Thailand’s Personal Data Protection Act: A Guide to the Partial Compliance Extension

In May 2020, the Thai Cabinet approved a royal decree granting a one-year exemption from certain provisions of the Personal Data Protection Act 2019 (PDPA), which had been scheduled to take full effect on May 27, 2020. The new decree has extended the effective date for a number of the law’s provisions to May 31, 2021.

Key Elements of the Extension

Under the decree, certain critical provisions of the PDPA are not enforceable against exempted businesses (see list below) during the extension period, including the following:

  • General requirements and obligations on data controllers. Specifically, the postponed enforcement covers consent requirements, notification requirements, establishment of lawful basis, requirements on the collection of personal data from other sources, and processing of minors’ personal data. The enforcement of a second list of requirements is also postponed, including observance of data subjects’ rights and data erasure or destruction requirements, the implementation of appropriate internal security measures to prevent unauthorized access (section 37 (1)), provision of data breach notifications, appointment of data protection officers (DPOs), filing complaints, and penalties.
  • The grandfather provision (section 95) is also within the scope of the extension. This means that personal data collected or processed during the extension period will not be subject to the requirements enumerated in the second list above when they come into force in 2021. Furthermore, this data can be retained and used after the extension period has lapsed, provided that doing so is within the original purposes stated for collecting and processing the personal data. It is especially important to note that the scope of the grandfather provision does not include disclosure of personal data or processing of personal data outside of the original purposes stated.

However, as required by section 4, data controllers must still implement a minimum level of security protection measures for personal data in accordance with the standards to be prescribed by the Ministry of Digital Economy and Society, expected later this year.

It should also be noted that the requirement for the regulator to issue supplemental notifications and regulations is not within the scope of the extension. The Personal Data Protection Commission (PDPC) is therefore expected to continue issuing these supplemental measures during the extension period.

Exempted Businesses

The list of exempted businesses, below, covers a wide range of sectors and industries, and applies regardless of location:

  • Agriculture
  • Industrial businesses
  • Commerce
  • Medical and public health businesses
  • Energy, steam, water, waste disposal, and related businesses
  • Construction
  • Repair and maintenance
  • Transportation, logistics, and warehousing
  • Tourism
  • Communication, telecommunications, computers, and digital enterprises
  • Financial, banking, and insurance enterprises
  • Real estate
  • Professional practice
  • Administration and support
  • Science and technology, academia, social welfare, and arts
  • Education
  • Entertainment and recreation
  • Security
  • Household operations and SMEs that cannot be classified
  • Government agencies
  • Foreign government agencies and international organizations
  • Foundations, associations, and religious and nonprofit organizations

What to Do Now

In addition to staying up to date on the issuance and implementation of supplemental notifications and regulations under the PDPA over the coming year, businesses should make use of the additional time to prepare for compliance. A sample framework for doing so is provided below.

Step 1: Identify the personal data currently possessed by the company

Estimated timeframe: 1–3 months

In this stage, it is important to understand the PDPA’s requirements and conduct self-assessments to identify an entity’s current and anticipated personal data processing activities. To identify the main processing activities, companies should answer the five Ws:

  • Who are the relevant data subjects and the responsible personnel?
  • What types of personal data are collected and processed, and what are the sources?
  • When is the personal data collected and updated, and how long is it retained?
  • Where is the physical and digital data stored and transferred to (i.e. within Thailand or overseas)?
  • Why is the personal data being collected or processed?

This should be a reported in an internal assessment to aid widespread understanding of the practice—especially the original purpose for collecting or processing the personal data—within the organization.

Gaps and mitigation measures should also be identified, including:

  • processing activities that require consent as the lawful basis;
  • processing activities that can rely on another lawful basis (e.g. “legitimate interest”);
  • relevant retention periods pertaining to the various types of personal data; and
  • list of data processors, the scope of their data processing activities, and relevant personal data pertaining to the activities.

