Ste-Sabine’s share of its area codes

Within area code 450, Ste-Sabine accounts for only 1 of 775 prefixes (0.1%): the code is dominated by Granby and spread over 129 rate centres. Within area code 579, Ste-Sabine accounts for only 1 of 644 prefixes (0.2%): the code is dominated by Granby and spread over 126 rate centres.

Who holds these numbers

Telebec Ltee. holds the largest share at 1 prefixes, 50.0% of the total, ahead of 1 other carrier. Code by code: Telebec Ltee. is the only holder in 450; Videotron Ltd. is the only holder in 579. No carrier holds prefixes in every one of Ste-Sabine’s 2 area codes, while 2 appear in just one.

Wireless and wireline

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

How the allocation was built up

Ste-Sabine’s dated assignments run from 2010 to 2010. The busiest period was 2010–2014, when 2 prefixes went to 2 carriers. Every assignment is dated, the sign of a rate centre built entirely within the period CNAC has kept dated records. No prefix has been added since 2020: demand for numbers in Ste-Sabine is flat.

None of Ste-Sabine’s prefixes predates the dated records: the rate centre was built entirely in the competitive era. The first dated assignment went to Telebec Ltee. in 2010. The most recent arrivals are Videotron Ltd. (2010) and Telebec Ltee. (2010), a sign that new carriers are still asking for numbers in Ste-Sabine.

Ste-Sabine 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.

Telebec Ltee. leads with 50.0% of the prefixes, but 1 competitors have set up in Ste-Sabine: 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 2010–2014. New Ste-Sabine numbers mostly come out of blocks that were assigned long ago.

Dialling a Ste-Sabine number

Ste-Sabine is served by 2 overlaid area codes (450 and 579). A 579 number is no more “out of town” than a 450 one; from abroad, dial +1 and the full ten digits.

The numbering neighbourhood

Ste-Sabine shares area codes 450 and 579 with at least 20 other rate centres, including Granby, Joliette, St-Jerome, St-Hyacinthe, Longueuil, Ste-Therese, Pont-Viau and Sorel. The largest of them, Granby, holds 51 prefixes in 450 and 579; the smallest on the list, Lachute, has just 17.

What a Ste-Sabine number tells you

A number attached to Ste-Sabine tells you that its prefix was issued to a carrier for this rate centre in Quebec, most often Telebec Ltee.. It does not tell you where the handset is today: a subscriber may have ported the number to any of the 2 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 Ste-Sabine: code 450-393 is recorded for Telebec Ltee., so every 450-393-XXXX number (10,000 possible) descends from that assignment. “Ste-Sabine, Quebec” there names a rate centre, not a municipality, and several area codes overlay it.
