Gleichen’s share of its area codes

Within area code 587, Gleichen accounts for only 3 of 779 prefixes (0.4%): the code is dominated by Calgary and spread over 137 rate centres. Within area code 403, Gleichen accounts for only 1 of 781 prefixes (0.1%): the code is dominated by Calgary and spread over 142 rate centres. Within area code 825, Gleichen 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 West Inc. holds the largest share at 1 prefixes, 20.0% of the total, ahead of 4 other carriers. Code by code: in 587, Bell West Inc. leads with 1 of 3 prefixes ahead of 2 others; TELUS is the only holder in 403; Fibernetics Corporation is the only holder in 825. No carrier holds prefixes in every one of Gleichen’s 3 area codes, while 5 appear in just one.

Wireless and wireline

None of Gleichen’s holders carries a mobility brand in its registered name: all 5 prefixes belong to wireline or wholesale carriers, among them Bell West Inc, Distributel, Fibernetics Corporation and IXICA Communications Inc. A call showing a Gleichen number therefore nominally comes from a landline, cable or VoIP platform rather than a locally assigned cellphone.

How the allocation was built up

Gleichen’s dated assignments run from 2016 to 2023. The busiest period was 2015–2019, when 3 prefixes went to 3 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.

Gleichen’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 Distributel in 2016. The most recent arrivals are Fibernetics Corporation (2023), IXICA Communications Inc. (2018) and Bell West Inc. (2017), a sign that new carriers are still asking for numbers in Gleichen.

Gleichen 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 Gleichen: the leader, Bell West Inc., 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 2015–2019. The rate centre is growing at a regular rather than explosive pace.

Dialling a Gleichen number

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

The numbering neighbourhood

Gleichen shares area codes 587, 403 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 Gleichen number tells you

A number attached to Gleichen tells you that its prefix was issued to a carrier for this rate centre in Alberta, most often Bell West Inc.. It does not tell you where the handset is today: a subscriber may have ported the number to any of the 5 carriers present here or to a VoIP service usable anywhere. 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 Gleichen: code 587-633 is recorded for Bell West Inc., so every 587-633-XXXX number (10,000 possible) descends from that assignment. “Gleichen, Alberta” there names a rate centre, not a municipality, and several area codes overlay it.

Every Gleichen prefix
