1. What is PDPA? (Thailand's Personal Data Protection Act B.E. 2562)

The Personal Data Protection Act B.E. 2562 (2019), commonly known as PDPA, is Thailand's first comprehensive data protection legislation. Often compared to the European Union's General Data Protection Regulation (GDPR), the PDPA establishes a legal framework governing the collection, use, disclosure, and transfer of personal data by organizations operating in or targeting individuals within the Kingdom of Thailand.

The PDPA was enacted to address growing concerns about data privacy in Thailand's rapidly digitalizing economy. Before PDPA, data protection obligations were scattered across sector-specific regulations — including the Computer Crime Act B.E. 2550 (2007), the Credit Information Business Act, and various notifications from the National Broadcasting and Telecommunications Commission (NBTC). The PDPA consolidated and strengthened these protections into a single, unified law with extraterritorial reach.

Official Name: Personal Data Protection Act B.E. 2562 (2019)
Thai Name: พระราชบัญญัติคุ้มครองข้อมูลส่วนบุคคล พ.ศ. 2562
Administered by: Personal Data Protection Committee (PDPC) and Office of the Personal Data Protection Committee (OPDPC)
Scope: Any organization collecting, using, or disclosing personal data of individuals in Thailand

The PDPA defines "personal data" broadly as any information relating to a person that enables the identification of that person, whether directly or indirectly — but not including information of a deceased person. This includes names, identification numbers, addresses, phone numbers, email addresses, photographs, biometric data, IP addresses, cookie identifiers, location data, and any other information that can identify a natural person.

The law further recognizes a special category of "sensitive personal data" (Section 26), which includes data relating to racial or ethnic origin, political opinions, religious or philosophical beliefs, criminal records, trade union membership, genetic data, biometric data used for identification, health data, disability, sexual orientation, and any other data prescribed by the PDPC. Sensitive data is subject to heightened protection requirements and generally cannot be processed without explicit consent.

Key Roles Under PDPA

RolePDPA DefinitionExamples
Data SubjectA natural person whose personal data is collected, used, or disclosedCustomers, employees, website visitors, patients
Data ControllerA person or entity that determines the purposes and means of personal data processing (Section 6)Employers, hospitals, e-commerce platforms, banks
Data ProcessorA person or entity that processes personal data on behalf of and under the instructions of the data controller (Section 6)Cloud service providers, payroll vendors, marketing agencies
Data Protection Officer (DPO)A designated officer responsible for monitoring and advising on PDPA compliance (Section 41-42)Internal compliance officer, external DPO-as-a-service provider

2. When Did PDPA Come Into Effect?

The PDPA's path to full enforcement was marked by several postponements, largely due to the COVID-19 pandemic. Understanding this timeline is important for organizations assessing their compliance obligations and potential liability exposure.

DateEvent
May 27, 2019PDPA published in the Royal Gazette (enacted)
May 28, 2019Certain provisions take immediate effect (establishment of PDPC, appointment of Secretary-General)
May 27, 2020Original date for full enforcement of all provisions
May 2020First Royal Decree postpones full enforcement by 1 year due to COVID-19
May 2021Second Royal Decree postpones full enforcement by another year
June 1, 2022Full enforcement begins — all provisions of PDPA are in effect
2022-2023PDPC issues subordinate regulations, guidelines, and notifications clarifying compliance requirements
2024-2026PDPC continues issuing sector-specific guidelines and increasing enforcement activity; first enforcement actions reported

Important: Since June 1, 2022, all provisions of the PDPA are fully enforceable. Organizations that have not yet achieved compliance face potential administrative fines of up to 5 million THB per violation, criminal penalties, and civil liability for damages.

3. Who Must Comply with PDPA?

The PDPA has a broad scope of application. It applies to the collection, use, and disclosure of personal data by data controllers and data processors in the following circumstances:

Entities Subject to PDPA

Entity TypeExample Obligations
Private companies (Thai and foreign)Customer data privacy notices, employee data policies, vendor DPAs
SMEs and startupsSimplified but mandatory compliance — privacy notice, consent where required, data security
Multinational corporationsFull compliance plus cross-border data transfer mechanisms
E-commerce and digital platformsCookie consent, privacy policy, data subject rights portal
Healthcare providersHeightened obligations for sensitive health data, explicit consent
Financial institutionsAdditional sector-specific regulations alongside PDPA
Government agenciesSubject to PDPA with certain exemptions for national security and law enforcement
Non-profit organizationsSubject to PDPA when processing personal data of members, donors, or beneficiaries

Exemptions

The PDPA provides limited exemptions (Section 4), including:

It is critical to note that these exemptions are narrowly construed. Most organizations — regardless of size, industry, or nationality — must comply with PDPA if they process personal data of individuals in Thailand.

