Official contact tracers will never send you a recorded message, and will never ask you for any personal financial details or request for the transfer of money over the phone. If you receive such a call, call the Police at 1800-255-0000 or submit a report online at www.police.gov.sg/iwitness.
Official contact tracers call and ask you questions with the aim to provide you with necessary care and guidance. If MOH needs you to share your TraceTogether proximity data for contact tracing, they will seek your consent, and provide you with a code to match with a corresponding verification code on your app.
If you're unsure and want to verify authenticity of contact tracer: Call MOH at 6325-9220
Updates on 24 March:
We are aware that there is a scam call going around — playing a recorded message saying they're from MOH, and asking users to press "9".
Official contact tracers will not play recorded messages to you over the phone.
If you receive such calls, let the Police know. Thank you for helping to stop these scams! :)
