Celista’s share of its area codes

Within area code 250, Celista accounts for only 1 of 781 prefixes (0.1%): the code is dominated by Victoria and spread over 268 rate centres. Within area code 778, Celista accounts for only 1 of 779 prefixes (0.1%): the code is dominated by Vancouver and spread over 159 rate centres.

Who holds these numbers

Shaw Telecom Inc. holds the largest share at 1 prefixes, 50.0% of the total, ahead of 1 other carrier. Code by code: TELUS is the only holder in 250; Shaw Telecom Inc. is the only holder in 778. No carrier holds prefixes in every one of Celista’s 2 area codes, while 2 appear in just one.

Wireless and wireline

None of Celista’s holders carries a mobility brand in its registered name: all 2 prefixes belong to wireline or wholesale carriers, among them Shaw Telecom Inc and TELUS. A call showing a Celista number therefore nominally comes from a landline, cable or VoIP platform rather than a locally assigned cellphone.

How the allocation was built up

Celista’s dated assignments run from 2012 to 2012. The busiest period was 2010–2014, when 1 prefixes went to 1 carrier. 1 prefixes (50%) 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 Celista is flat.

Celista’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 Shaw Telecom Inc. in 2012. The most recent arrivals are Shaw Telecom Inc. (2012), a sign that new carriers are still asking for numbers in Celista.

Celista has just 2 prefixes (20,000 numbers): a very small rate centre, typical of a village or rural area served by a single switching office.

Shaw Telecom Inc. leads with 50.0% of the prefixes, but 1 competitors have set up in Celista: 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 2010–2014, and 1 prefixes go back to the undated monopoly era. New Celista numbers mostly come out of blocks that were assigned long ago.

Dialling a Celista number

Celista is served by 2 overlaid area codes (250 and 778). A 778 number is no more “out of town” than a 250 one; from abroad, dial +1 and the full ten digits.

The numbering neighbourhood

Celista shares area codes 250 and 778 with at least 20 other rate centres, including Vancouver, Victoria, Kelowna, New Westminster, Nanaimo, South Kamloops, Prince George and Vernon. The largest of them, Vancouver, holds 172 prefixes in 778; the smallest on the list, Parksville, has just 16.

What a Celista number tells you

A number attached to Celista tells you that its prefix was issued to a carrier for this rate centre in British Columbia, most often Shaw Telecom Inc.. It does not tell you where the handset is today: a subscriber may have ported the number to any of the 2 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 British Columbia area code is easy to borrow to look local.

Reading a register entry for Celista: code 778-534 is recorded for Shaw Telecom Inc., so every 778-534-XXXX number (10,000 possible) descends from that assignment. “Celista, British Columbia” there names a rate centre, not a municipality, and several area codes overlay it.