4. The 6 Lawful Bases for Data Processing

Under PDPA Section 24, a data controller may not collect personal data without the consent of the data subject, unless one of the other lawful bases applies. This "consent by default" framework is one of the key features of the PDPA that organizations must understand.

#Lawful BasisPDPA SectionDescriptionExamples
1 Consent Section 19 The data subject has given explicit consent to the processing. Consent must be freely given, specific, informed, and unambiguous. It must be clearly distinguishable from other matters and presented in an easily accessible and intelligible form using clear and plain language. Marketing emails, cookie tracking, sharing data with third-party partners
2 Contract Section 24(3) Processing is necessary for the performance of a contract to which the data subject is a party, or for taking steps at the request of the data subject prior to entering into a contract. Processing delivery address for an online purchase, salary payment for employees
3 Legal Obligation Section 24(6) Processing is necessary for compliance with a law to which the data controller is subject. Tax reporting, anti-money laundering requirements, labor law compliance
4 Vital Interest Section 24(2) Processing is necessary to prevent or suppress a danger to the life, body, or health of a person. Emergency medical treatment, disaster response
5 Public Interest / Official Authority Section 24(4) Processing is necessary for the performance of a task carried out in the public interest or in the exercise of official authority. Public health surveillance, national statistics, census data
6 Legitimate Interest Section 24(5) Processing is necessary for the legitimate interests of the data controller or a third party, unless overridden by the fundamental rights of the data subject. Requires a balancing test. Fraud prevention, network security, internal analytics, direct marketing to existing customers (with opt-out)

Note: Section 24(1) additionally permits collection without consent for historical documents or archives, research or statistics in the public interest, subject to the safeguards prescribed by the PDPC.

Practical Tip from Thundthornthep Yamoutai, Ph.D.: Many Thai organizations over-rely on consent as their sole lawful basis. This creates operational risk because consent can be withdrawn at any time (Section 19, paragraph 5). Where possible, identify and document an alternative lawful basis — particularly contract performance and legitimate interest — to build a more resilient data processing framework. A qualified PDPA advisory lawyer can help you conduct this analysis.

Special Rules for Sensitive Data

For sensitive personal data (Section 26), the PDPA imposes stricter requirements. Processing of sensitive data is generally prohibited unless:

5. 8 Data Subject Rights Under PDPA

The PDPA grants data subjects eight fundamental rights regarding their personal data. Organizations must establish internal processes to handle these rights requests and respond without undue delay — for access requests, within 30 days of receipt (Section 30, paragraph 4). The Act sets no fixed statutory period for the other rights, so 30 days is the recommended internal benchmark.

#RightPDPA SectionDescription
1 Right to Be Informed Section 23 Data subjects have the right to be informed about the collection and processing of their personal data before or at the time of collection. This is fulfilled through privacy notices.
2 Right of Access Section 30 Data subjects may request access to their personal data held by the data controller and obtain a copy of such data. The controller must respond within 30 days.
3 Right to Data Portability Section 31 Data subjects may request that the data controller transmit their personal data in a commonly used, machine-readable format to another data controller, where technically feasible.
4 Right to Object Section 32 Data subjects may object to the collection, use, or disclosure of their personal data, particularly when processing is based on legitimate interest or public interest.
5 Right to Erasure (Right to Be Forgotten) Section 33 Data subjects may request the deletion or destruction of their personal data when it is no longer necessary for the purpose for which it was collected, when consent is withdrawn, or when processing is unlawful.
6 Right to Restrict Processing Section 34 Data subjects may request that the data controller restrict the processing of their personal data in certain circumstances, such as when accuracy is contested or while an objection is being evaluated.
7 Right to Rectification Sections 35–36 Data subjects may request that inaccurate or incomplete personal data be corrected, updated, or supplemented. The controller must keep the data accurate, up to date and complete (Section 35); if it does not act on the request, it must record the request and its reasons in the records of processing (Section 36).
8 Right to Withdraw Consent Section 19, paragraph 5 Where processing is based on consent, data subjects may withdraw their consent at any time. Withdrawal must be as easy as giving consent. Withdrawal does not affect the lawfulness of processing conducted prior to the withdrawal.

Enforcement Note: Failure to respond to data subject rights requests within the statutory period (30 days for access requests under Section 30; without undue delay for other requests), or refusing requests without legitimate grounds, may result in complaints to the PDPC and subsequent administrative sanctions. Organizations should establish a documented intake and response process, ideally with a dedicated email address or web form for rights requests.

