Vallee-Jonction’s share of its area codes

Within area code 581, Vallee-Jonction accounts for only 4 of 778 prefixes (0.5%): the code is dominated by Quebec and spread over 232 rate centres. Within area code 418, Vallee-Jonction accounts for only 1 of 777 prefixes (0.1%): the code is dominated by Quebec and spread over 258 rate centres.

Who holds these numbers

Videotron Ltd. holds the largest share at 2 prefixes, 40.0% of the total, ahead of 3 other carriers. Code by code: in 581, Videotron Ltd. leads with 2 of 4 prefixes ahead of 2 others; TELUS Quebec is the only holder in 418. No carrier holds prefixes in every one of Vallee-Jonction’s 2 area codes, while 4 appear in just one.

Wireless and wireline

None of Vallee-Jonction’s holders carries a mobility brand in its registered name: all 5 prefixes belong to wireline or wholesale carriers, among them Videotron Ltd, Bell Canada, TELUS Quebec and Telecommunications Xittel Inc. A call showing a Vallee-Jonction number therefore nominally comes from a landline, cable or VoIP platform rather than a locally assigned cellphone.

How the allocation was built up

Vallee-Jonction’s dated assignments run from 2009 to 2018. The busiest period was 2015–2019, when 2 prefixes went to 2 carriers. 1 prefixes (20%) carry no date in the register: these are the historic pre-1999 assignments, the wireline bedrock of the rate centre. No prefix has been added since 2020: demand for numbers in Vallee-Jonction is flat.

Vallee-Jonction’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 Videotron Ltd. in 2009. The most recent arrivals are Bell Canada (2018), Telecommunications Xittel Inc (2012) and Videotron Ltd. (2009), a sign that new carriers are still asking for numbers in Vallee-Jonction.

Vallee-Jonction has just 5 prefixes (50,000 numbers): a very small rate centre, typical of a village or rural area served by a single switching office.

Videotron Ltd. leads with 40.0% of the prefixes, but 3 competitors have set up in Vallee-Jonction: a market where the incumbent keeps the edge without exclusivity.

Allocation is mature: only 0.0% of the dated prefixes are less than ten years old, most having been handed out in 2015–2019, and 1 prefixes go back to the undated monopoly era. New Vallee-Jonction numbers mostly come out of blocks that were assigned long ago.

1 undated in the register.

Dialling a Vallee-Jonction number

Vallee-Jonction is served by 2 overlaid area codes (581 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

Vallee-Jonction shares area codes 581 and 418 with at least 20 other rate centres, including Quebec, Chicoutimi, Rimouski, Alma, Riviere-du-Loup, Thetford Mines, Levis and Saint-Georges-de-Beauce. The largest of them, Quebec, holds 245 prefixes in 418 and 581; the smallest on the list, Chibougamau, has just 11.

What a Vallee-Jonction number tells you

A number attached to Vallee-Jonction 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 4 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 Vallee-Jonction: code 581-225 is recorded for Videotron Ltd., so every 581-225-XXXX number (10,000 possible) descends from that assignment. “Vallee-Jonction, Quebec” there names a rate centre, not a municipality, and several area codes overlay it.
