Douglas Lake’s share of its area codes

Within area code 250, Douglas Lake accounts for only 1 of 781 prefixes (0.1%): the code is dominated by Victoria and spread over 268 rate centres. Within area code 672, Douglas Lake accounts for only 1 of 321 prefixes (0.3%): the code is dominated by Vancouver and spread over 109 rate centres. Within area code 778, Douglas Lake 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

ISP Telecom Inc. holds the largest share at 1 prefixes, 33.3% of the total, ahead of 2 other carriers. Code by code: TELUS is the only holder in 250; ISP Telecom Inc. is the only holder in 672; Navigata Communications Limited is the only holder in 778. No carrier holds prefixes in every one of Douglas Lake’s 3 area codes, while 3 appear in just one.

Wireless and wireline

None of Douglas Lake’s holders carries a mobility brand in its registered name: all 3 prefixes belong to wireline or wholesale carriers, among them ISP Telecom Inc, Navigata Communications Limited and TELUS. A call showing a Douglas Lake number therefore nominally comes from a landline, cable or VoIP platform rather than a locally assigned cellphone.

How the allocation was built up

Douglas Lake’s dated assignments run from 2013 to 2022. The busiest period was 2010–2014, when 1 prefixes went to 1 carrier. 1 prefixes (33%) 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.

Douglas Lake’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 2013. The most recent arrivals are ISP Telecom Inc. (2022) and Navigata Communications Limited (2013), a sign that new carriers are still asking for numbers in Douglas Lake.

Douglas Lake has just 3 prefixes (30,000 numbers): a very small rate centre, typical of a village or rural area served by a single switching office.

No single carrier dominates Douglas Lake: the leader, ISP Telecom Inc., holds only 33.3% of the prefixes against 2 competitors, a sign of a highly fragmented market where cable companies, mobility brands and VoIP providers weigh as much as the incumbent.

Growth is recent: 50.0% of the dated prefixes were assigned in the last ten years, peaking in 2010–2014. Douglas Lake is among the rate centres where demand for numbers is still rising quickly.

Dialling a Douglas Lake number

Douglas Lake is served by 3 overlaid area codes (250, 672 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

Douglas Lake shares area codes 250, 672 and 778 with at least 20 other rate centres, including Vancouver, Victoria, Kelowna, New Westminster, Abbotsford, South Kamloops, Nanaimo and Prince George. The largest of them, Vancouver, holds 255 prefixes in 672 and 778; the smallest on the list, Campbell River, has just 17.

What a Douglas Lake number tells you

A number attached to Douglas Lake tells you that its prefix was issued to a carrier for this rate centre in British Columbia, most often ISP Telecom Inc.. It does not tell you where the handset is today: a subscriber may have ported the number to any of the 3 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 Douglas Lake: code 672-560 is recorded for ISP Telecom Inc., so every 672-560-XXXX number (10,000 possible) descends from that assignment. “Douglas Lake, British Columbia” there names a rate centre, not a municipality, and several area codes overlay it.

Had a call from a Douglas Lake 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.

4. Forward suspicious texts to 7726

   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.
