Unlicensed Money Lending Messages

Licensed moneylenders can only advertise on their website and business premises. If you receive SMSes or WhatsApp messages from loansharks:

  • a) Do not reply or interact with the sender.
  • b) Notify the Police via i-Witness.
  • c) Report the number as “spam” and block it.

You may also call the National Crime Prevention Council’s X-Ah Long hotline at 1800-924-5664 to report loanshark activities anonymously.

Robo Calls

  • Do not answer calls from unknown numbers. 
  • If you happen to answer such a call, hang up immediately. Do not reply to any question or respond to instructions to press any button on your phone. 
  • Never give out personal data such as your NRIC number, bank account number or any other identifying information in response to unexpected or suspicious calls.
  • If you get a call from someone who says they represent a company or a government agency, verify the authenticity of the call. Hang up and call the organisation’s phone number on your account statement or the organisation’s website. 
  • Do not divulge information under pressure.

Tools Available

  • The ScamShield app blocks known scam callers in a list managed by National Crime Prevention Council and the Police. It also uses an on-device algorithm to filter SMSes sent by unknown persons to the junk folder.
  • Consider using other third party apps with similar functions to block unwanted calls and messages, e.g. Messages and Phone by Google, Calls Blacklist, Hiya, Call Control.
