Nominingue’s share of its area codes

Within area code 873, Nominingue accounts for only 3 of 667 prefixes (0.4%): the code is dominated by Sherbrooke and spread over 162 rate centres. Within area code 819, Nominingue accounts for only 2 of 770 prefixes (0.3%): the code is dominated by Ottawa-Hull and spread over 211 rate centres. Within area code 468, Nominingue accounts for only 1 of 67 prefixes (1.5%): the code is dominated by Ottawa-Hull and spread over 57 rate centres.

Who holds these numbers

ISP Telecom Inc. holds the largest share at 2 prefixes, 33.3% of the total, ahead of 4 other carriers. Code by code: in 873, ISP Telecom Inc. leads with 1 of 3 prefixes ahead of 2 others; in 819, Bell Canada leads with 1 of 2 prefixes ahead of 1 others; ISP Telecom Inc. is the only holder in 468. No carrier holds prefixes in every one of Nominingue’s 3 area codes, while 4 appear in just one.

Wireless and wireline

1 of Nominingue’s 6 prefixes (16.7%) are held by carriers whose registered name marks a wireless business: Bell Mobility. Wireline prefixes still outnumber them, carried by ISP Telecom Inc, Bell Canada, TELUS Quebec and Videotron Ltd. This is a sort by name, not a licence lookup, and a mobile prefix may have been ported to another network since.

How the allocation was built up

Nominingue’s dated assignments run from 2006 to 2026. The busiest period was 2005–2009, when 1 prefixes went to 1 carrier. 1 prefixes (17%) carry no date in the register: these are the historic pre-1999 assignments, the wireline bedrock of the rate centre. Since 2020 another 2 prefixes have been added, so the rate centre is still growing.

Nominingue’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 Bell Mobility in 2006. The most recent arrivals are TELUS Quebec (2026), Videotron Ltd. (2017) and ISP Telecom Inc. (2012), a sign that new carriers are still asking for numbers in Nominingue.

Nominingue 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 Nominingue: the leader, ISP Telecom Inc., 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.

Demand remains steady: 40.0% of the dated prefixes go back to the last ten years, the most active period being 2005–2009. The rate centre is growing at a regular rather than explosive pace.

Dialling a Nominingue number

Nominingue is served by 3 overlaid area codes (873, 819 and 468). A 468 number is no more “out of town” than a 873 one; from abroad, dial +1 and the full ten digits.

The numbering neighbourhood

Nominingue shares area codes 873, 819 and 468 with at least 20 other rate centres, including Ottawa-Hull, Sherbrooke, Trois-Rivieres, Drummondville, Victoriaville, Gatineau, Val-D'Or and Maniwaki. The largest of them, Ottawa-Hull, holds 122 prefixes in 468, 819 and 873; the smallest on the list, Ville-Marie, has just 12.

What a Nominingue number tells you

A number attached to Nominingue tells you that its prefix was issued to a carrier for this rate centre in Quebec, most often ISP Telecom Inc.. 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 Nominingue: code 873-282 is recorded for ISP Telecom Inc., so every 873-282-XXXX number (10,000 possible) descends from that assignment. “Nominingue, Quebec” there names a rate centre, not a municipality, and several area codes overlay it.
