Wireless and wireline
None of St-Malo’s holders carries a mobility brand in its registered name: all 8 prefixes belong to wireline or wholesale carriers, among them Videotron Ltd, Bell Canada, Distributel and Fibernetics Corporation. A call showing a St-Malo number therefore nominally comes from a landline, cable or VoIP platform rather than a locally assigned cellphone.
How the allocation was built up
St-Malo’s dated assignments run from 2011 to 2025. The busiest period was 2015–2019, when 2 prefixes went to 2 carriers. 2 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 3 prefixes have been added, so the rate centre is still growing.
St-Malo’s oldest prefixes, the ones the register leaves undated, belong to Bell Canada and MTS Inc: these carriers made up the landscape before competition arrived. The first dated assignment went to Videotron Ltd. in 2011. The most recent arrivals are TELUS Quebec (2025), IXICA Communications Inc. (2021) and Fibernetics Corporation (2021), a sign that new carriers are still asking for numbers in St-Malo.
St-Malo 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-Malo: the leader, Videotron Ltd., 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.
Growth is recent: 50.0% of the dated prefixes were assigned in the last ten years, peaking in 2015–2019. St-Malo is among the rate centres where demand for numbers is still rising quickly.
| Period | Prefixes | Carriers |

| 2015–2019 | 2 | 2 |

What a St-Malo number tells you
A number attached to St-Malo 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 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.
Reading a register entry for St-Malo: code 873-547 is recorded for Videotron Ltd., so every 873-547-XXXX number (10,000 possible) descends from that assignment. “St-Malo, 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.
