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.

On June 18, 2026, Thailand’s Office of the Personal Data Protection Committee (PDPC) published two notifications in the Government Gazette establishing Thailand’s first formal certification framework for personal data protection standards under the Personal Data Protection Act B.E. 2562 (2019) (PDPA). The notifications, which took immediate effect, introduce a voluntary certification framework aimed at promoting accountability, strengthening organizational data protection governance, and aligning Thailand more closely with international frameworks that recognize certification as a key compliance tool. Certification Criteria The first notification sets out the assessment criteria for organizations seeking certification. Applicants must undergo an evaluation against a framework comprising four assessment categories, 10 focus areas, and 128 assessment criteria covering key elements of a privacy management program. These include: Organizational oversight and internal policies and procedures. Human resource development, including staff training and awareness programs. Clearly defined operational processes and procedures covering data subject rights, transparency obligations, records of processing activities, and lawful basis management, as well as contractual safeguards such as data-processing and data-sharing agreements and risk assessments, including Data Protection Impact Assessments. Technical measures encompassing data security controls and breach response capabilities Based on the assessment results, organizations may be awarded either a PDPA Compliance Certificate or a higher-level PDPA Certificate accompanied by a certification mark. Application and Assessment Process The second notification establishes the application and assessment process for obtaining certification. Eligible applicants include government agencies and private-sector entities that demonstrate sufficient privacy governance maturity and meet the prescribed eligibility requirements. Applicants must submit their applications along with supporting documentation for review. Upon receiving an application, the Office of the PDPC will conduct a detailed evaluation, which may include both documentary review and on-site inspections. Incomplete applications may be rejected, though applicants are typically given a limited period to correct deficiencies before a final decision

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
