How the Do Not Call (DNC) Registry Protects You
Under Singapore's Personal Data Protection Act (PDPA), organizations are strictly prohibited from sending telemarketing messages (via voice calls, SMS, or fax) to Singapore numbers registered on the national Do Not Call (DNC) Registry, unless they have obtained your clear and unambiguous consent.
Before initiating any commercial telemarketing, companies must verify their list against the DNC Registry. Failing to do so or ignoring a consumer's registration can result in severe financial penalties of up to S$10,000 per violation. Serious data protection breaches under the PDPA can cost firms up to S$1 million or 10% of their annual turnover in Singapore, whichever is higher.

The Role of IMDA and the SMS Sender ID Registry (SSIR)
To combat the massive surge of smishing (SMS phishing), the Infocomm Media Development Authority (IMDA) has put in place some of the strictest messaging rules in the world.
The SSIR System
All organizations sending commercial SMS with Alphanumeric Sender IDs (like brand names) must register with the Singapore SMS Sender ID Registry (SSIR).
"Likely-SCAM" Marker
Unregistered SMS attempting to use brand names are automatically blocked by local telcos or prominently marked as "Likely-SCAM" to protect recipients.

Local Scams in Singapore
While DNC rules bind legitimate local companies, professional cybercriminals ignore these legal boundaries entirely. In Singapore, some of the most dangerous, highly localized scams include:
- Singpass Phishing: Fraudulent SMS with links pretending to require Singpass verification, leading to identity theft and CPF investment drain.
- PayNow / Bank Impersonation Scams: Deceptive phone calls representing IRAS (tax authority) or local banks (DBS, OCBC, UOB) claim that a transfer failed, urging victims to authorize PayNow transactions or provide OTPs.
- SingPost Parcel Scams: Delivery smishing claiming a parcel cannot be delivered until a processing fee is paid, gathering credit card details.
- GovTech / Government Official Spoofing: Automated robo-calls pretending to be police officers or government agents claiming you have committed an offense.
Always verify incoming requests independently. Government agencies and banks in Singapore will never ask for your Singpass credentials, bank passwords, or OTPs over a phone call or unverified message.
