|---|---|---|---|---|
| Iristel Inc. | 2 | 1 | — | 3 |
| Bell West Inc. | 1 | — | — | 1 |

Wireless and wireline
None of Langdon’s holders carries a mobility brand in its registered name: all 10 prefixes belong to wireline or wholesale carriers, among them Iristel Inc, Bell West Inc, Bragg Communications Inc and Distributel. A call showing a Langdon number therefore nominally comes from a landline, cable or VoIP platform rather than a locally assigned cellphone.
How the allocation was built up
Langdon’s dated assignments run from 2009 to 2022. The busiest period was 2015–2019, when 5 prefixes went to 4 carriers. 1 prefixes (10%) carry no date in the register: these are the historic pre-1999 assignments, the wireline bedrock of the rate centre. Since 2020 another 3 prefixes have been added, so the rate centre is still growing.
Langdon’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 Bragg Communications Inc. in 2009. The most recent arrivals are ISP Telecom Inc. (2021), Fibernetics Corporation (2020) and IXICA Communications Inc. (2018), a sign that new carriers are still asking for numbers in Langdon.
Langdon has only 10 prefixes, or 100,000 numbers: a small rate centre, where the arrival of a single new carrier visibly changes the landscape.
No single carrier dominates Langdon: the leader, Iristel Inc., holds only 30.0% of the prefixes against 7 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 2015–2019. The rate centre is growing at a regular rather than explosive pace.
| Period | Prefixes | Carriers |
|---|---|---|
| 2005–2009 | 1 | 1 |
| 2015–2019 | 5 | 4 |
| 2020–2024 | 3 | 3 |

What a Langdon number tells you
A number attached to Langdon tells you that its prefix was issued to a carrier for this rate centre in Alberta, most often Iristel Inc.. It does not tell you where the handset is today: a subscriber may have ported the number to any of the 8 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 Langdon: code 587-871 is recorded for Iristel Inc., so every 587-871-XXXX number (10,000 possible) descends from that assignment. “Langdon, 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.