6. Key Compliance Requirements

Beyond understanding lawful bases and data subject rights, organizations must implement several operational compliance measures under the PDPA. This section covers the five most critical requirements that every data controller and data processor must address.

6.1 Privacy Notice (Section 23)

Data controllers must provide a privacy notice to data subjects before or at the time of data collection. The privacy notice must include:

6.2 Consent Management (Sections 19-20)

Where consent is the lawful basis for processing, the PDPA imposes specific requirements:

6.3 Data Processing Agreement (Section 40)

When a data controller engages a data processor (e.g., a cloud service provider, payroll vendor, or marketing platform), the controller must enter into a written Data Processing Agreement (DPA) (Section 40, paragraph 3) that specifies:

6.4 Data Protection Officer (Sections 41-42)

A Data Protection Officer (DPO) must be appointed in the following situations:

The DPO's responsibilities include:

The DPO can be an internal employee or an external service provider. The data controller must ensure the DPO has sufficient independence, resources, and access to carry out their functions without interference. The DPO's contact details must be published and communicated to the PDPC.

6.5 Data Breach Notification (Section 37(4))

72-Hour Rule: In the event of a personal data breach, the data controller must notify the PDPC within 72 hours of becoming aware of the breach, unless the breach is unlikely to result in a risk to the rights and freedoms of the data subject. If the breach is likely to result in high risk to the rights and freedoms of the data subject, the controller must also notify the affected data subjects without undue delay.

The breach notification to the PDPC must include:

7. Cross-Border Data Transfer Under PDPA

Sections 28 and 29 of the PDPA regulate the transfer of personal data to foreign countries. This is particularly relevant for multinational companies, organizations using cloud services hosted abroad, and businesses that share data with overseas partners.

General Rule

A data controller may transfer personal data to a foreign country only if the destination country has adequate data protection standards as prescribed by the PDPC. The criteria are set out in the PDPC Notification on the Protection of Personal Data Transferred Abroad under Section 28, B.E. 2566 (in force since 24 March 2024). As of the latest available information, the PDPC has not published a list of countries deemed to have adequate standards, so transfers in practice rely on the Section 29 safeguards: PDPC-certified Binding Corporate Rules (BCRs) or appropriate safeguards such as Standard Contractual Clauses (SCCs) under the Section 29 Notification B.E. 2566 [ต้องยืนยันสถานะล่าสุด].

Exceptions Allowing Cross-Border Transfer

Even without an adequacy determination, cross-border transfers are permitted in the following circumstances:

#ExceptionDescription
1Compliance with law (Section 28(1))The transfer is necessary to comply with a legal obligation
2Consent (Section 28(2))The data subject has been informed of the inadequate standards and has given consent
3Contract performance (Section 28(3))The transfer is necessary for the performance of a contract between the data subject and the data controller
4Pre-contractual measures (Section 28(3))The transfer is necessary at the data subject's request prior to entering into a contract
5Vital interests (Section 28(5))The transfer is necessary to protect the vital interests of the data subject or another person
6Important public interest (Section 28(6))The transfer is necessary for an important reason of public interest
7Contract for the benefit of the data subject (Section 28(4))The transfer is made under a contract between the data controller and another person or entity for the benefit of the data subject
8Binding Corporate Rules (BCRs) (Section 29, paragraph 1)Intra-group transfers under BCRs that provide appropriate safeguards, as approved by the PDPC
9Appropriate safeguards (Section 29, paragraph 3)Where no adequacy decision or certified BCR exists, the transfer may proceed if the controller or processor provides appropriate safeguards enforceable by data subjects, with effective legal remedies — e.g., Standard Contractual Clauses under the PDPC Notification under Section 29, B.E. 2566

Practical Guidance: Organizations using major cloud platforms (AWS, Google Cloud, Microsoft Azure) with servers located outside Thailand should conduct a transfer impact assessment and, where appropriate, implement Standard Contractual Clauses or BCRs under the PDPC Notification under Section 29, B.E. 2566. A PDPA lawyer can help structure these mechanisms to comply with Thai law while maintaining operational flexibility. For expert assistance, see our PDPA advisory services.

8. PDPA Penalties and Enforcement

The PDPA imposes three categories of penalties for non-compliance: administrative, criminal, and civil. These can be imposed concurrently, meaning an organization could face all three types of liability for a single violation.

