Singapore: when a breach is notifiable

Part 6A of the Personal Data Protection Act 2012 sets the breach rules 1. Under section 26B, a data breach is notifiable if it results in, or is likely to result in, significant harm to an affected individual, or if it is, or is likely to be, of a significant scale 1. A breach involving prescribed personal data is deemed to result in significant harm 1.

The Personal Data Protection (Notification of Data Breaches) Regulations 2021 came into operation on 1 February 2021 2. Regulation 4 sets the prescribed number of affected individuals for significant scale at 500 2. Regulation 3 lists the classes of data that are deemed to cause significant harm, including account identifiers held with banks and finance companies 2.

Singapore: the notice steps

  • Assess the breach under section 26C 1.
  • Notify the Commission as soon as practicable, and in any case no later than 3 calendar days after the day of the assessment, under section 26D(1) 1.
  • Notify each affected individual under section 26D(2), subject to the exceptions in section 26D(5) 1.
  • Notice to individuals is not needed where the organisation took action after the assessment, or had technological measures in place before the breach, that make significant harm unlikely, under section 26D(5) 1.

Singapore: the PDPC reporting route

The PDPC published a reporting guide for Data Protection Officers on 22 April 2026 5. It explains how to decide whether a breach is notifiable, how to meet the three-day deadline and how to report using the Commission's process and its C.A.R.E. framework 5. The PDPC offers a self-assessment tool to test whether a breach is notifiable and an e-service form to submit the notification 5.
