Thailand Approves Draft Royal Decree on Inter-Agency Personal Data Sharing
On 5 May 2026, the Thai Cabinet approved in principle the Draft Royal Decree on the Disclosure of Personal Data under the Control of State Agencies to Other State Agencies (B.E. .…) (the “Draft Royal Decree”), as proposed by the Office of the Council of State.
The Draft Royal Decree represents a significant development in Thailand’s digital government agenda and is expected to substantially expand the capacity of state agencies to exchange and process personal data across the public sector.
The measure seeks to establish a centralized legal framework for inter-agency data sharing in support of more integrated and efficient public administration. It also forms part of Thailand’s broader transition toward a digital and data-driven government, with the stated aims of strengthening welfare systems, improving regulatory coordination, and streamlining public services.
Background and Policy Objectives
Historically, personal data held by Thai government agencies has remained fragmented across separate authorities and databases. This fragmentation has frequently resulted in duplicated procedures, inconsistent records, delays in public service delivery, and constraints on data-driven policymaking.
The Draft Royal Decree seeks to address these challenges by requiring state agencies to disclose relevant personal data to other government agencies upon request, where such disclosure serves public administration purposes. The stated objective is to facilitate more effective governance while reducing administrative burdens on citizens and businesses.
The Draft Royal Decree also seeks to balance greater data accessibility with robust safeguards relating to confidentiality, cybersecurity, and data protection compliance.
Key Provisions of the Draft Royal Decree
1. Mandatory Disclosure Between State Agencies
Under the Draft Royal Decree, state agencies would be required to disclose personal data under their control to other state agencies upon request. The proposed framework is intended to facilitate:
- inter-agency data linkage;
- integrated digital government services;
- more efficient welfare administration; and
- evidence-based policymaking.
This would represent a material departure from the current framework, under which data sharing between agencies is often limited, fragmented, or governed by sector-specific regulations.
2. Restrictions on Further Disclosure
The Draft Royal Decree imposes obligations on receiving agencies to safeguard any personal data disclosed to them. In particular, receiving agencies must:
- maintain the confidentiality of the disclosed data; and
- refrain from disclosing such data to external parties, whether public or private.
These requirements are designed to establish a controlled framework governing the circulation of personal data within the public sector.
3. Security and Cybersecurity Compliance
The handling and protection of shared data must comply with:
- criteria prescribed by the Official Information Commission (“OIC”); and
- applicable cybersecurity standards.
The inclusion of cybersecurity obligations reflects growing regulatory concern regarding unauthorized access, data breaches, and the risks associated with large-scale government data integration.
Interaction with Thailand’s PDPA
One of the most significant legal implications of the Draft Royal Decree lies in its interaction with the Personal Data Protection Act B.E. 2562 (2019) (“PDPA”). The Draft Royal Decree appears intended to qualify as “other law” within the meaning of Section 21(2) of the PDPA. If enacted, this would permit state agencies to process personal data for purposes beyond those originally notified to data subjects, provided that such processing is authorized under the Royal Decree.
In practice, this may operate as a statutory exception to the PDPA’s purpose limitation principle in the context of inter-agency data sharing within the public sector, thereby granting state agencies broader authority to reuse, exchange, and integrate personal data where necessary for public administration and service delivery.
Expected Impact
The Draft Royal Decree is expected to advance Thailand’s transition toward a more integrated digital government by:
- reducing duplication across government databases;
- streamlining administrative procedures;
- improving access to public services;
- enhancing transparency and regulatory oversight;
- supporting anti-corruption initiatives; and
- enabling more effective monitoring of informal economic activity.
For businesses and individual citizens, the proposed framework may reduce the need for repetitive document submissions and administrative formalities when dealing with government authorities.
At the same time, the expanded ability of state agencies to access and process personal data is likely to attract increased scrutiny with respect to proportionality, data governance standards, inter-agency oversight mechanisms, and the adequacy of cybersecurity safeguards.
The Draft Royal Decree may accordingly prove to be a defining development in Thailand’s evolving public-sector data governance landscape, particularly as government agencies continue to expand their digital infrastructure and interconnected service delivery capabilities.
Key Takeaways
- Thailand is advancing toward a mandatory inter-agency data sharing framework within the public sector.
- State agencies may be legally required to disclose personal data to other government authorities upon request.
- Receiving agencies must maintain confidentiality and comply with applicable cybersecurity and data protection standards.
- The Draft Royal Decree may operate as an “other law” exception under the PDPA, permitting broader processing of personal data by state agencies.
- The proposed framework forms part of Thailand’s broader digital government strategy, aimed at improving administrative efficiency, regulatory coordination, and public service delivery.
