Who holds these numbers

Distributel holds the largest share at 2 prefixes, 15.4% of the total, ahead of 9 other carriers. Code by code: in 639, Distributel leads with 2 of 5 prefixes ahead of 3 others; in 418, TELUS Quebec leads with 1 of 3 prefixes ahead of 2 others; in 581, TELUS Quebec leads with 1 of 2 prefixes ahead of 1 others; SaskTel is the only holder in 306; ISP Telecom Inc. is the only holder in 367; Fibernetics Corporation is the only holder in 474. No carrier holds prefixes in every one of Delisle’s 6 area codes, while 8 appear in just one.

Wireless and wireline

1 of Delisle’s 13 prefixes (7.7%) are held by carriers whose registered name marks a wireless business: Bell Mobility. Wireline prefixes still outnumber them, carried by Distributel, ISP Telecom Inc, TELUS Quebec and Access Communications Co-operative Limited. 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

Delisle’s dated assignments run from 2007 to 2023. The busiest period was 2015–2019, when 5 prefixes went to 4 carriers. 2 prefixes (15%) 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.

Delisle’s oldest prefixes, the ones the register leaves undated, belong to Bell Canada and SaskTel: these carriers made up the landscape before competition arrived. The first dated assignment went to Videotron Ltd. in 2007. The most recent arrivals are Fibernetics Corporation (2022), ISP Telecom Inc. (2022) and Access Communications Co-operative Limited (2018), a sign that new carriers are still asking for numbers in Delisle.

Delisle has only 13 prefixes, or 130,000 numbers: a small rate centre, where the arrival of a single new carrier visibly changes the landscape.

No single carrier dominates Delisle: the leader, Distributel, holds only 15.4% 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.

Demand remains steady: 27.3% 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.

Dialling a Delisle number

Delisle is served by 6 overlaid area codes (639, 418, 581, 306, 367 and 474). A 474 number is no more “out of town” than a 639 one; from abroad, dial +1 and the full ten digits.

The numbering neighbourhood

Delisle shares area codes 639, 418, 581, 306, 367 and 474 with at least 20 other rate centres, including Quebec, Regina, Saskatoon, Chicoutimi, Moose Jaw, Alma, Rimouski and Riviere-du-Loup. The largest of them, Quebec, holds 282 prefixes in 367, 418 and 581; the smallest on the list, Yorkton, has just 19.

What a Delisle number tells you

A number attached to Delisle 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 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 a Saskatchewan area code is easy to borrow to look local.

Reading a register entry for Delisle: code 639-349 is recorded for Distributel, so every 639-349-XXXX number (10,000 possible) descends from that assignment. “Delisle, Saskatchewan” there names a rate centre, not a municipality, and several area codes overlay it.
