Mont-Joli’s share of its area codes

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

Who holds these numbers

TELUS Quebec holds the largest share at 3 prefixes, 50.0% of the total, ahead of 2 other carriers. Code by code: in 367, TELUS Quebec leads with 1 of 2 prefixes ahead of 1 others; TELUS Quebec is the only holder in 418; in 581, Iristel Inc. leads with 1 of 2 prefixes ahead of 1 others. No carrier holds prefixes in every one of Mont-Joli’s 3 area codes, while 1 appears in just one.

Wireless and wireline

None of Mont-Joli’s holders carries a mobility brand in its registered name: all 6 prefixes belong to wireline or wholesale carriers, among them TELUS Quebec, Iristel Inc and Bell Canada. A call showing a Mont-Joli number therefore nominally comes from a landline, cable or VoIP platform rather than a locally assigned cellphone.

How the allocation was built up

Mont-Joli’s dated assignments run from 2002 to 2024. The busiest period was 2015–2019, when 2 prefixes went to 2 carriers. 1 prefixes (17%) 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.

Mont-Joli’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 2002. The most recent arrivals are Iristel Inc. (2018), Bell Canada (2018) and TELUS Quebec (2002), a sign that new carriers are still asking for numbers in Mont-Joli.

Mont-Joli has just 6 prefixes (60,000 numbers): a very small rate centre, typical of a village or rural area served by a single switching office.

TELUS Quebec leads with 50.0% of the prefixes, but 2 competitors have set up in Mont-Joli: a market where the incumbent keeps the edge without exclusivity.

Demand remains steady: 40.0% of the dated prefixes go back to the last ten years, the most active period being 2015–2019. The rate centre is growing at a regular rather than explosive pace.

Dialling a Mont-Joli number

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

The numbering neighbourhood

Mont-Joli shares area codes 367, 418 and 581 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 Mont-Joli number tells you

A number attached to Mont-Joli 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 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 Mont-Joli: code 367-444 is recorded for TELUS Quebec, so every 367-444-XXXX number (10,000 possible) descends from that assignment. “Mont-Joli, Quebec” there names a rate centre, not a municipality, and several area codes overlay it.
