Saint-Basile’s share of its area codes

Within area code 418, Saint-Basile accounts for only 2 of 777 prefixes (0.3%): the code is dominated by Quebec and spread over 258 rate centres. Within area code 506, Saint-Basile accounts for only 2 of 677 prefixes (0.3%): the code is dominated by Moncton and spread over 88 rate centres. Within area code 581, Saint-Basile 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

Videotron Ltd. holds the largest share at 2 prefixes, 33.3% of the total, ahead of 4 other carriers. Code by code: in 418, Videotron Ltd. leads with 1 of 2 prefixes ahead of 1 others; in 506, Aliant Telecom(NB) leads with 1 of 2 prefixes ahead of 1 others; in 581, Videotron Ltd. leads with 1 of 2 prefixes ahead of 1 others. No carrier holds prefixes in every one of Saint-Basile’s 3 area codes, while 4 appear in just one.

Wireless and wireline

None of Saint-Basile’s holders carries a mobility brand in its registered name: all 6 prefixes belong to wireline or wholesale carriers, among them Videotron Ltd, Aliant Telecom(NB), Bell Canada and Rogers Communications Canada Inc. (Cable). A call showing a Saint-Basile number therefore nominally comes from a landline, cable or VoIP platform rather than a locally assigned cellphone.

How the allocation was built up

Saint-Basile’s dated assignments run from 2007 to 2018. The busiest period was 2005–2009, when 2 prefixes went to 2 carriers. 2 prefixes (33%) 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 Saint-Basile is flat.

Saint-Basile’s oldest prefixes, the ones the register leaves undated, belong to Aliant Telecom(NB) and TELUS Quebec: these carriers made up the landscape before competition arrived. The first dated assignment went to Rogers Communications Canada Inc. (Cable) in 2007. The most recent arrivals are Bell Canada (2018), Videotron Ltd. (2007) and Rogers Communications Canada Inc. (Cable) (2007), a sign that new carriers are still asking for numbers in Saint-Basile.

Saint-Basile 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.

No single carrier dominates Saint-Basile: the leader, Videotron Ltd., holds only 33.3% of the prefixes against 4 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 0.0% of the dated prefixes are less than ten years old, most having been handed out in 2005–2009, and 2 prefixes go back to the undated monopoly era. New Saint-Basile numbers mostly come out of blocks that were assigned long ago.

Dialling a Saint-Basile number

Saint-Basile is served by 3 overlaid area codes (418, 506 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

Saint-Basile shares area codes 418, 506 and 581 with at least 20 other rate centres, including Quebec, Moncton, Saint John, Fredericton, Chicoutimi, Alma, Rimouski and Miramichi. The largest of them, Quebec, holds 245 prefixes in 418 and 581; the smallest on the list, Campbellton, has just 16.

What a Saint-Basile number tells you

A number attached to Saint-Basile 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 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 Saint-Basile: code 418-500 is recorded for Videotron Ltd., so every 418-500-XXXX number (10,000 possible) descends from that assignment. “Saint-Basile, Quebec” there names a rate centre, not a municipality, and several area codes overlay it.
