Thailand Issues New Regulation on Personal Data Protection for Telecom Users

Subscribe to Updates

Thailand’s National Broadcasting and Telecommunications Commission (NBTC) has issued the Notification of the NBTC Re: Measures to Protect Telecommunications Service Users’ Rights Regarding Personal Data, Privacy Rights, and Freedom of Telecommunications to replace the previous 2006 notification of the same name. The replacement notification supports compliance with the Personal Data Protection Act B.E. 2562 (2019) (PDPA), modernizes the regulations in response to technological change and the convergence of digital business, and enhances the protection of telecommunications users’ personal data, privacy rights, and freedoms.

Key aspects of the replacement notification are highlighted below.

User Data and Consent

The notification specifies that “user’s personal data” includes name, address, ID number, mobile number, usage information, and user behavior that can identify the user. “User” does not include resellers of telecommunications services.

To collect, use, or disclose users’ personal data for a purpose other than telecommunications service, service providers must obtain each user’s consent prior to or at the time of collecting the data. The consent (whether written or electronic) must be separate from the telecommunications service agreement. Service providers must clarify the purpose of collecting data, and they must honor users’ rights to opt in and opt out by providing clear and convenient channels for users to withdraw any of their information or cancel any services offered by the operator.

Service providers must add an electronic channel for receiving requests from users to review, access, edit, change, or obtain a copy of their data. The electronic channel must also allow requests from users to suspend use or disclosure of their personal data and withdraw consent to collect, use, or disclose their personal data. In addition, service providers must have a system for verifying the identity of users who want to exercise the rights listed in this paragraph.

Data Collection and Storage

Collection of a user’s personal data is limited to necessary and lawful purposes. Service providers must also provide the user with a channel to update their personal data. While under contract to provide a user with telecommunications service, the service provider must keep the user’s personal data for 90 days. If the user makes any complaint regarding the service, the service provider must keep the relevant user’s data until the complaint is resolved, but not exceeding two years.

Collection of sensitive personal data (e.g., data on race or religion, criminal record, health data, disability data, biometric data) is prohibited without explicit consent from the user, unless it is to provide telecommunications service to benefit a disabled person.

Data Security and Device Access

Service providers must have security measures for the unauthorized or unlawful loss, accessing, use, alteration, correction, or disclosure of users’ personal data. These measures must be reviewed when necessary or when technology has changed. Service providers must notify the NBTC within 72 hours of becoming aware of a breach of any user’s personal data and within 24 hours if the breach is likely to result in a high risk to the rights and freedoms of the affected user.

Policy Formulation

Telecommunications operators are encouraged to establish a policy aligned with the NBTC notification and the PDPA. The policy should be transparent and available in Thai and other relevant languages, and it must be presented to the NBTC for approval.

Thailand’s Personal Data Protection Act B.E. 2562 (2019) (PDPA) could soon see some important changes, as a draft bill to amend the PDPA has been introduced in the House of Representatives. The draft amendment is currently in the public consultation phase, with comments accepted from July 16 to August 15, 2026. If enacted in its current form, the amendment would make three key changes: expanding the government exemption to cover anticorruption operations, introducing a statutory definition of “government agency,” and restructuring the lawful bases for personal data processing to align with international standards. Background The PDPA has encountered several enforcement challenges since its implementation, including three core problems identified by the bill’s sponsors: (1) the current exemptions for government agencies do not cover anticorruption and misconduct-prevention operations; (2) the PDPA lacks a clear statutory definition of “government agency,” causing legal uncertainty as to which entities are covered; and (3) the existing framework for lawful bases of data processing does not align with international standards—particularly the multiple-lawful-bases system in the EU’s General Data Protection Regulation (GDPR)—making compliance inflexible for both government and private sector entities. Expanded Government Exemption The current PDPA exempts government agencies performing duties related to national security (including fiscal security), public safety, anti-money laundering, forensic science, and cybersecurity. The proposed amendment adds “prevention and suppression of corruption and misconduct” to this list of exempted functions. This would allow anticorruption bodies—most notably the National Anti-Corruption Commission (NACC), which is identified as a directly affected party—to collect, use, and disclose personal data without being subject to PDPA requirements when carrying out their duties. New Statutory Definition of “Government Agency” Notably, while the current PDPA use the term “government agency” in several provisions, the term is not comprehensively defined, creating potential uncertainty as to its scope. The draft bill therefore

