Thailand Issues New Rules on Data Subject Access Requests

Subscribe to Updates

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 requests by allowing inspection, providing document copies, or granting electronic access. If a request is submitted electronically, the response should also be electronic where possible.
  • Grounds for refusal or limitation. Controllers may refuse requests where permitted by law or court order, where compliance would harm third-party rights (including personal data, trade secrets, or IP), or where the request is manifestly unfounded or unreasonably burdensome. Controllers must provide data subjects with the reason for refusal in writing, and the refusal must be recorded in the controller’s records.
  • Allowable fees. Electronic access without special recording or delivery costs should generally be free. Where fees are permitted, they must be reasonable, not exceed actual costs, and comply with the schedule attached to the notification. Fee details must be disclosed to data subjects in advance of any requests.
  • Recordkeeping. Controllers must retain records of requests and responses for at least two years. Electronic recordkeeping is permitted.
  • Interaction with other laws. Where other laws impose access-related duties, controllers must comply with those laws while remaining consistent with this notification’s procedures.

Next Steps

Data controllers being subject to the PDPA, both onshore and offshore, should assess their current data access request handling procedures against the notification’s requirements, including whether they offer the mandatory request channels and can meet the prescribed timelines. Key actions include:

  • Conducting a gap analysis of existing procedures against the new requirements.
  • Updating privacy notices and internal policies to clearly communicate request channels, fee schedules, and processing timelines.
  • Implementing or updating request management systems to track requests, verification status, deadlines, and record retention.
  • Training relevant personnel, particularly data protection officers, customer service teams, and legal and compliance staff, on the new timelines and procedures.
  • Preparing template responses, including refusal notices with documented reasons, correction requests, and abandonment notifications.

Given the short compliance window, organizations that have not yet established formal data access request procedures should begin implementation promptly.

Thailand’s Personal Data Protection Committee (PDPC) has launched a public consultation period on a draft notification setting out criteria for data subject access requests (DSARs). The draft notification addresses practical uncertainties in handling DSARs by introducing standardized procedural requirements for data controllers. The consultation period runs from April 16 to May 15, 2026. The notification will enter into force 30 days from the date of its publication in the Government Gazette. Key Features of the Draft Notification The draft notification covers the following key areas: Scope of information subject to access. Data controllers must enable data subjects to access at least the following upon request: (1) personal data collected directly from them; (2) personal data obtained from other sources; and (3) the source of personal data obtained from other sources without consent. Information required under section 23 of the PDPA and information that must be recorded pursuant to section 39 of the PDPA—such as the categories of personal data collected and purposes of processing—must also be made available. Submission channels and formal requirements. Data controllers must provide at least in-person and postal channels for DSARs, while electronic or other channels are optional. Requests may be made either directly by the data subject or through an authorized representative, and must be signed and include sufficient identifying information, a preferred response method, and DSAR details. Identity verification documents (and proof of authority if the request is through a representative) are required, and additional documentation may be requested for verification or communication purposes. Data controllers may use different verification methods for DSARs submitted via electronic or other channels, provided this does not create undue obstacles to the exercise of data subject rights. Verification and response timelines. Data controllers must complete preliminary verification within seven business days of receiving a request. If a

Thailand has introduced new regulatory guidance requiring digital platform operators to adopt structured, transparent, and fair fee practices. On March 16, 2026, the Electronic Transactions Development Agency (ETDA) published Announcement No. DPS 2/2569, titled “Guidelines for Transparency and Fairness in Digital Platform Service Fee Determination,” issued under the Royal Decree on Digital Platform Service Business Operations B.E. 2565 (2022). The guidelines establish a framework governing how digital platform operators should set, disclose, and adjust fees charged to users and related service providers such as logistics and payment providers. Although framed as best-practice guidance rather than legally binding rules with explicit penalties, the guidelines carry regulatory weight under the royal decree and represent a significant step toward structured governance of digital platform fee practices in Thailand. The guidelines establish various transparency principles and divide fees into two distinct categories—compulsory and additional—with specific governance principles for each. Transparency Principles The guidelines recommend that digital platform operators adopt several transparency measures to ensure that users can fully understand the costs of using a platform. Fee catalog. All fees should be consolidated into a single, accessible location, which should include the fee name, definition, scope of covered services, calculation methodology, rate, billing period, and calculation examples. Minimum service disclosure. Operators should disclose the minimum service that users can expect, such as baseline visibility, product listing capabilities, access to transaction data, and back-end dashboard access. Price structure disclosure. Operators should disclose the categories of costs underlying their fees, such as system maintenance, cybersecurity, and operational costs. While exact cost figures need not be made public, operators should be able to provide numerical data to regulators upon request. Clear fee formulas. Fee calculations should be simple and easy to understand—for example, percentage of net sales, cost per order, or cost per product listing. Operators should

