Wireless and wireline
5 of Rocky Mountain House’s 16 prefixes (31.3%) are held by carriers whose registered name marks a wireless business: TELUS Mobility, Bell Mobility, Fido Solutions Inc and Rogers Communications Canada Inc. (Wireless). Wireline prefixes still outnumber them, carried by TELUS, Distributel, Iristel Inc and Bell West Inc. 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
Rocky Mountain House’s dated assignments run from 2000 to 2022. The busiest period was 2000–2004, when 4 prefixes went to 3 carriers. 2 prefixes (13%) 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.
Rocky Mountain House’s oldest prefixes, the ones the register leaves undated, belong to TELUS: this carrier made up the landscape before competition arrived. The first dated assignment went to TELUS Mobility in 2000. The most recent arrivals are ISP Telecom Inc. (2022), Bell West Inc. (2019) and Iristel Inc. (2016), a sign that new carriers are still asking for numbers in Rocky Mountain House.
Rocky Mountain House has only 16 prefixes, or 160,000 numbers: a small rate centre, where the arrival of a single new carrier visibly changes the landscape.
No single carrier dominates Rocky Mountain House: the leader, TELUS, holds only 25.0% of the prefixes against 9 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 14.3% of the dated prefixes are less than ten years old, most having been handed out in 2000–2004, and 2 prefixes go back to the undated monopoly era. New Rocky Mountain House numbers mostly come out of blocks that were assigned long ago.
| Period | Prefixes | Carriers |
|---|---|---|
| 2000–2004 | 4 | 3 |
| 2005–2009 | 2 | 2 |
| 2010–2014 | 3 | 3 |
| 2015–2019 | 3 | 3 |

What a Rocky Mountain House number tells you
A number attached to Rocky Mountain House tells you that its prefix was issued to a carrier for this rate centre in Alberta, most often TELUS. It does not tell you where the handset is today: a subscriber may have ported the number to any of the 10 carriers present here or to a VoIP service usable anywhere. Nor does it tell you who is calling: caller ID can be spoofed, and an Alberta area code is easy to borrow to look local.
Reading a register entry for Rocky Mountain House: code 403-844 is recorded for TELUS, so every 403-844-XXXX number (10,000 possible) descends from that assignment. “Rocky Mountain House, Alberta” there names a rate centre, not a municipality, and several area codes overlay it.

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.
