Thailand’s Public Consultation on Proposed PDPA Guidelines: Key Updates

Subscribe to Updates

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 Insights from the comparative study and stakeholder feedback are being consolidated to prepare draft guidance covering six core thematic areas (see the following section), intended to reflect both international standards and the practical realities of PDPA implementation in Thailand. The input gathered will be used to inform a draft set of guidelines.

Overview of Draft Guidelines

The consultation process has now advanced beyond open‑ended issue identification, with the PDPC presenting substantive draft guidelines that provide clearer insight into the regulatory focus of the six core thematic areas:

  • Lawful basis for processing personal data. The draft guidelines clarify the importance of lawful basis and lay out how organizations should identify, assess, and document lawful bases for the collection, use, and disclosure of personal data. They emphasize necessity, proportionality, and accountability and address both general and sensitive personal data, supported by practical examples, checklists, and FAQs.
  • Security measures and personal data breach notification. To address this area, the draft guidelines set out a structured framework for security measures, covering technical, administrative, and physical measures, as well as consideration for conducting data protection impact assessments (DPIAs) and managing risks arising from third parties and data transfers. They further provide detailed operational guidance on identifying and assessing personal data breaches, determining notification obligations, incident response procedures, documentation, and timelines for notifying the Office of the PDPC and affected data subjects.
  • Data protection officers (DPOs). The draft guidance clarifies when an organization is required to appoint a DPO and sets out expectations regarding the DPO’s role, professional qualifications, independence, reporting lines, and avoidance of conflicts of interest. It also includes checklists for key compliance concerns, such as the appointment process, the DPO’s position within the organization, and accessibility to data subjects and the Office of the PDPC.
  • Marketing and direct marketing. These guidelines also set out relevant data protection principles for the use of personal data for marketing and direct marketing purposes, such as purpose limitation, data minimization, lawful bases for processing, and applicable data subject rights. They categorize different types of marketing activities (including direct marketing, online tracking, profiling, and platform‑based targeting), provide practical organizational procedures on transparency, opt‑out mechanisms, and consent withdrawal, and provide illustrative case studies and FAQs on common marketing scenarios.
  • Records of processing activities (ROPAs). The draft ROPA guidelines position ROPAs as a core accountability and compliance tool, highlighting mandatory content, the roles of controllers and processors, and a structured approach to preparation, review, and updating ROPAs. This includes practical examples (e.g., HR, customer management, IT vendors, CCTV), templates, and a questionnaire for gathering information within the organization for filling in the ROPA.
  • Use of CCTV and access control systems. The guidelines address personal data processing involving CCTV and related surveillance technologies in housing estates and condominiums, with the objective of promoting PDPA‑compliant, industry‑consistent practices. Also covered are common risk areas, such as visitor management, biometrics, license plate recognition, and resident portals, as well as practical guidance and FAQs for typical operational scenarios.

Regulatory Signals

The April 1–2 public hearing indicates that the PDPC is moving into a more mature, internationally informed phase of PDPA guidance development while remaining attentive to domestic operational challenges. Although the forthcoming guidelines will not have the force of law, they are expected to influence regulatory expectations, compliance assessments, and enforcement decisions.

Organizations should therefore anticipate greater clarity but not a relaxation of PDPA obligations, and may wish to begin reviewing current compliance frameworks, particularly in higher‑risk processing areas, internal documentation practices, and governance arrangements, in preparation for the final guidance.

On May 26, 2026, Thailand’s Department of Land Transport (DLT) published for public consultation a draft amendment to the Ministerial Regulation on Electronic Ride-Hailing Vehicles that would, for the first time, allow juristic persons (legal entities) to register vehicles as electronic ride-hailing cars—a right that currently belongs exclusively to natural persons, limited to one person per one vehicle. If finalized in its current form, the regulation would significantly expand the supply side of Thailand’s ride-hailing market by enabling corporate fleet operators to enter the space. The public comment period is open through June 24, 2026. Key Principles Under the Draft Regulation Under the proposed amendment, juristic persons that maintain a fleet of at least 50 vehicles will be permitted to register vehicles as electronic ride-hailing cars. This represents a fundamental shift from the current framework, which restricts registration to individual natural persons on a one-person-one-car basis. Vehicle Specifications Corporate-owned ride-hailing vehicles must meet the following requirements: Be brand new from the factory, or no more than two years old from first registration with no more than 20,000 km of use. Not be a vehicle that has been reconstructed or repaired after involvement in a serious accident affecting safety—a standard consistent with public transport vehicles (RorYor. 6). Be classified as small, medium, or large in accordance with ministerial or director-general specifications. The vehicles may be equipped with safety devices such as interior or exterior cameras (video/photo recording) and can retain the original factory color of the vehicle body (no mandatory color change is required). License Plates Corporate ride-hailing vehicles will use license plates of the same size, characteristics, and color as those for private passenger vehicles not exceeding seven seats (RorYor. 1), rather than public transport plates. Potential Impact The government has stated that the regulation is intended to: Promote

