The Personal Data Protection Act B.E. 2562 (2019), known as the PDPA, came into full effect on June 1, 2022. Its purpose is to safeguard the rights of individuals in Thailand regarding their personal data.
With the PDPA, Thailand has aligned its data privacy standards closer to international frameworks such as the GDPR (General Data Protection Regulation of the European Union). This requires both government and private organizations to adjust and strengthen their data management practices

Legal Status of the PDPA
The PDPA is not merely a guideline or standard; it is an Act of Parliament, making it a national law. It applies to both individuals and organizations in Thailand, as well as to actions involving the personal data of people in Thailand.
Liabilities and Legal Penalties
As a law, the PDPA sets clear penalties for violations to ensure effective enforcement. These include:
a. Civil Liability
b. Criminal Liability
c. Administrative Penalties
Relationship with Other Laws
While the PDPA focuses on personal data protection, it interacts with other laws:
Electronic Transactions / Computer Crime Laws: The PDPA emphasizes protecting data and individual rights, while computer-related laws focus on punishing offenses against computer systems and stored data.
Industry-Specific Regulations: Some sectors, such as finance or healthcare, may have stricter data protection rules. Organizations must comply with the most stringent applicable laws.
In summary, the PDPA defines the legal boundaries and requirements for handling personal data in Thailand, ensuring both protection of individual rights and accountability of organizations.
The situations where the Personal Data Protection Act (PDPA) applies, or where a violation may occur, can be divided into four main categories:
1. Unlawful Collection of Personal Data
The PDPA applies when organizations collect personal data without a valid legal basis. Examples include:
2. Unlawful Use or Disclosure of Data
This occurs when organizations use collected data for purposes not consented to by the data subject. Examples include:
3. Data Breach and Security Failures
These occur when organizations fail to maintain adequate data security, resulting in damage, loss, or leakage of personal data. Examples include:
4. Ignoring Data Subject Rights
This occurs when organizations deny individuals rights without a valid legal reason. Examples include:
Section 19 Consent Principle
The core provision requiring that the collection, use, or disclosure of personal data must be based on the data subjects consent, unless another legal basis applies.
Section 23 Duty to Inform Purpose
Data controllers must clearly inform data subjects of the purpose and details of processing before or at the time of data collection.
Sections 3036 Data Subject Rights
These sections define the rights of data subjects, including:
Section 37 Duty to Ensure Security
Organizations are required to implement appropriate security measures to safeguard personal data.
Section 37 (4) Data Breach Notification
Data controllers must notify the PDPC (Personal Data Protection Committee) of a data breach within 72 hours after becoming aware of the incident.
Section 78 Criminal Penalties
Provides for imprisonment of up to 6 months or a fine of up to 500,000 THB, or both, for unlawful use or disclosure of personal data causing harm to the data subject.
Section 82 Administrative Penalties
Provides for an administrative fine of up to 5 million THB for violations of key obligations, such as failure to implement adequate security measures under Section 37.
