Giscome’s share of its area codes

Within area code 236, Giscome accounts for only 1 of 745 prefixes (0.1%): the code is dominated by Vancouver and spread over 269 rate centres. Within area code 250, Giscome accounts for only 1 of 781 prefixes (0.1%): the code is dominated by Victoria and spread over 268 rate centres.

Who holds these numbers

Navigata Communications Limited holds the largest share at 1 prefixes, 50.0% of the total, ahead of 1 other carrier. Code by code: Navigata Communications Limited is the only holder in 236; TELUS is the only holder in 250. No carrier holds prefixes in every one of Giscome’s 2 area codes, while 2 appear in just one.

Wireless and wireline

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

How the allocation was built up

Giscome’s dated assignments run from 2016 to 2016. The busiest period was 2015–2019, 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 Giscome is flat.

Giscome’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 Navigata Communications Limited in 2016. The most recent arrivals are Navigata Communications Limited (2016), a sign that new carriers are still asking for numbers in Giscome.

Giscome 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.

Navigata Communications Limited leads with 50.0% of the prefixes, but 1 competitors have set up in Giscome: 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 2015–2019, and 1 prefixes go back to the undated monopoly era. New Giscome numbers mostly come out of blocks that were assigned long ago.

Dialling a Giscome number

Giscome is served by 2 overlaid area codes (236 and 250). A 250 number is no more “out of town” than a 236 one; from abroad, dial +1 and the full ten digits.

The numbering neighbourhood

Giscome shares area codes 236 and 250 with at least 20 other rate centres, including Vancouver, Victoria, Kelowna, Nanaimo, South Kamloops, Prince George, Vernon and Penticton. The largest of them, Vancouver, holds 142 prefixes in 236; the smallest on the list, Williams Lake, has just 12.

What a Giscome number tells you

A number attached to Giscome tells you that its prefix was issued to a carrier for this rate centre in British Columbia, most often Navigata Communications Limited. 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 Giscome: code 236-396 is recorded for Navigata Communications Limited, so every 236-396-XXXX number (10,000 possible) descends from that assignment. “Giscome, British Columbia” there names a rate centre, not a municipality, and several area codes overlay it.

Had a call from a Giscome number?

No clear pattern in reports on these numbers yet. If a call worried you:

1. Call back on a number you trust

   If a caller says they are your bank, the Canada Revenue Agency, a courier or your phone company, hang up and call the organization on the number from its website or your statement, never the number that called you. Caller ID can be faked.

2. Report the fraud

   Report the call or text to the Canadian Anti-Fraud Centre online or at 1-888-495-8501. If you lost money or gave out personal details, tell your bank first, then your local police.

3. Register on the National Do Not Call List

   Registering a landline or mobile on the National DNCL is free. Registered charities, political parties, newspapers and companies you already do business with may still call.

   Forward a scam or spam text to 7726 (SPAM on the keypad). It's free, and your carrier uses it to block the sender. Don't tap links or reply.
