Who holds these numbers

MTS Inc. holds the largest share at 6 prefixes, 24.0% of the total, ahead of 15 other carriers. Code by code: in 204, MTS Inc. leads with 5 of 14 prefixes ahead of 8 others; in 431, Bell West Inc. leads with 2 of 5 prefixes ahead of 3 others; in 365, Distributel leads with 1 of 4 prefixes ahead of 3 others; Rogers Communications Canada Inc. (Cable) is the only holder in 742; Bell Canada is the only holder in 905. No carrier holds prefixes in every one of Selkirk’s 5 area codes, while 13 appear in just one.

Wireless and wireline

6 of Selkirk’s 25 prefixes (24.0%) are held by carriers whose registered name marks a wireless business: Bell Mobility, TELUS Mobility, Fido Solutions Inc and Rogers Communications Canada Inc. (Wireless). Wireline prefixes still outnumber them, carried by MTS Inc, Bell West Inc, TELUS Integrated Communications and Bell Canada. 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

Selkirk’s dated assignments run from 2000 to 2025. The busiest period was 2010–2014, when 7 prefixes went to 6 carriers. 4 prefixes (16%) carry no date in the register: these are the historic pre-1999 assignments, the wireline bedrock of the rate centre. Since 2020 another 5 prefixes have been added, so the rate centre is still growing.

Selkirk’s oldest prefixes, the ones the register leaves undated, belong to MTS Inc and Bell Canada: these carriers made up the landscape before competition arrived. The first dated assignment went to MTS Inc. in 2000. The most recent arrivals are Rogers Communications Canada Inc. (Cable) (2025), Fibernetics Corporation (2022) and TekSavvy Solutions Inc (2020), a sign that new carriers are still asking for numbers in Selkirk.

Selkirk has only 25 prefixes, or 250,000 numbers: a small rate centre, where the arrival of a single new carrier visibly changes the landscape.

No single carrier dominates Selkirk: the leader, MTS Inc., holds only 24.0% of the prefixes against 15 competitors, a sign of a highly fragmented market where cable companies, mobility brands and VoIP providers weigh as much as the incumbent.

Demand remains steady: 23.8% of the dated prefixes go back to the last ten years, the most active period being 2010–2014. The rate centre is growing at a regular rather than explosive pace.

Dialling a Selkirk number

Selkirk is served by 5 overlaid area codes (204, 431, 365, 742 and 905). A 905 number is no more “out of town” than a 204 one; from abroad, dial +1 and the full ten digits.

The numbering neighbourhood

Selkirk shares area codes 204, 431, 365, 742 and 905 with at least 20 other rate centres, including Winnipeg, Hamilton, Brampton, Oshawa, St. Catharines-Thorold, Markham, Cooksville and Oakville. The largest of them, Winnipeg, holds 394 prefixes in 204 and 431; the smallest on the list, Richmond Hill, has just 25.

What a Selkirk number tells you

A number attached to Selkirk tells you that its prefix was issued to a carrier for this rate centre in Manitoba, most often MTS Inc.. It does not tell you where the handset is today: a subscriber may have ported the number to any of the 16 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 Manitoba area code is easy to borrow to look local.

Reading a register entry for Selkirk: code 204-482 is recorded for MTS Inc., so every 204-482-XXXX number (10,000 possible) descends from that assignment. “Selkirk, Manitoba” there names a rate centre, not a municipality, and several area codes overlay it.

Had a call from a Selkirk 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.

   Report to the Canadian Anti-Fraud Centre ↗

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.
