Who holds these numbers

Distributel holds the largest share at 2 prefixes, 25.0% of the total, ahead of 6 other carriers. Code by code: in 639, Distributel leads with 2 of 6 prefixes ahead of 4 others; SaskTel is the only holder in 306; Fibernetics Corporation is the only holder in 474. No carrier holds prefixes in every one of Colonsay’s 3 area codes, while 7 appear in just one.

Wireless and wireline

2 of Colonsay’s 8 prefixes (25.0%) are held by carriers whose registered name marks a wireless business: Bell Mobility and SaskTel Mobility. Wireline prefixes still outnumber them, carried by Distributel, Access Communications Co-operative Limited, Fibernetics Corporation and ISP Telecom 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

Colonsay’s dated assignments run from 2015 to 2024. The busiest period was 2015–2019, when 4 prefixes went to 3 carriers. 1 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 3 prefixes have been added, so the rate centre is still growing.

Colonsay’s oldest prefixes, the ones the register leaves undated, belong to SaskTel: this carrier made up the landscape before competition arrived. The first dated assignment went to SaskTel Mobility in 2015. The most recent arrivals are Access Communications Co-operative Limited (2024), Fibernetics Corporation (2023) and ISP Telecom Inc. (2022), a sign that new carriers are still asking for numbers in Colonsay.

Colonsay has just 8 prefixes (80,000 numbers): a very small rate centre, typical of a village or rural area served by a single switching office.

No single carrier dominates Colonsay: the leader, Distributel, holds only 25.0% of the prefixes against 6 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: 42.9% 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.

What a Colonsay number tells you

A number attached to Colonsay tells you that its prefix was issued to a carrier for this rate centre in Saskatchewan, most often Distributel. It does not tell you where the handset is today: a subscriber may have ported the number to any of the 7 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 Saskatchewan area code is easy to borrow to look local.

Reading a register entry for Colonsay: code 639-346 is recorded for Distributel, so every 639-346-XXXX number (10,000 possible) descends from that assignment. “Colonsay, Saskatchewan” 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.
