Singaporean Phone Number Lookup (+65)

Unknown calls from Singapore

Scam calls are a serious public concern in Singapore, and many residents now screen unfamiliar numbers as a matter of habit. Fraudsters impersonate government officials, bank staff and even friends, and job scams promising easy online income are widespread. To help, overseas calls are shown with a plus sign, so a caller claiming to be local but appearing as +65 from abroad is a red flag. Legitimate unknown calls still happen often — couriers, clinics, property agents and recruiters among them. Looking up an 8- or 9-starting mobile or a 6-starting landline helps you decide whether to answer or call back.

Common phone scams in Singapore

Government official impersonation

Callers claim to be from the police, MAS, MOH or another agency and say you are linked to a crime or money laundering. They may transfer you to a fake ‘officer’ and pressure you to move money for investigation. Government officials will never ask you to transfer money or reveal banking credentials over the phone.

‘Guess who’ friend impersonation

A caller or WhatsApp message from an unknown number says ‘guess who’ and pretends to be a friend or relative with a new number. Later they ask for an urgent loan. Before transferring anything, call the person on the number you already have saved to confirm it is really them.

Online job scams

Messages offer well-paid, part-time work such as rating products or boosting sales online. Early small payouts build trust, then you are asked to deposit increasingly large sums to ‘unlock’ commissions. Genuine employers don’t require you to pay to get paid.
