St-Gedeon’s share of its area codes

Within area code 581, St-Gedeon accounts for only 3 of 778 prefixes (0.4%): the code is dominated by Quebec and spread over 232 rate centres. Within area code 418, St-Gedeon 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

TELUS Quebec holds the largest share at 2 prefixes, 50.0% of the total, ahead of 2 other carriers. Code by code: in 581, TELUS Quebec leads with 2 of 3 prefixes ahead of 1 others; Bell Canada is the only holder in 418. No carrier holds prefixes in every one of St-Gedeon’s 2 area codes, while 3 appear in just one.

Wireless and wireline

None of St-Gedeon’s holders carries a mobility brand in its registered name: all 4 prefixes belong to wireline or wholesale carriers, among them TELUS Quebec, Bell Canada and Telecommunications Xittel Inc. A call showing a St-Gedeon number therefore nominally comes from a landline, cable or VoIP platform rather than a locally assigned cellphone.

How the allocation was built up

St-Gedeon’s dated assignments run from 2008 to 2018. The busiest period was 2005–2009, when 1 prefixes went to 1 carrier. 1 prefixes (25%) 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 St-Gedeon is flat.

St-Gedeon’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 TELUS Quebec in 2008. The most recent arrivals are Telecommunications Xittel Inc (2012) and TELUS Quebec (2008), a sign that new carriers are still asking for numbers in St-Gedeon.

St-Gedeon has just 4 prefixes (40,000 numbers): a very small rate centre, typical of a village or rural area served by a single switching office.

TELUS Quebec leads with 50.0% of the prefixes, but 2 competitors have set up in St-Gedeon: 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 2005–2009, and 1 prefixes go back to the undated monopoly era. New St-Gedeon numbers mostly come out of blocks that were assigned long ago.

Dialling a St-Gedeon number

St-Gedeon 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

St-Gedeon 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 St-Gedeon number tells you

A number attached to St-Gedeon 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 3 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 St-Gedeon: code 581-626 is recorded for TELUS Quebec, so every 581-626-XXXX number (10,000 possible) descends from that assignment. “St-Gedeon, Quebec” there names a rate centre, not a municipality, and several area codes overlay it.
