Esterhazy’s share of its area codes

Within area code 306, Esterhazy accounts for only 10 of 777 prefixes (1.3%): the code is dominated by Saskatoon and spread over 228 rate centres. Within area code 639, Esterhazy accounts for only 1 of 776 prefixes (0.1%): the code is dominated by Regina and spread over 202 rate centres.

Who holds these numbers

SaskTel holds the largest share at 5 prefixes, 45.5% of the total, ahead of 6 other carriers. Code by code: in 306, SaskTel leads with 5 of 10 prefixes ahead of 5 others; Bell Mobility is the only holder in 639. No carrier holds prefixes in every one of Esterhazy’s 2 area codes, while 7 appear in just one.

Wireless and wireline

4 of Esterhazy’s 11 prefixes (36.4%) are held by carriers whose registered name marks a wireless business: Bell Mobility, Rogers Communications Canada Inc. (Wireless), SaskTel Mobility and TELUS Mobility. Wireline prefixes still outnumber them, carried by SaskTel, Access Communications Co-operative Limited and Zayo Canada 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

Esterhazy’s dated assignments run from 2002 to 2017. The busiest period was 2005–2009, when 2 prefixes went to 2 carriers. 5 prefixes (45%) 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 Esterhazy is flat.

Esterhazy’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 Rogers Communications Canada Inc. (Wireless) in 2002. The most recent arrivals are Bell Mobility (2017), Access Communications Co-operative Limited (2014) and TELUS Mobility (2010), a sign that new carriers are still asking for numbers in Esterhazy.

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

SaskTel leads with 45.5% of the prefixes, but 6 competitors have set up in Esterhazy: 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 2005–2009, and 5 prefixes go back to the undated monopoly era. New Esterhazy numbers mostly come out of blocks that were assigned long ago.

Dialling a Esterhazy number

Esterhazy 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

Esterhazy 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 Esterhazy number tells you

A number attached to Esterhazy 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 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 Esterhazy: code 306-534 is recorded for SaskTel, so every 306-534-XXXX number (10,000 possible) descends from that assignment. “Esterhazy, Saskatchewan” there names a rate centre, not a municipality, and several area codes overlay it.
