Havre-aux-Maisons’s share of its area codes

Within area code 367, Havre-aux-Maisons accounts for only 2 of 233 prefixes (0.9%): the code is dominated by Quebec and spread over 111 rate centres.

Who holds these numbers

Bell Canada holds the largest share at 1 prefixes, 33.3% of the total, ahead of 2 other carriers. Code by code: in 367, Bell Canada leads with 1 of 2 prefixes ahead of 1 others; Telebec Ltee. is the only holder in 418. No carrier holds prefixes in every one of Havre-aux-Maisons’s 2 area codes, while 3 appear in just one.

Wireless and wireline

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

How the allocation was built up

Havre-aux-Maisons’s dated assignments run from 2024 to 2025. The busiest period was 2020–2024, 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 2 prefixes have been added, so the rate centre is still growing.

Havre-aux-Maisons’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 Bell Canada in 2024. The most recent arrivals are TELUS Quebec (2025) and Bell Canada (2024), a sign that new carriers are still asking for numbers in Havre-aux-Maisons.

Havre-aux-Maisons 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 Havre-aux-Maisons: the leader, Bell Canada, 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: 100.0% of the dated prefixes were assigned in the last ten years, peaking in 2020–2024. Havre-aux-Maisons is among the rate centres where demand for numbers is still rising quickly.

Dialling a Havre-aux-Maisons number

What a Havre-aux-Maisons number tells you

A number attached to Havre-aux-Maisons tells you that its prefix was issued to a carrier for this rate centre in Quebec, most often Bell Canada. 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 Havre-aux-Maisons: code 367-241 is recorded for Bell Canada, so every 367-241-XXXX number (10,000 possible) descends from that assignment. “Havre-aux-Maisons, Quebec” there names a rate centre, not a municipality, and several area codes overlay it.
