FAQs about Universal Call Blocking

  • What is Universal Call Blocking (UCB)?
    Universal Call Blocking is a CRTC mandate (CRTC decision 2018-484) to block all incoming voice calls that have malformed calling line ID information. This applies to all Canadian service providers. Malformed calling line ID information contains telephone numbers that do not comply with North American or International numbering plans.
  • How will Universal Call Blocking affect me?
    Universal Call Blocking will prevent you from receiving calls with calling line IDs that have malformed numbers.
  • How does Universal Call Blocking work?
    Any incoming call with a malformed calling line ID will likely be blocked by the destination party’s service provider.
  • How can I tell if a number is malformed?
    Generally, any number that does not comply with the North American Numbering Plan or international standards will be blocked. 000-000-0000, 111-111-1111 or numbers with more than 15 digits are examples of non-compliant numbers.

How to Protect Yourself from Caller ID Spoofing and Spam Calls

Caller ID spoofing is when a caller deliberately changes the information transmitted to your caller ID display to disguise their identity, sometimes for unethical reasons.

General safety and prevention tips

Keep these in mind for your protection while using your home or mobile phone.

  • Don’t give away your personal information
  • If you do answer a call from an unknown number, ask for a number you can call them back on.
  • Don’t call back or answer calls from unknown numbers.
  • If the call is at all suspicious, it is probably is a scam.
  • If they say they are calling regarding one of your accounts, do not hesitate to ask for further information and call the firm back through the firm’s general switchboard number.
  • Be aware that a Caller ID showing a “local” number no longer means it is necessarily a local caller. If the caller claims to be from a legitimate company or organization, hang up and call them back using a valid number found on their website or on your latest bill if you do business with them.
  • If you answer and the caller (often a recording) asks you to press a button to stop receiving calls, or asks you to say “yes” in response to a question, just hang up. Scammers often use these tricks to identify, and then target, live respondents, or to use your “yes” to apply unauthorized charges to your bill.
  • If you answer and the caller asks for payment using a gift card, it’s likely a scam. Legitimate organizations like law enforcement will not ask for payment with a gift card.
  • If you have lost money as a result of a scam call, contact your local law enforcement agency for assistance.
  • Use caution if you are being pressured for information immediately.
