Do-Not-Call and Consent: Marketing Compliance for SG Websites

Collecting contacts through your website is only half the story. In Singapore, how you then market to them is governed by the PDPA and the Do Not Call Registry. Getting this right protects you and respects your customers. This is a plain-English overview, not legal advice.

The Do Not Call Registry

The DNC Registry lets people opt out of marketing messages to their Singapore phone numbers. Before sending marketing calls, texts or faxes to a Singapore number, organisations generally must check the relevant DNC register unless they have clear, unambiguous consent that meets the rules.

If you run phone or SMS marketing, build the DNC check into your process rather than treating it as an afterthought.

Consent for marketing

Under the PDPA, using personal data for marketing needs a proper basis. The cleanest approach is clear opt-in consent at the point of collection, with a plain explanation of what people are signing up for, and an easy way to opt out later.

Pre-ticked boxes and vague catch-all permissions do not meet the standard.

Building it into your website

• Use clear, specific opt-in language on signup forms, not pre-ticked boxes.
• Record what each person consented to and when.
• Provide an easy unsubscribe in every marketing message.
• Check the DNC register before phone or SMS marketing to Singapore numbers.
• Keep your privacy policy current on how you use contact data.

Why it is worth doing well

Beyond avoiding penalties, respectful marketing performs better. People who genuinely opted in are more engaged, and a clean, consented list is worth more than a large unconsented one.
