Hemlock Valley’s share of its area codes

Within area code 236, Hemlock Valley accounts for only 2 of 745 prefixes (0.3%): the code is dominated by Vancouver and spread over 269 rate centres. Within area code 604, Hemlock Valley accounts for only 1 of 781 prefixes (0.1%): the code is dominated by Vancouver and spread over 43 rate centres. Within area code 672, Hemlock Valley accounts for only 1 of 321 prefixes (0.3%): the code is dominated by Vancouver and spread over 109 rate centres.

Who holds these numbers

Distributel holds the largest share at 1 prefixes, 25.0% of the total, ahead of 3 other carriers. Code by code: in 236, Distributel leads with 1 of 2 prefixes ahead of 1 others; TELUS is the only holder in 604; ISP Telecom Inc. is the only holder in 672. No carrier holds prefixes in every one of Hemlock Valley’s 3 area codes, while 4 appear in just one.

Wireless and wireline

None of Hemlock Valley’s holders carries a mobility brand in its registered name: all 4 prefixes belong to wireline or wholesale carriers, among them Distributel, Fibernetics Corporation, ISP Telecom Inc and TELUS. A call showing a Hemlock Valley number therefore nominally comes from a landline, cable or VoIP platform rather than a locally assigned cellphone.

How the allocation was built up

Hemlock Valley’s dated assignments run from 2016 to 2022. The busiest period was 2020–2024, when 2 prefixes went to 2 carriers. 1 prefixes (25%) carry no date in the register: these are the historic pre-1999 assignments, the wireline bedrock of the rate centre. Since 2020 another 2 prefixes have been added, so the rate centre is still growing.

Hemlock Valley’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 (2022), ISP Telecom Inc. (2022) and Distributel (2016), a sign that new carriers are still asking for numbers in Hemlock Valley.

Hemlock Valley has just 4 prefixes (40,000 numbers): a very small rate centre, typical of a village or rural area served by a single switching office.

No single carrier dominates Hemlock Valley: the leader, Distributel, holds only 25.0% of the prefixes against 3 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: 66.7% of the dated prefixes were assigned in the last ten years, peaking in 2020–2024. Hemlock Valley is among the rate centres where demand for numbers is still rising quickly.

Dialling a Hemlock Valley number

Hemlock Valley is served by 3 overlaid area codes (236, 604 and 672). A 672 number is no more “out of town” than a 236 one; from abroad, dial +1 and the full ten digits.

The numbering neighbourhood

Hemlock Valley shares area codes 236, 604 and 672 with at least 20 other rate centres, including Vancouver, New Westminster, Abbotsford, Richmond, North Vancouver, Aldergrove, Chilliwack and Victoria. The largest of them, Vancouver, holds 568 prefixes in 236, 604 and 672; the smallest on the list, Prince George, has just 15.

What a Hemlock Valley number tells you

A number attached to Hemlock Valley tells you that its prefix was issued to a carrier for this rate centre in British Columbia, most often Distributel. It does not tell you where the handset is today: a subscriber may have ported the number to any of the 4 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 Hemlock Valley: code 236-441 is recorded for Distributel, so every 236-441-XXXX number (10,000 possible) descends from that assignment. “Hemlock Valley, British Columbia” there names a rate centre, not a municipality, and several area codes overlay it.

Had a call from a Hemlock Valley 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.