On May 14, 2026, Thailand published a ministerial regulation in the Government Gazette to prescribe measures for prevention and suppression of technology crimes. The regulation creates a comprehensive procedural framework for returning money and digital assets to victims of technology crimes. It will take effect 90 days after publication (in mid-August 2026), giving affected entities a limited window to prepare. Mandatory Reporting Obligations for Financial Institutions When a deposit account, e-money account, or digital asset wallet is frozen in connection with a technology crime, the relevant financial institution or business operator must report transaction data to the Anti-Money Laundering Office (AMLO) via AMLO’s designated electronic system. Required data elements include account numbers (sender and receiver), names, identification or passport numbers, legal entity registration numbers, phone numbers, remaining balance, damage amount, transaction reference numbers, and the bank case ID. Institutions that already share data through the information-sharing system under the emergency decree are deemed to have satisfied this reporting obligation, creating an incentive for platform participation. When the Royal Thai Police or the Department of Special Investigation seize or freeze assets related to technology crimes, they must provide AMLO with investigation reports, complaint evidence, money-trail data, and account statements. Notification and Claims Process Once the AMLO secretary-general approves verified reports of a technology crime, the account information of persons connected to the crime will be published in the Government Gazette, triggering a 90-day window for victims to file claims and for related persons to file objections. Officers will also publish details on AMLO’s electronic media and send registered mail to identified victims, which will be deemed received after 7 days domestically or 15 days internationally. Victims have 90 days from the date the crime is published in the Government Gazette to file claims through AMLO’s electronic system. Claims must include

The surge in AI development has led to a desperate demand for large, high-quality training data. However, real-world data can be expensive to collect, difficult to access, and often subject to strict privacy and regulatory constraints. Synthetic data, which consists of artificially generated records that replicate the statistical properties of real-world data without reproducing specific individuals’ information, provides an appealing solution by generating artificial datasets at scale without relying on identifiable personal information. It combines speed, cost efficiency, and regulatory compliance, making it a sensible alternative for organizations seeking to reduce risks while maintaining data utility. When properly anonymized, synthetic datasets may fall outside the scope of laws such as the EU’s General Data Protection Regulation (GDPR) or Thailand’s Personal Data Protection Act (PDPA), reducing compliance burdens while still supporting high-quality model training. However, relying on synthetic data without rigorous legal due diligence could be a strategic mistake. It replaces one set of known risks (scraping, direct privacy liability) with a new set of complex liabilities. The narrative that synthetic data is a “silver bullet” for privacy and IP compliance is dangerous and could be misleading. While synthetic data addresses data scarcity, it also introduces new legal uncertainties. Legal counsel should anticipate downstream risks arising from compromised data sources. Models trained on unlawfully obtained data may need to be decommissioned, even if their outputs appear lawful. What is synthetic data? Synthetic data refers to artificially generated information created using AI techniques such as deep learning and generative models. Instead of copying real records, it reproduces the statistical patterns and relationships found in the original dataset. Synthetic data generally falls into three categories: Fully synthetic data – Entirely new data points generated from learned patterns. The model studies the structure of the original data and produces records that resemble real-world

Thailand’s Electronic Transactions Development Agency (ETDA) has released a revised draft Electronic Transactions Act (ETA) for public hearing from May 12, 2026, to June 15, 2026. This is not merely an amendment to certain provisions of the current ETA, but a comprehensive redrafting of the entire act. The revised draft ETA introduces several significant changes from the current framework, with practical implications for businesses operating in Thailand. Unified Coverage of Public and Private Sectors The current law segregates government transactions into a separate chapter with distinct rules. The draft ETA eliminates this division, defining “transaction” to encompass civil and commercial juristic acts as well as administrative procedures, administrative contracts, and other acts of government agencies. Enhanced E-Signature Definition The definition of “electronic signature” is broadened to expressly include biometric data and refocused on identifying the signatory and demonstrating intent regarding the content of the electronic data. Shift in Burden of Proof When a party challenges the reliability of electronic data created using a “trusted electronic method” or a method prescribed by the ETDA, the burden of proof and the cost of proving unreliability shifts to the challenger. Introduction of New Digital Method Concepts The draft ETA introduces several new digital method concepts that are not currently recognized under the existing ETA framework. These include: Electronic timestamping (e-timestamp) Electronic registered delivery Electronic company seals Electronic stamp duty compliance Electronic identity authentication and verification Electronic transferable records (electronic bills of lading, promissory notes, and similar negotiable instruments) Recognition of Automated Systems and Electronic Contracting The draft ETA expressly recognizes the legal validity and enforceability of contracts formed through automated systems, including contracts concluded entirely between automated systems or between an automated system and a person. A party may not deny the binding effect of such contracts solely because no human review
