Who holds these numbers

Bell West Inc. holds the largest share at 1 prefixes, 25.0% of the total, ahead of 3 other carriers. Code by code: in 204, MTS Inc. leads with 1 of 2 prefixes ahead of 1 others; in 431, Bell West Inc. leads with 1 of 2 prefixes ahead of 1 others. No carrier holds prefixes in every one of Stony Mountain’s 2 area codes, while 4 appear in just one.

Wireless and wireline

None of Stony Mountain’s holders carries a mobility brand in its registered name: all 4 prefixes belong to wireline or wholesale carriers, among them Bell West Inc, LES.NET (1996) Inc, MTS Inc and TELUS Integrated Communications. A call showing a Stony Mountain number therefore nominally comes from a landline, cable or VoIP platform rather than a locally assigned cellphone.

How the allocation was built up

Stony Mountain’s dated assignments run from 2013 to 2020. The busiest period was 2010–2014, 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. Since 2020 another 1 prefixes have been added, so the rate centre is still growing.

Stony Mountain’s oldest prefixes, the ones the register leaves undated, belong to MTS Inc: this carrier made up the landscape before competition arrived. The first dated assignment went to TELUS Integrated Communications in 2013. The most recent arrivals are LES.NET (1996) Inc. (2020), Bell West Inc. (2019) and TELUS Integrated Communications (2013), a sign that new carriers are still asking for numbers in Stony Mountain.

Stony Mountain 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.

No single carrier dominates Stony Mountain: the leader, Bell West Inc., holds only 25.0% of the prefixes against 3 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: 33.3% of the dated prefixes go back to the last ten years, the most active period being 2010–2014. The rate centre is growing at a regular rather than explosive pace.

What a Stony Mountain number tells you

A number attached to Stony Mountain tells you that its prefix was issued to a carrier for this rate centre in Manitoba, most often Bell West Inc.. It does not tell you where the handset is today: a subscriber may have ported the number to any of the 4 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 Manitoba area code is easy to borrow to look local.

An allocation says who was issued the prefix, not who serves the number today: numbers can be ported between carriers, and caller ID can be spoofed outright.
