Coronation’s share of its area codes

Within area code 403, Coronation accounts for only 3 of 781 prefixes (0.4%): the code is dominated by Calgary and spread over 142 rate centres. Within area code 587, Coronation accounts for only 1 of 779 prefixes (0.1%): the code is dominated by Calgary and spread over 137 rate centres. Within area code 825, Coronation accounts for only 1 of 769 prefixes (0.1%): the code is dominated by Calgary and spread over 301 rate centres.

Who holds these numbers

Bell Mobility holds the largest share at 1 prefixes, 20.0% of the total, ahead of 4 other carriers. Code by code: in 403, Bell Mobility leads with 1 of 3 prefixes ahead of 2 others; TELUS Mobility is the only holder in 587; Distributel is the only holder in 825. No carrier holds prefixes in every one of Coronation’s 3 area codes, while 5 appear in just one.

Wireless and wireline

3 of Coronation’s 5 prefixes (60.0%) are held by carriers whose registered name marks a wireless business: Bell Mobility, Rogers Communications Canada Inc. (Wireless) 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

Coronation’s dated assignments run from 2006 to 2016. The busiest period was 2005–2009, 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. No prefix has been added since 2020: demand for numbers in Coronation is flat.

Coronation’s oldest prefixes, the ones the register leaves undated, belong to TELUS: this carrier made up the landscape before competition arrived. The first dated assignment went to Rogers Communications Canada Inc. (Wireless) in 2006. The most recent arrivals are Distributel (2016), TELUS Mobility (2010) and Bell Mobility (2007), a sign that new carriers are still asking for numbers in Coronation.

Coronation 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 Coronation: the leader, Bell Mobility, 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.

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 1 prefixes go back to the undated monopoly era. New Coronation numbers mostly come out of blocks that were assigned long ago.

Dialling a Coronation number

Coronation is served by 3 overlaid area codes (403, 587 and 825). A 825 number is no more “out of town” than a 403 one; from abroad, dial +1 and the full ten digits.

The numbering neighbourhood

Coronation shares area codes 403, 587 and 825 with at least 20 other rate centres, including Calgary, Edmonton, Red Deer, Lethbridge, Medicine Hat, Fort McMurray, High River and Banff. The largest of them, Calgary, holds 711 prefixes in 403, 587 and 825; the smallest on the list, Stettler, has just 15.

What a Coronation number tells you

A number attached to Coronation tells you that its prefix was issued to a carrier for this rate centre in Alberta, most often Bell Mobility. It does not tell you where the handset is today: most of Coronation’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 an Alberta area code is easy to borrow to look local.

Reading a register entry for Coronation: code 403-413 is recorded for Bell Mobility, so every 403-413-XXXX number (10,000 possible) descends from that assignment. “Coronation, Alberta” there names a rate centre, not a municipality, and several area codes overlay it.
