19/01/2026 13:00

On 31 December 2025, Decree No. 356/2025/ND-CP guiding the implementation of the Personal Data Protection Law (Decree 356) was officially issued by the Government. Decree 356 came into effect on 1 January 2026 and replaces Decree No. 13/2023/ND-CP dated 17 April 2023 of the Government on personal data protection (Decree 13), thereby contributing to the effective implementation of the Personal Data Protection Law and ensuring consistency across the legal framework on personal data protection. In this Legal Update, we present notable provisions of Decree 356 and compare them with those of Decree 13, thereby highlighting key changes and their potential implications for businesses.
1. Implementation of data subject rights
Compared to Decree 13, Decree 356 introduces specific procedures and timelines for the data controller, and the data controller and processor to respond and implement data subject requests.
Specifically, Decree 356 clearly requires that the data controller, and data controller and processor must respond within two (2) working days from the date of receipt of a request and provide information on the procedures for fulfilling such requests. While Decree 13 required that data subject requests be fulfilled within seventy-two (72) hours of receipt of such requests, Decree 356 establishes different processing times for each type of data subject request, including provisions for extensions where necessary and reasonable, as detailed in the table below.
Data subject requests | Decree 13 | Decree 356 | ||
By data controller/data controller and processor itself | If the data processor or the third party is involved | Extension period (if any, permitted once only) | ||
Withdrawal of consent, restriction, or objection to processing | Seventy-two (72) hours | Fifteen (15) days | 20 days | Fifteen (15) days
|
Access, rectification, and provision of personal data | Ten (10) days | Fifteen (15) days
| Ten (10) days | |
Erasure of personal data | Twenty (20) days | Thirty (30) days | Twenty (20) days | |
Requests to implement solutions and measures to protect personal data | Not regulated | Fifteen (15) days
| Not applicable | Fifteen (15) days |

(i) Journalism and communication activities in accordance with the law;

(iii) Emergencies where it is necessary to transfer personal data across borders to protect life, health, or property safety of individuals or to perform tasks and obligations as prescribed by law;

(v) Provision of personal data across borders for contract conclusion or for carrying out procedures related to cross-border transportation, logistics, remittance, payment, accommodation, visa applications, or scholarship applications.
5. Personal data processing services
This is a new provision introduced by Decree 356. Accordingly, data processing services include, among others, credit scoring services, personal data encryption services, and automated data processing using AI, big data, blockchain, or the metaverse. These services are subject to strict conditions and are required to complete relevant procedures for obtaining certificates of eligibility for providing personal data processing services.
