Code by code: in 581, Videotron Ltd. leads with 2 of 3 prefixes ahead of 1 others; Sogetel Inc. is the only holder in 418.

| Carrier | 581 | 418 | Total |

| Sogetel Inc. | — | 1 | 1 |
| TELUS Quebec | 1 | — | 1 |
Wireless and wireline
None of Sainte-Rose’s holders carries a mobility brand in its registered name: all 4 prefixes belong to wireline or wholesale carriers, among them Videotron Ltd, Sogetel Inc and TELUS Quebec. A call showing a Sainte-Rose number therefore nominally comes from a landline, cable or VoIP platform rather than a locally assigned cellphone.
How the allocation was built up
Sainte-Rose’s dated assignments run from 2012 to 2018. The busiest period was 2015–2019, when 2 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. No prefix has been added since 2020: demand for numbers in Sainte-Rose is flat.
Sainte-Rose’s oldest prefixes, the ones the register leaves undated, belong to Sogetel Inc: this carrier made up the landscape before competition arrived. The first dated assignment went to TELUS Quebec in 2012. The most recent arrivals are Videotron Ltd. (2016) and TELUS Quebec (2012), a sign that new carriers are still asking for numbers in Sainte-Rose.
Sainte-Rose has just 4 prefixes (40,000 numbers): a very small rate centre, typical of a village or rural area served by a single switching office.
Videotron Ltd. leads with 50.0% of the prefixes, but 2 competitors have set up in Sainte-Rose: a market where the incumbent keeps the edge without exclusivity.
Allocation is mature: only 0.0% of the dated prefixes are less than ten years old, most having been handed out in 2015–2019, and 1 prefixes go back to the undated monopoly era. New Sainte-Rose numbers mostly come out of blocks that were assigned long ago.
| Period | Prefixes | Carriers |
|---|---|---|
| 2010–2014 | 1 | 1 |
| 2015–2019 | 2 | 1 |

What a Sainte-Rose number tells you
A number attached to Sainte-Rose tells you that its prefix was issued to a carrier for this rate centre in Quebec, most often Videotron Ltd.. 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 Sainte-Rose: code 581-770 is recorded for Videotron Ltd., so every 581-770-XXXX number (10,000 possible) descends from that assignment. “Sainte-Rose, Quebec” there names a rate centre, not a municipality, and several area codes overlay it.

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.