8.1 Administrative Penalties (Sections 82–90)

ViolationMaximum Penalty
Breach of general controller obligations — Sections 21, 22, 24, 25, 27, 28, 32, 37 (including security measures and the 72-hour breach notification) — or obtaining consent by deception (Section 83; processor breaching Section 40: Section 86)Up to 3,000,000 THB per violation
Failure to appoint a DPO when required (Section 41; Section 82; processor: Section 85)Up to 1,000,000 THB
Failure to comply with an order or summons of the Expert Committee, or to cooperate with competent officials (Sections 75–76; Section 89)Up to 500,000 THB
Failure to provide a privacy notice (Section 23), to act on an access request within 30 days (Section 30, paragraph 4), or to keep records of processing activities (Section 39) (Section 82)Up to 1,000,000 THB
Non-compliance with cross-border transfer rules (Sections 28–29): general data (Section 83) / sensitive data (Section 84) (processor: Sections 86 / 87)Up to 3,000,000 THB (general data) / 5,000,000 THB (sensitive data)

8.2 Criminal Penalties

OffenseImprisonmentFine
Unlawful use, disclosure or cross-border transfer of sensitive personal data (Section 26) in breach of Section 27 or 28, in a manner likely to cause damage, loss of reputation, contempt, hatred or embarrassment (Section 79, paragraph 1)Up to 6 monthsUp to 500,000 THB
The same conduct committed for unlawful gain (Section 79, paragraph 2); the offense is compoundable (Section 79, paragraph 3)Up to 1 yearUp to 1,000,000 THB
Unauthorized disclosure of personal data obtained in the performance of duties under PDPAUp to 6 monthsUp to 500,000 THB

Director and Officer Liability (Section 81): If a legal entity commits an offense under the PDPA, and the offense was committed by the order or act of a director, manager, or person responsible for the operations of that legal entity, or where such a person had a duty to give orders or act and failed to do so, resulting in the offense, such person shall also be liable to the same criminal penalty as the legal entity. This personal liability provision makes PDPA compliance a board-level concern.

8.3 Civil Liability

Under Sections 77-78 of the PDPA:

11. Frequently Asked Questions

Q: What is PDPA and when did it come into full effect in Thailand?

PDPA stands for the Personal Data Protection Act B.E. 2562 (2019), Thailand's comprehensive data protection law. It was enacted in May 2019 and came into full enforcement on June 1, 2022, after multiple postponements due to the COVID-19 pandemic. The law is administered by the Personal Data Protection Committee (PDPC) and the Office of the Personal Data Protection Committee (OPDPC). It applies to any organization that collects, uses, or discloses personal data of individuals in Thailand, regardless of whether the organization is based in the country.

Q: What are the penalties for PDPA non-compliance in Thailand?

PDPA imposes three types of penalties: (1) Administrative fines of up to 5 million THB per violation, issued by the Expert Committee (Section 90); (2) Criminal penalties including imprisonment of up to 1 year and/or fines of up to 1 million THB for certain offenses such as unauthorized use of sensitive data (Section 79); and (3) Civil liability including actual damages, with punitive damages of up to twice the actual damages awarded by the court (Sections 77-78). Directors and officers can be held personally liable under Section 81 if the offense resulted from their order or act, or from their failure to act where they had a duty to do so.

Q: Do I need a Data Protection Officer (DPO) under Thailand's PDPA?

Under Section 41 of the PDPA, a DPO must be appointed when: (1) the data controller or processor is a public authority; (2) the organization's processing requires regular monitoring of personal data or systems because of the large volume of personal data prescribed by the PDPC (Notification under Section 41(2), B.E. 2566); or (3) the organization's core activities involve processing of sensitive personal data under Section 26. The DPO can be an employee or an external service provider, and their contact details must be published and communicated to the PDPC. Even when not legally required, appointing a DPO is considered best practice.

Q: Can personal data be transferred outside Thailand under PDPA?

Yes, but cross-border data transfers are restricted under PDPA Sections 28-29. The receiving country must have adequate data protection standards as determined by the PDPC, or the transfer must fall under specific exceptions: compliance with law, consent of the data subject (after being informed of inadequate standards), performance of a contract, vital interests, important public interest, or a contract with a third party for the benefit of the data subject. Organizations can also rely on PDPC-certified Binding Corporate Rules (BCRs) or appropriate safeguards such as Standard Contractual Clauses under the PDPC's Section 29 Notification (B.E. 2566).

Q: How can a PDPA lawyer help my business achieve compliance in Thailand?

A specialized PDPA lawyer helps businesses achieve compliance through: data mapping and gap analysis; drafting compliant privacy notices, consent forms, and data processing agreements; advising on lawful bases; establishing breach notification procedures (72-hour rule); setting up data subject rights request workflows; advising on cross-border transfer mechanisms; conducting DPIAs; training staff; and acting as or supporting the DPO.
