Leask’s share of its area codes

Within area code 306, Leask accounts for only 2 of 777 prefixes (0.3%): the code is dominated by Saskatoon and spread over 228 rate centres. Within area code 639, Leask accounts for only 2 of 776 prefixes (0.3%): the code is dominated by Regina and spread over 202 rate centres.

Who holds these numbers

SaskTel holds the largest share at 2 prefixes, 50.0% of the total, ahead of 2 other carriers. Code by code: SaskTel is the only holder in 306; in 639, Bell Mobility leads with 1 of 2 prefixes ahead of 1 others. No carrier holds prefixes in every one of Leask’s 2 area codes, while 3 appear in just one.

Wireless and wireline

2 of Leask’s 4 prefixes (50.0%) are held by carriers whose registered name marks a wireless business: Bell Mobility and SaskTel Mobility. Wireline prefixes still outnumber them, carried by SaskTel. 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

Leask’s dated assignments run from 2016 to 2017. The busiest period was 2015–2019, when 2 prefixes went to 2 carriers. 2 prefixes (50%) 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 Leask is flat.

Leask’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 Bell Mobility in 2016. The most recent arrivals are SaskTel Mobility (2017) and Bell Mobility (2016), a sign that new carriers are still asking for numbers in Leask.

Leask 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.

SaskTel leads with 50.0% of the prefixes, but 2 competitors have set up in Leask: 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 2 prefixes go back to the undated monopoly era. New Leask numbers mostly come out of blocks that were assigned long ago.

Dialling a Leask number

Leask is served by 2 overlaid area codes (306 and 639). A 639 number is no more “out of town” than a 306 one; from abroad, dial +1 and the full ten digits.

The numbering neighbourhood

Leask shares area codes 306 and 639 with at least 20 other rate centres, including Regina, Saskatoon, Moose Jaw, Prince Albert, North Battleford, Yorkton, Swift Current and Moosomin. The largest of them, Regina, holds 157 prefixes in 306 and 639; the smallest on the list, Rosthern, has just 12.

What a Leask number tells you

A number attached to Leask tells you that its prefix was issued to a carrier for this rate centre in Saskatchewan, most often SaskTel. 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 a Saskatchewan area code is easy to borrow to look local.

Reading a register entry for Leask: code 306-226 is recorded for SaskTel, so every 306-226-XXXX number (10,000 possible) descends from that assignment. “Leask, Saskatchewan” there names a rate centre, not a municipality, and several area codes overlay it.
