Who holds these numbers

Code by code: in 250, TELUS Mobility leads with 2 of 6 prefixes ahead of 3 others; in 236, TELUS Mobility leads with 3 of 5 prefixes ahead of 2 others; in 672, TELUS Mobility leads with 3 of 5 prefixes ahead of 1 others; in 778, TELUS Mobility leads with 1 of 3 prefixes ahead of 2 others. 1 carrier holds prefixes in every one of 100 Mile House’s 4 area codes, while 4 appear in just one.

Wireless and wireline

13 of 100 Mile House’s 19 prefixes (68.4%) are held by carriers whose registered name marks a wireless business: TELUS Mobility, Rogers Communications Canada Inc. (Wireless) and Bell Mobility. That makes this a mostly mobile rate centre, which is typical of recent allocations: new prefixes go overwhelmingly to cellphones. This is a sort by name, not a licence lookup, and a mobile prefix may have been ported to another network since.

How the allocation was built up

100 Mile House’s dated assignments run from 2003 to 2025. The busiest period was 2015–2019, when 6 prefixes went to 3 carriers. 2 prefixes (11%) carry no date in the register: these are the historic pre-1999 assignments, the wireline bedrock of the rate centre. Since 2020 another 6 prefixes have been added, so the rate centre is still growing.

100 Mile House’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 Rogers Communications Canada Inc. (Wireless) in 2003. The most recent arrivals are TELUS (2019), Navigata Communications Limited (2016) and Shaw Telecom Inc. (2010), a sign that new carriers are still asking for numbers in 100 Mile House.

100 Mile House has only 19 prefixes, or 190,000 numbers: a small rate centre, where the arrival of a single new carrier visibly changes the landscape.

TELUS Mobility leads with 47.4% of the prefixes, but 6 competitors have set up in 100 Mile House: a market where the incumbent keeps the edge without exclusivity.

Demand remains steady: 35.3% of the dated prefixes go back to the last ten years, the most active period being 2015–2019. The rate centre is growing at a regular rather than explosive pace.

Dialling a 100 Mile House number

The largest of them, Vancouver, holds 397 prefixes in 236, 672 and 778; the smallest on the list, Campbell River, has just 22.

What a 100 Mile House number tells you

A number attached to 100 Mile House tells you that its prefix was issued to a carrier for this rate centre in British Columbia, most often TELUS Mobility. It does not tell you where the handset is today: most of 100 Mile House’s prefixes are mobile, and a cellphone keeps its number when its owner moves across the country. 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 100 Mile House: code 250-644 is recorded for TELUS Mobility, so every 250-644-XXXX number (10,000 possible) descends from that assignment. “100 Mile House, British Columbia” there names a rate centre, not a municipality, and several area codes overlay it.

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.
