Wireless and wireline
None of Ardrossan’s holders carries a mobility brand in its registered name: all 4 prefixes belong to wireline or wholesale carriers, among them TELUS, Distributel and Shaw Telecom Inc. A call showing a Ardrossan number therefore nominally comes from a landline, cable or VoIP platform rather than a locally assigned cellphone.
How the allocation was built up
Ardrossan’s dated assignments run from 2009 to 2017. The busiest period was 2015–2019, when 2 prefixes went to 2 carriers. 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 Ardrossan is flat.
Ardrossan’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 Shaw Telecom Inc. in 2009. The most recent arrivals are TELUS (2017), Distributel (2016) and Shaw Telecom Inc. (2009), a sign that new carriers are still asking for numbers in Ardrossan.
Ardrossan 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 leads with 50.0% of the prefixes, but 2 competitors have set up in Ardrossan: 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 2015–2019, and 1 prefixes go back to the undated monopoly era. New Ardrossan numbers mostly come out of blocks that were assigned long ago.
| Period | Prefixes | Carriers |
|---|---|---|
| 2005–2009 | 1 | 1 |
| 2015–2019 | 2 | 2 |

What a Ardrossan number tells you
A number attached to Ardrossan 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 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 an Alberta area code is easy to borrow to look local.
Reading a register entry for Ardrossan: code 780-922 is recorded for TELUS, so every 780-922-XXXX number (10,000 possible) descends from that assignment. “Ardrossan, 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.
