Jonquiere’s share of its area codes

Within area code 418, Jonquiere accounts for only 10 of 777 prefixes (1.3%): the code is dominated by Quebec and spread over 258 rate centres. Within area code 581, Jonquiere accounts for only 6 of 778 prefixes (0.8%): the code is dominated by Quebec and spread over 232 rate centres. Within area code 367, Jonquiere accounts for only 1 of 233 prefixes (0.4%): the code is dominated by Quebec and spread over 111 rate centres.

Who holds these numbers

Bell Canada holds the largest share at 6 prefixes, 35.3% of the total, ahead of 7 other carriers. Code by code: in 418, Bell Canada leads with 6 of 10 prefixes ahead of 2 others; in 581, TELUS Quebec leads with 2 of 6 prefixes ahead of 4 others; ISP Telecom Inc. is the only holder in 367. No carrier holds prefixes in every one of Jonquiere’s 3 area codes, while 7 appear in just one.

Wireless and wireline

None of Jonquiere’s holders carries a mobility brand in its registered name: all 17 prefixes belong to wireline or wholesale carriers, among them Bell Canada, TELUS Quebec, Videotron Ltd and Bell Aliant, a division of Bell Canada. A call showing a Jonquiere number therefore nominally comes from a landline, cable or VoIP platform rather than a locally assigned cellphone.

How the allocation was built up

Jonquiere’s dated assignments run from 2005 to 2023. The busiest period was 2005–2009, when 4 prefixes went to 2 carriers. 6 prefixes (35%) carry no date in the register: these are the historic pre-1999 assignments, the wireline bedrock of the rate centre. Since 2020 another 1 prefixes have been added, so the rate centre is still growing.

Jonquiere’s oldest prefixes, the ones the register leaves undated, belong to Bell Canada: this carrier made up the landscape before competition arrived. The first dated assignment went to Videotron Ltd. in 2005. The most recent arrivals are ISP Telecom Inc. (2023), Distributel (2018) and Bell Aliant, a division of Bell Canada (2014), a sign that new carriers are still asking for numbers in Jonquiere.

Jonquiere has only 17 prefixes, or 170,000 numbers: a small rate centre, where the arrival of a single new carrier visibly changes the landscape.

No single carrier dominates Jonquiere: the leader, Bell Canada, holds only 35.3% of the prefixes against 7 competitors, a sign of a highly fragmented market where cable companies, mobility brands and VoIP providers weigh as much as the incumbent.

Allocation is mature: only 9.1% of the dated prefixes are less than ten years old, most having been handed out in 2005–2009, and 6 prefixes go back to the undated monopoly era. New Jonquiere numbers mostly come out of blocks that were assigned long ago.

Dialling a Jonquiere number

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

The numbering neighbourhood

Jonquiere shares area codes 418, 581 and 367 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, Chandler, has just 13.

What a Jonquiere number tells you

A number attached to Jonquiere 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 8 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 Jonquiere: code 418-542 is recorded for Bell Canada, so every 418-542-XXXX number (10,000 possible) descends from that assignment. “Jonquiere, Quebec” there names a rate centre, not a municipality, and several area codes overlay it.
