Porcupine Plain’s share of its area codes

Within area code 306, Porcupine Plain accounts for only 3 of 777 prefixes (0.4%): the code is dominated by Saskatoon and spread over 228 rate centres. Within area code 639, Porcupine Plain 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

Access Communications Co-operative Limited holds the largest share at 1 prefixes, 20.0% of the total, ahead of 4 other carriers. Code by code: in 306, SaskTel leads with 1 of 3 prefixes ahead of 2 others; in 639, Access Communications Co-operative Limited leads with 1 of 2 prefixes ahead of 1 others. No carrier holds prefixes in every one of Porcupine Plain’s 2 area codes, while 5 appear in just one.

Wireless and wireline

3 of Porcupine Plain’s 5 prefixes (60.0%) are held by carriers whose registered name marks a wireless business: Bell Mobility, SaskTel Mobility and TELUS Mobility. That makes this a mostly mobile rate centre, which is typical of recent allocations: new prefixes go overwhelmingly to cellphones. 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

Porcupine Plain’s dated assignments run from 2010 to 2025. The busiest period was 2010–2014, when 2 prefixes went to 2 carriers. 1 prefixes (20%) carry no date in the register: these are the historic pre-1999 assignments, the wireline bedrock of the rate centre. Since 2020 another 1 prefixes have been added, so the rate centre is still growing.

Porcupine Plain’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 TELUS Mobility in 2010. The most recent arrivals are Access Communications Co-operative Limited (2025), Bell Mobility (2016) and SaskTel Mobility (2010), a sign that new carriers are still asking for numbers in Porcupine Plain.

Porcupine Plain has just 5 prefixes (50,000 numbers): a very small rate centre, typical of a village or rural area served by a single switching office.

No single carrier dominates Porcupine Plain: the leader, Access Communications Co-operative Limited, holds only 20.0% of the prefixes against 4 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: 25.0% of the dated prefixes go back to the last ten years, the most active period being 2010–2014. The rate centre is growing at a regular rather than explosive pace.

Dialling a Porcupine Plain number

Porcupine Plain 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

Porcupine Plain 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 Porcupine Plain number tells you

A number attached to Porcupine Plain 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: most of Porcupine Plain’s prefixes are mobile, and a cellphone keeps its number when its owner moves across the country. 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 Porcupine Plain: code 639-572 is recorded for Access Communications Co-operative Limited, so every 639-572-XXXX number (10,000 possible) descends from that assignment. “Porcupine Plain, Saskatchewan” there names a rate centre, not a municipality, and several area codes overlay it.
