Yellow Grass’s share of its area codes

Within area code 639, Yellow Grass accounts for only 2 of 776 prefixes (0.3%): the code is dominated by Regina and spread over 202 rate centres. Within area code 306, Yellow Grass accounts for only 1 of 777 prefixes (0.1%): the code is dominated by Saskatoon and spread over 228 rate centres.

Who holds these numbers

Access Communications Co-operative Limited holds the largest share at 1 prefixes, 33.3% of the total, ahead of 2 other carriers. Code by code: in 639, Access Communications Co-operative Limited leads with 1 of 2 prefixes ahead of 1 others; SaskTel is the only holder in 306. No carrier holds prefixes in every one of Yellow Grass’s 2 area codes, while 3 appear in just one.

Wireless and wireline

1 of Yellow Grass’s 3 prefixes (33.3%) are held by carriers whose registered name marks a wireless business: SaskTel Mobility. Wireline prefixes still outnumber them, carried by Access Communications Co-operative Limited and 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

Yellow Grass’s dated assignments run from 2016 to 2017. The busiest period was 2015–2019, when 2 prefixes went to 2 carriers. 1 prefixes (33%) 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 Yellow Grass is flat.

Yellow Grass’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 Access Communications Co-operative Limited in 2016. The most recent arrivals are SaskTel Mobility (2017) and Access Communications Co-operative Limited (2016), a sign that new carriers are still asking for numbers in Yellow Grass.

Yellow Grass has just 3 prefixes (30,000 numbers): a very small rate centre, typical of a village or rural area served by a single switching office.

No single carrier dominates Yellow Grass: the leader, Access Communications Co-operative Limited, holds only 33.3% of the prefixes against 2 competitors, a sign of a highly fragmented market where cable companies, mobility brands and VoIP providers weigh as much as the incumbent.

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 Yellow Grass numbers mostly come out of blocks that were assigned long ago.

Dialling a Yellow Grass number

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

The numbering neighbourhood

Yellow Grass shares area codes 639 and 306 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 Yellow Grass number tells you

A number attached to Yellow Grass tells you that its prefix was issued to a carrier for this rate centre in Saskatchewan, most often Access Communications Co-operative Limited. 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 Yellow Grass: code 639-936 is recorded for Access Communications Co-operative Limited, so every 639-936-XXXX number (10,000 possible) descends from that assignment. “Yellow Grass, Saskatchewan” there names a rate centre, not a municipality, and several area codes overlay it.
