Barachois’s share of its area codes

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

Who holds these numbers

TELUS Quebec holds every prefix here. Code by code: TELUS Quebec is the only holder in 418; TELUS Quebec is the only holder in 581. 1 carrier holds prefixes in every one of Barachois’s 2 area codes, while all of them hold prefixes in more than one.

Wireless and wireline

None of Barachois’s holders carries a mobility brand in its registered name: all 2 prefixes belong to wireline or wholesale carriers, among them TELUS Quebec. A call showing a Barachois number therefore nominally comes from a landline, cable or VoIP platform rather than a locally assigned cellphone.

How the allocation was built up

Barachois’s dated assignments run from 2011 to 2011. The busiest period was 2010–2014, when 1 prefixes went to 1 carrier. 1 prefixes (50%) 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 Barachois is flat.

TELUS Quebec is the only carrier ever recorded for Barachois: no competitor has obtained a prefix here, and the latest assignment dates from 2011. A single-carrier rate centre is typical of small communities where only the incumbent ever built a network.

Barachois has just 2 prefixes (20,000 numbers): a very small rate centre, typical of a village or rural area served by a single switching office.

The local market is an allocation monopoly: TELUS Quebec holds every prefix, and no competitor has ever requested a code for Barachois.

Allocation is mature: only 0.0% of the dated prefixes are less than ten years old, most having been handed out in 2010–2014, and 1 prefixes go back to the undated monopoly era. New Barachois numbers mostly come out of blocks that were assigned long ago.

Dialling a Barachois number

Barachois is served by 2 overlaid area codes (418 and 581). A 581 number is no more “out of town” than a 418 one; from abroad, dial +1 and the full ten digits.

The numbering neighbourhood

Barachois shares area codes 418 and 581 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 Barachois number tells you

A number attached to Barachois 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 1 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 Barachois: code 418-645 is recorded for TELUS Quebec, so every 418-645-XXXX number (10,000 possible) descends from that assignment. “Barachois, Quebec” there names a rate centre, not a municipality, and several area codes overlay it.
