How the allocation was built up

Aliant Telecom (NF) is the only carrier ever recorded for Black Duck Cove: no competitor has obtained a prefix here. A single-carrier rate centre is typical of small communities where only the incumbent ever built a network.

  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.

    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.
