Thailand’s Personal Data Protection Act B.E. 2562 (2019) (PDPA) could soon see some important changes, as a draft bill to amend the PDPA has been introduced in the House of Representatives. The draft amendment is currently in the public consultation phase, with comments accepted from July 16 to August 15, 2026. If enacted in its current form, the amendment would make three key changes: expanding the government exemption to cover anticorruption operations, introducing a statutory definition of “government agency,” and restructuring the lawful bases for personal data processing to align with international standards. Background The PDPA has encountered several enforcement challenges since its implementation, including three core problems identified by the bill’s sponsors: (1) the current exemptions for government agencies do not cover anticorruption and misconduct-prevention operations; (2) the PDPA lacks a clear statutory definition of “government agency,” causing legal uncertainty as to which entities are covered; and (3) the existing framework for lawful bases of data processing does not align with international standards—particularly the multiple-lawful-bases system in the EU’s General Data Protection Regulation (GDPR)—making compliance inflexible for both government and private sector entities. Expanded Government Exemption The current PDPA exempts government agencies performing duties related to national security (including fiscal security), public safety, anti-money laundering, forensic science, and cybersecurity. The proposed amendment adds “prevention and suppression of corruption and misconduct” to this list of exempted functions. This would allow anticorruption bodies—most notably the National Anti-Corruption Commission (NACC), which is identified as a directly affected party—to collect, use, and disclose personal data without being subject to PDPA requirements when carrying out their duties. New Statutory Definition of “Government Agency” Notably, while the current PDPA use the term “government agency” in several provisions, the term is not comprehensively defined, creating potential uncertainty as to its scope. The draft bill therefore

Data protection officers (DPOs) have become a fixture of Thailand’s privacy compliance landscape since the Personal Data Protection Act B.E. 2562 (2019) (PDPA) took full effect and the Office of the Personal Data Protection Committee (PDPC) began requiring certain organizations to appoint them. On July 7, 2026, the Office of the PDPC presented draft guidance on DPOs as part of a public consultation on a series of draft personal data protection manuals and recommendations. The draft offers the clearest indication yet of how the regulator expects the DPO role to work in practice, addressing recurring implementation issues under the PDPA—including when an organization must appoint a DPO, how the DPO should operate independently, how to manage conflicts of interest, and how data subjects and regulators should be able to contact the DPO. Because it remains in draft, organizations have an opportunity to weigh the practical implications now before the guidance is finalized. When a DPO Must Be Appointed The draft guidance clarifies the triggers for mandatory DPO appointment, including: Regular and systematic monitoring of personal data or systems on a large scale, such as tracking, analyzing, or predicting behavior, attitudes, or individual characteristics. Core activities involving large-scale processing of sensitive personal data, such as health data, biometric data, or criminal records. Certain foreign-organization representative arrangements. Public-sector coverage under relevant notifications identifying government entities that must appoint a DPO. Processing involving 100,000 or more data subjects may be considered large-scale. The guidance also contemplates voluntary DPO appointment for organizations that wish to raise their privacy governance standards, and such organizations should still comply with the standards applicable to DPOs under the law. Independence and Reporting Lines The draft guidance identifies lack of DPO independence as a core risk because an ineffective or constrained DPO may be unable to raise deficiencies

On July 16, 2026, Thailand’s Personal Data Protection Committee (PDPC) published a notification in the Government Gazette establishing detailed rules governing data subjects’ right of access under section 30 of the Personal Data Protection Act B.E. 2562 (2019) (PDPA). The notification will take effect 60 days after publication—mid-September 2026—giving data controllers a limited window to bring their processes into compliance. Scope The notification covers requests to access or obtain copies of personal data and requests for disclosure of the source of data collected without consent. Data subjects may exercise their rights directly or through authorized representatives. Key Requirements Important requirements set by the notification include the following: Required request channels. Controllers must provide at least two request channels: direct submission at the business location and registered mail. Electronic channels are optional but, if offered, may also be used for fulfilling requests. Request contents. Requests must be in writing or in electronic form and include the data subject’s name, the preferred access method, details of the data requested, and the requester’s signature. Controllers may request additional identifying information as needed. Identity and authority verification. Controllers may require official identity documents for verification. Authorized representatives must provide authorization documents and identity documents for both the data subject and the representative. Alternative verification methods (e.g., digital authentication) are permitted if they do not unreasonably obstruct data subjects’ rights. Review and response timelines. Controllers must review requests within 15 days. If the request is incomplete, the controller must notify the requester and allow at least 15 days to correct deficiencies. If not corrected, the request may be treated as abandoned. Once verified, controllers must fulfill requests within 30 days, extendable by another 30 days for large-volume or complex requests with notice to the requester. Methods for providing access or copies. Controllers may fulfill

Thailand’s Office of the Personal Data Protection Committee (PDPC) published a series of draft guidance documents for public consultation on July 7, 2026. Issued under the Personal Data Protection Act B.E. 2562 (2019) (PDPA), the drafts address a range of compliance issues and offer insight into the regulator’s current enforcement priorities. This article examines two of those drafts: one on lawful bases for processing personal data, and another on marketing and direct marketing. Together, they reflect the Office of the PDPC’s evolving expectations on lawful-basis selection, accountability, and the use of personal data in marketing. Organizations operating in Thailand should assess the practical implications now, before the guidance is finalized. Lawful Bases: A Structured Selection Process The draft guidance on lawful bases introduces a systematic five-step process for selecting an appropriate lawful basis for each processing activity. Organizations are expected to: Identify the processing activity involved. Assess the appropriate lawful basis. Evaluate whether the data is necessary for the processing. Conduct a legitimate interest assessment (LIA) where applicable. Ensure transparency through privacy notices. The guidance provides practical explanations and examples for each lawful basis under section 24 of the PDPA—including archiving, research, statistics, vital interests, contractual necessity, legal obligation, public task, legitimate interests, and consent—as well as the bases applicable to sensitive personal data under section 26. The aim is to promote more consistent and accurate lawful-basis selection across public- and private-sector organizations. A recurring theme throughout the guidance is that organizations should select the lawful basis that most accurately reflects the actual purpose and circumstances of the processing activity. The guidance cautions against treating consent as a default or catch-all basis where another lawful basis is more appropriate. For processing based on legitimate interests, organizations should conduct and document an LIA. Processing involving sensitive personal data may require
