Radisson’s share of its area codes

Within area code 639, Radisson accounts for only 4 of 776 prefixes (0.5%): the code is dominated by Regina and spread over 202 rate centres. Within area code 819, Radisson accounts for only 3 of 770 prefixes (0.4%): the code is dominated by Ottawa-Hull and spread over 211 rate centres. Within area code 474, Radisson accounts for only 2 of 88 prefixes (2.3%): the code is dominated by Saskatoon and spread over 70 rate centres. Within area code 306, Radisson accounts for only 1 of 777 prefixes (0.1%): the code is dominated by Saskatoon and spread over 228 rate centres. Within area code 873, Radisson accounts for only 1 of 667 prefixes (0.1%): the code is dominated by Sherbrooke and spread over 162 rate centres.

Who holds these numbers

Distributel holds the largest share at 3 prefixes, 27.3% of the total, ahead of 6 other carriers. Code by code: in 639, Distributel leads with 2 of 4 prefixes ahead of 2 others; Telebec Ltee. is the only holder in 819; in 474, Fibernetics Corporation leads with 1 of 2 prefixes ahead of 1 others; SaskTel is the only holder in 306; Distributel is the only holder in 873. No carrier holds prefixes in every one of Radisson’s 5 area codes, while 6 appear in just one.

Wireless and wireline

2 of Radisson’s 11 prefixes (18.2%) are held by carriers whose registered name marks a wireless business: Bell Mobility and SaskTel Mobility. Wireline prefixes still outnumber them, carried by Distributel, Telebec Ltee, 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

Radisson’s dated assignments run from 2015 to 2022. The busiest period was 2015–2019, when 5 prefixes went to 3 carriers. 4 prefixes (36%) 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.

Radisson’s oldest prefixes, the ones the register leaves undated, belong to Telebec Ltee and SaskTel: these carriers made up the landscape before competition arrived. The first dated assignment went to SaskTel Mobility in 2015. The most recent arrivals are Fibernetics Corporation (2022), ISP Telecom Inc. (2022) and Distributel (2016), a sign that new carriers are still asking for numbers in Radisson.

Radisson has only 11 prefixes, or 110,000 numbers: a small rate centre, where the arrival of a single new carrier visibly changes the landscape.

No single carrier dominates Radisson: the leader, Distributel, holds only 27.3% 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: 28.6% 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.

The register also shows 1 prefix assigned but not yet in service in Radisson (Access Communications Co-operative Limited): numbers that will start showing up on call displays in the coming months.

Dialling a Radisson number

Radisson is served by 5 overlaid area codes (639, 819, 474, 306 and 873). A 873 number is no more “out of town” than a 639 one; from abroad, dial +1 and the full ten digits.

The numbering neighbourhood

Radisson shares area codes 639, 819, 474, 306 and 873 with at least 20 other rate centres, including Regina, Saskatoon, Ottawa-Hull, Sherbrooke, Trois-Rivieres, Moose Jaw, Drummondville and Prince Albert. The largest of them, Regina, holds 161 prefixes in 306, 474 and 639; the smallest on the list, Swift Current, has just 18.

What a Radisson number tells you

A number attached to Radisson 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 Radisson: code 639-374 is recorded for Distributel, so every 639-374-XXXX number (10,000 possible) descends from that assignment. “Radisson, Saskatchewan” there names a rate centre, not a municipality, and several area codes overlay it.