Step 2: Close the gaps and monitoring for new subordinate regulations

Estimated Timeframe: 2-4 months for closing gaps, monitoring ongoing until May 31, 2021

In this stage, organizations should monitor the issuance and development of new subordinate legislation—including through public hearings—to ensure that they are aware of their compliance obligations. At the same time, it will be necessary to focus also on closing the gaps identified in Step 1 by implementing the necessary mitigation measures and putting measures in place to ensure operational compliance. This may include preparing the following:

Privacy policies for relevant data subjects. Where consent is identified as the lawful basis, consent forms must be prepared for the relevant data subjects (e.g. individual customers, employees, etc.).

  • A data processing agreement (or addendum) template to be arranged, proposed, and countersigned by the relevant data processors.
  • A record of processing activities.
  • A record of internal assessments where legitimate interest is to be relied upon as the lawful basis (noting that these should be carried out in consideration of organizational conflicts of interest).
  • Plans for a DPO or DPO team, depending on the size of the operation and quantity of personal data involved, and in accordance with the DPO qualifications prescribed by the PDPC.
  • A custom internal training program, addressing current gaps and relevant parties in the context of the new legal requirements.
  • Internal rules forbidding collection of personal data without justification or lawful basis, or that is not necessary for business operations. Any personal data of this type that is currently being processed should also be deleted at this time.

When the subordinate laws on data subject rights become publicly available, it will be necessary to examine the requirements and set up a process for managing requests to uphold data subject rights, as well as data controller and processor obligations under the PDPA.

Achieving Compliance on Schedule

By following these steps, organizations can ensure that they will be fully compliant when the extension period ends on May 31, 2021. The estimated timeframes of the various steps listed above can give an idea of how long each step will take, but the actual schedules should be determined based on the level of PDPA readiness within the organization, the scale of implementation, and any future developments of the subordinate legislation under the PDPA. Companies should work closely with local legal counsel to ensure that their compliance measures are on track, and will be effective when the law comes into force.

Tilleke & Gibbins will continue to monitor the development of the PDPA and provide updates as they emerge. If you have questions about the PDPA, or any other aspect of data compliance in Thailand, please do not hesitate to contact any member of the PDPA team, including Athistha (Nop) Chitranukroh at [email protected] or Nopparat Lalitkomon at [email protected].

On September 10, 2025, Vietnam’s National Credit Information Center (CIC) reported to the Vietnam Cybersecurity Emergency Response Team (VNCERT) a suspected significant cybersecurity incident involving unauthorized access to the CIC’s credit information database. A hacker group has claimed responsibility and allegedly posted over 160 million records for sale, including sensitive personal and financial data. Implications for Banks and Financial Institutions Companies that share customers’ or potential customers’ personal data with the CIC for credit scoring or other purposes—and continue to act as a data controller for such data—may be obligated under Vietnam’s Personal Data Protection Decree (PDPD) and related regulations to: Notify A05 (Department of Cybersecurity and High-Tech Crime Prevention) and the State Bank of Vietnam without delay. Inform affected individuals if their personal data is at risk. Recommended Actions Companies that could be impacted by this data breach should take the following actions: Conduct an internal review of CIC-related data in their systems, and identify whether and how the systems have been affected by this incident. Assess whether to notify regulators and customers/potential customers. Enhance cybersecurity controls, monitor for suspicious activity, and implement additional safeguards to prevent secondary breaches.

Thailand’s Securities and Exchange Commission (SEC) has amended its digital asset regulations to permit the offering, trading, and provision of services related to tokenized environmental commodities by licensed digital asset exchanges, brokers, and dealers. This regulatory development is aimed at facilitating Thailand’s green economy and net-zero goals while diversifying the products available in the regulated digital assets market. The environmental commodities currently being traded on certain market platforms and via over-the-counter channels include: Carbon credits: Tradable certificates representing a reduction of CO₂ emitted into the atmosphere. Renewable energy certificates (RECs): Tradable proof of electricity generated from renewable energy sources. Carbon allowances: Tradable permits to emit a capped amount of greenhouse gases. The tokenization of these instruments is essentially the process of converting them into digital tokens, making it possible to list them on blockchain exchanges for trading purposes. Background Tokenized carbon credits, RECs, and carbon allowances fall under the category of utility tokens for consumption purposes or tokens representing entitlement certificates—that is, group 1 utility tokens, which are not considered financial products. The offering, trading, and provision of secondary-market services of this type of token are exempted from licensing requirements for regulated digital asset businesses under the Emergency Decree on Digital Asset Businesses B.E. 2561 (2018). Under the previous regulatory framework, licensed digital asset business operators were not allowed to provide services involving such unregulated tokens, as it was deemed to be engaging in “other businesses,” which digital asset operators generally cannot engage in without prior SEC approval. Regulatory Amendment Under the amended digital asset regulations, licensed digital asset exchanges, brokers, and dealers may now apply for SEC approval to offer services related to these tokenized assets as “other businesses,” including listing them for trading on digital asset exchanges. Apart from requiring operators to comply with the general conditions

