|---|---|---|---|---|
| TELUS | 2 | — | — | 2 |

Wireless and wireline
None of Grand Centre’s holders carries a mobility brand in its registered name: all 5 prefixes belong to wireline or wholesale carriers, among them TELUS, Bell West Inc, Bragg Communications Inc and Distributel. A call showing a Grand Centre number therefore nominally comes from a landline, cable or VoIP platform rather than a locally assigned cellphone.
How the allocation was built up
Grand Centre’s dated assignments run from 2009 to 2018. The busiest period was 2005–2009, when 1 prefixes went to 1 carrier. 2 prefixes (40%) 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 Grand Centre is flat.
Grand Centre’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 Bragg Communications Inc. in 2009. The most recent arrivals are Distributel (2018), Bell West Inc. (2014) and Bragg Communications Inc. (2009), a sign that new carriers are still asking for numbers in Grand Centre.
Grand Centre has just 5 prefixes (50,000 numbers): a very small rate centre, typical of a village or rural area served by a single switching office.
TELUS leads with 40.0% of the prefixes, but 3 competitors have set up in Grand Centre: a market where the incumbent keeps the edge without exclusivity.
Allocation is mature: only 0.0% of the dated prefixes are less than ten years old, most having been handed out in 2005–2009, and 2 prefixes go back to the undated monopoly era. New Grand Centre numbers mostly come out of blocks that were assigned long ago.
| Period | Prefixes | Carriers |
|---|---|---|
| 2005–2009 | 1 | 1 |
| 2010–2014 | 1 | 1 |
| 2015–2019 | 1 | 1 |

What a Grand Centre number tells you
A number attached to Grand Centre tells you that its prefix was issued to a carrier for this rate centre in Alberta, most often TELUS. 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 an Alberta area code is easy to borrow to look local.
Reading a register entry for Grand Centre: code 780-594 is recorded for TELUS, so every 780-594-XXXX number (10,000 possible) descends from that assignment. “Grand Centre, Alberta” there names a rate centre, not a municipality, and several area codes overlay it.

Had a call from a Grand Centre number?
No clear pattern in reports on these numbers yet. If a call worried you:
- 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.
- 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.
- 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 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.

An allocation says who was issued the prefix, not who serves the number today: numbers can be ported between carriers, and caller ID can be spoofed outright.
