Bonaventure’s share of its area codes

Within area code 581, Bonaventure accounts for only 7 of 778 prefixes (0.9%): the code is dominated by Quebec and spread over 232 rate centres. Within area code 367, Bonaventure accounts for only 2 of 232 prefixes (0.9%): the code is dominated by Quebec and spread over 110 rate centres. Within area code 418, Bonaventure accounts for only 2 of 777 prefixes (0.3%): the code is dominated by Quebec and spread over 258 rate centres.

Who holds these numbers

TELUS Quebec holds the largest share at 5 prefixes, 45.5% of the total, ahead of 4 other carriers. Code by code: in 581, TELUS Quebec leads with 3 of 7 prefixes ahead of 2 others; in 367, Cogeco Connexion Inc. leads with 1 of 2 prefixes ahead of 1 others; TELUS Quebec is the only holder in 418. No carrier holds prefixes in every one of Bonaventure’s 3 area codes, while 4 appear in just one.

Wireless and wireline

None of Bonaventure’s holders carries a mobility brand in its registered name: all 11 prefixes belong to wireline or wholesale carriers, among them TELUS Quebec, Iristel Inc, Bell Canada and Cogeco Connexion Inc. A call showing a Bonaventure number therefore nominally comes from a landline, cable or VoIP platform rather than a locally assigned cellphone.

How the allocation was built up

Bonaventure’s dated assignments run from 2011 to 2025. The busiest period was 2010–2014, when 3 prefixes went to 1 carrier. 2 prefixes (18%) 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.

Bonaventure’s oldest prefixes, the ones the register leaves undated, belong to TELUS Quebec: this carrier made up the landscape before competition arrived. The first dated assignment went to TELUS Quebec in 2011. The most recent arrivals are Fibernetics Corporation (2025), Cogeco Connexion Inc. (2025) and Iristel Inc. (2018), a sign that new carriers are still asking for numbers in Bonaventure.

Bonaventure has only 11 prefixes, or 110,000 numbers: a small rate centre, where the arrival of a single new carrier visibly changes the landscape.

TELUS Quebec leads with 45.5% of the prefixes, but 4 competitors have set up in Bonaventure: a market where the incumbent keeps the edge without exclusivity.

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.

Dialling a Bonaventure number

Bonaventure is served by 3 overlaid area codes (581, 367 and 418). A 418 number is no more “out of town” than a 581 one; from abroad, dial +1 and the full ten digits.

The numbering neighbourhood

Bonaventure shares area codes 581, 367 and 418 with at least 20 other rate centres, including Quebec, Chicoutimi, Alma, Rimouski, Riviere-du-Loup, Thetford Mines, Sainte-Marie-de-Beauce and Levis. The largest of them, Quebec, holds 282 prefixes in 367, 418 and 581; the smallest on the list, Saint-Henri-de-Levis, has just 16.

What a Bonaventure number tells you

A number attached to Bonaventure 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 5 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 Bonaventure: code 581-364 is recorded for TELUS Quebec, so every 581-364-XXXX number (10,000 possible) descends from that assignment. “Bonaventure, Quebec” there names a rate centre, not a municipality, and several area codes overlay it.

Every Bonaventure prefix

Each row is an in-service central-office code recorded for Bonaventure, with its original holder and year of assignment.
