Stay Alert to and Identification of Suspicious Calls

OFCA has been working closely with telecommunications service providers and law enforcement agencies to devise guidelines and codes of practice, while telecommunications service providers are also requested to implement various technical measures in combating fraudulent calls and messages delivered through telecommunications networks:

  • Calling numbers with a "+" sign as a prefix displayed on mobile phones indicate that the calls originate from outside Hong Kong
  • Local mobile service providers are sending voice alert or text alert for incoming calls with caller number prefixed with "+852" to raise public awareness of suspicious calls originating from outside Hong Kong.
  • Telecommunications service providers identify and block at the source suspicious calls originating from outside Hong Kong with caller number prefixed with "+852" (for example, an incoming call with a local fixed caller number prefixed with "+852").
  • Local mobile service providers monitor the calls originating from their networks and systems. They shall take appropriate actions to suspend the relevant telecommunications services of the telephone numbers if suspicious scam call patterns are identified.
  • With OFCA’s coordination, telecommunications service providers shall block or suspend services of the telephone numbers suspected to be involved in deception cases based on the information provided by the Police and prevent users from accessing suspicious fraudulent websites.

Even if the caller number display has no "+" sign and shows an 8-digit Hong Kong phone number, it may still be a scam call. Members of the public should also stay highly vigilant to calls made from local caller numbers so as to avoid falling victim to deception.
