Demand remains steady: 33.3% of the dated prefixes go back to the last ten years, the most active period being 2010–2014. The rate centre is growing at a regular rather than explosive pace.

What a Riviere-au-Renard number tells you

A number attached to Riviere-au-Renard 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 2 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.