As digital commerce continues to reshape consumer behavior in Thailand, the Office of the Consumer Protection Board (OCPB) has been taking steps to review and update key regulations for online platforms. The OCPB has had a particular focus on addressing the risks posed by e-marketplace businesses—from misleading product information to fraudulent online transactions. Some of the regulator’s current legislative efforts related to Thailand’s labeling regulations as well as potential changes to the country’s law on direct sales and marketing. Proposed Changes to Consumer Protection Labeling Regulations On February 24, 2026, the OCPB convened a public hearing to review the Notification of the Committee on Labels re: Specification of Goods as Controlled Label Goods B.E. 2565 (2022) and its annex issued under the Consumer Protection Act. The closed-door session, which started the OPCD’s process of seeking feedback on the proposed changes, brought together representatives from government agencies, business operators, and consumer groups. The OCPB explained that its review of the labeling regulations aims to address regulatory gaps arising from evolving commercial practices, particularly the expansion of e-commerce and cross-border transactions. Authorities highlighted recurring issues involving product information that is unclear, incomplete, or potentially misleading in digital sales channels. The proposed revisions are intended to improve consumers’ access to accurate and complete product information, ensure that label disclosures remain relevant amid the growth of e-commerce, and strengthen protections against deceptive or misleading digital advertising. The review is being undertaken pursuant to the Consumer Protection Act B.E. 2522 (1979). As part of the initiative, the OCPB signaled a potential update to the categories of “controlled label products” as well as enhanced disclosure obligations for business operators, with the broader aim of promoting greater transparency, reinforcing operator accountability, and aligning Thailand’s labeling framework with current market conditions. The OCPB secretary general emphasized that

As part of its ongoing public consultation process for the development of new practical guidelines under the Personal Data Protection Act B.E. 2562 (2019) (PDPA), Thailand’s Personal Data Protection Committee (PDPC) held a two‑day public hearing on April 1–2, 2026. The hearing followed an online questionnaire and stakeholder engagement activities conducted in March 2026 and reflects the PDPC’s continued efforts to develop guidance that aligns international regulatory standards with Thai operational realities. The public hearing provided a forum for participants from both the public and private sectors to exchange views with the PDPC on the proposed guidance so that it responds to the needs of the business community while supporting effective and balanced enforcement of the PDPA. The PDPC emphasized that the consultation process is part of a wider policy objective to build trust in the convenient, secure, and internationally aligned exchange of data. Structure of the Consultation Process According to the PDPC, the initiative to develop the draft PDPA guidelines is being implemented through three core phases: Review of international best practices. The PDPC has conducted a comparative review of data protection guidance and regulatory approaches in jurisdictions with internationally recognized standards, including Singapore, the United Kingdom, the European Union (EU), and Japan. These materials are intended to serve as a reference point for developing practical recommendations across key subject areas under the PDPA. Identification of practical issues and challenges. To ensure that the guidelines respond to real‑world compliance challenges in Thailand, the PDPC has gathered views from a broad range of stakeholders across the public sector, the private sector, and the general public. This phase included focus group discussions and questionnaires aimed at identifying areas to provide organizations with greater clarity and consistency on regulatory expectations. Preparation of draft guidelines. Insights from the comparative study and stakeholder