On July 23, 2026, the Bank of Thailand (BOT) released for public comment its draft Notification on Digital Channel Security, which would significantly expand the scope and stringency of Thailand’s existing mobile banking security framework. If finalized in its current form, the draft notification would extend mandatory security requirements to credit card providers and credit providers, cover internet banking in addition to mobile applications, phase out SMS one-time passwords (OTPs) for transaction authentication, and introduce biometric verification requirements for high-value transactions. The public comment period is open through August 24, 2026. Background The BOT’s existing Mobile Banking Security Notification, issued in 2024, sets minimum security standards for financial institutions, specialized financial institutions (SFIs), and e-money providers, significantly reducing “money-draining app” fraud. However, fraudsters have since shifted to nonbank providers and internet banking channels, prompting the BOT to propose broader security requirements. Expanded Scope of Regulated Entities and Channels The existing Mobile Banking Security Notification covers only financial institutions, SFIs, and e-money providers offering mobile banking services. The draft expands coverage in two key areas: entities and channels. On the entity side, it adds credit card providers and credit providers that offer fund transfers to third parties at other financial service providers or that provide cash withdrawal services to individual retail customers. On the channel side, it broadens coverage to include internet banking in addition to mobile banking. Strengthened Customer Authentication The draft introduces enhanced authentication requirements in three areas: Service enrollment and device changes. Providers must implement rigorous identity verification, notify customers of enrollment results through out-of-band communication channels, and adopt risk-mitigation measures such as cooling-off periods and temporary transaction limits. Transaction-level authentication. Providers must use two-factor authentication for fund transfers, cardless ATM withdrawals, and transaction limit increases. Secure authentication factors. Key requirements include the following: “What-you-know” factors must

Data protection officers (DPOs) have become a fixture of Thailand’s privacy compliance landscape since the Personal Data Protection Act B.E. 2562 (2019) (PDPA) took full effect and the Office of the Personal Data Protection Committee (PDPC) began requiring certain organizations to appoint them. On July 7, 2026, the Office of the PDPC presented draft guidance on DPOs as part of a public consultation on a series of draft personal data protection manuals and recommendations. The draft offers the clearest indication yet of how the regulator expects the DPO role to work in practice, addressing recurring implementation issues under the PDPA—including when an organization must appoint a DPO, how the DPO should operate independently, how to manage conflicts of interest, and how data subjects and regulators should be able to contact the DPO. Because it remains in draft, organizations have an opportunity to weigh the practical implications now before the guidance is finalized. When a DPO Must Be Appointed The draft guidance clarifies the triggers for mandatory DPO appointment, including: Regular and systematic monitoring of personal data or systems on a large scale, such as tracking, analyzing, or predicting behavior, attitudes, or individual characteristics. Core activities involving large-scale processing of sensitive personal data, such as health data, biometric data, or criminal records. Certain foreign-organization representative arrangements. Public-sector coverage under relevant notifications identifying government entities that must appoint a DPO. Processing involving 100,000 or more data subjects may be considered large-scale. The guidance also contemplates voluntary DPO appointment for organizations that wish to raise their privacy governance standards, and such organizations should still comply with the standards applicable to DPOs under the law. Independence and Reporting Lines The draft guidance identifies lack of DPO independence as a core risk because an ineffective or constrained DPO may be unable to raise deficiencies

Vietnam’s new E-Commerce Law, which took effect on 1 July 2026 along with its implementing Decree No. 248/2026/ND-CP (Decree 248), marks a significant development in the country’s approach to online intellectual property (IP) enforcement, reflecting a clear shift from a reactive model of intermediary liability to one that expects platforms to play a more active role in preventing infringement. From notice-and-takedown to platform responsibility The most significant change introduced by the E-Commerce Law is the transformation of the legal role of e-commerce platforms. The existing safe harbor provisions under the IP Law and the copyright notice-and-takedown regime established by Decree 17/2023/ND-CP (Decree 17) largely required intermediaries to act only after receiving notice of infringement. Once infringing content had been removed, the platform’s legal obligation was generally considered fulfilled. The new legislation adopts a fundamentally different approach. Article 17 of the E-Commerce Law requires intermediary platforms to screen information relating to goods and services before publication in order to prevent listings involving counterfeit or IP-infringing goods, and goods of unknown origin. Rather than relying exclusively on complaints from rights holders, platforms are now expected to implement preventive measures before infringing listings become publicly available. Decree 248 further requires platforms to update keyword filters based on recommendations issued by competent authorities. These filtering mechanisms are intended to prevent prohibited listings from appearing on the platform and represent a further move away from a purely complaint-driven enforcement model. The legislation also introduces Vietnam’s first statutory stay-down obligation. Under the E-Commerce Law and Decree 248, major digital platforms must maintain automated systems capable of reviewing, warning against, and removing unlawful listings while also implementing measures to prevent repeat violations, defined under Decree 248 as conduct that has previously been identified and handled by the platform, but continues to recur. This obligation addresses one
