South Slocan’s share of its area codes

Within area code 236, South Slocan 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, South Slocan 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, South Slocan 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

Navigata Communications Limited holds the largest share at 1 prefixes, 33.3% of the total, ahead of 2 other carriers. Code by code: Navigata Communications Limited is the only holder in 236; TELUS is the only holder in 250; Shaw Telecom Inc. is the only holder in 778. No carrier holds prefixes in every one of South Slocan’s 3 area codes, while 3 appear in just one.

Wireless and wireline

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

How the allocation was built up

South Slocan’s dated assignments run from 2013 to 2016. 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. No prefix has been added since 2020: demand for numbers in South Slocan is flat.

South Slocan’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 2013. The most recent arrivals are Navigata Communications Limited (2016) and Shaw Telecom Inc. (2013), a sign that new carriers are still asking for numbers in South Slocan.

South Slocan 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 South Slocan: the leader, Navigata Communications Limited, 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.

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 South Slocan numbers mostly come out of blocks that were assigned long ago.

Dialling a South Slocan number

South Slocan is served by 3 overlaid area codes (236, 250 and 778). A 778 number is no more “out of town” than a 236 one; from abroad, dial +1 and the full ten digits.

The numbering neighbourhood

South Slocan shares area codes 236, 250 and 778 with at least 20 other rate centres, including Vancouver, Victoria, Kelowna, New Westminster, Nanaimo, South Kamloops, Prince George and Abbotsford. The largest of them, Vancouver, holds 314 prefixes in 236 and 778; the smallest on the list, North Vancouver, has just 21.

What a South Slocan number tells you

A number attached to South Slocan 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 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 South Slocan: code 236-291 is recorded for Navigata Communications Limited, so every 236-291-XXXX number (10,000 possible) descends from that assignment. “South Slocan, British Columbia” there names a rate centre, not a municipality, and several area codes overlay it.

Had a call from a South Slocan 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.