With advancements in health technology, telemedicine has taken on a wider online presence in Thailand. Under the Medical Facility Act, licensed clinics and hospitals may now diagnose, prescribe, and issue electronic prescriptions during a video call, provided they maintain patient confidentiality and proper recordkeeping. As a complementary concept, a telepharmacy allows a pharmacist to verify prescriptions, counsel patients, and dispense medication from a remote site. Hospitals, clinic chains, and some retail pharmacy groups have adopted “drive-thru” or “locker” pick-up points where drugs are bagged only after a real-time video consultation with a registered pharmacist. The clear benefits of telehealth include shorter waiting times and broader access to specialists, which is in the public interest. Drug Distribution and Advertising in Thailand The online pharmacy ecosystem creates a legal bridge in that once a teleconsulting doctor issues an e-prescription, a licensed pharmacy can lawfully dispense and deliver the medicine prescribed to the patient’s door. Nonetheless, the critical compliance component remains the advertising of medicinal drugs. It is still not allowed to advertise prescription/pharmacy-dispensed drugs to the public in Thailand. Although Thailand’s Drug Act of 1967 was written more than half a century ago, it still governs the trading of every medicinal drug that makes its way to consumers in Thailand—whether bought at a pharmacy or delivered with a few taps on a smartphone. First and foremost, the pharmacy must hold a license to sell medicinal drugs as a retailer. It is also mandatory that arrangements be made for a pharmacist to be on duty during opening hours. Drugs are classified into three main categories: prescription drugs, pharmacy-dispensed drugs, and over-the-counter (OTC) drugs. The listing of OTC drugs with their prices via an online platform is allowed, as only OTC drugs may be advertised directly to the public. However, naming or showing

Thailand’s National Space Policy Committee (NSPC) has proposed new regulations that would permit foreign satellite operators to provide services within the country. The draft announcement responds to rapid advancements in digital and space technologies that have led to new global satellite operators expanding their services worldwide, including into Thailand. These include low-Earth-orbit (LEO) satellite constellations offering high-speed internet, nonterrestrial network (NTN) technologies that integrate terrestrial and satellite communications, and direct-to-device (D2D) technologies that transmit signals directly from satellites to mobile devices without relying on terrestrial networks. The draft aims to replace the existing announcement, which was issued in 2021, to better align with current national policies on foreign satellite usage. The draft announcement was published for public consultation on August 20, 2025, with the comment period concluding on September 3, 2025. Applying for Authorization Two types of operators may apply for authorization: Thai operators who intend to use foreign satellites owned by World Trade Organization (WTO) member countries to provide satellite communication services to third parties; and Foreign operators of satellites owned by WTO member countries who intend to operate a business providing satellite communication services within Thailand. Applications for approval must be submitted to the National Broadcasting and Telecommunications Commission (NBTC) according to the NBTC’s established procedures. In considering whether to permit foreign satellites to provide services within Thailand, the relevant authority will take into account technical justifications, economic benefits, social benefits, and national security considerations. Determining Satellite Ownership The determination of which country qualifies as the owner of a satellite is based primarily on the country that holds the satellite network filing rights registered with the International Telecommunication Union (ITU). The satellite network filing includes details regarding frequency usage, orbital positions, and technical specifications of the satellite operations. It serves as a regulatory tool used by the
