Thailand’s Personal Data Protection Committee (PDPC) has launched a public consultation period on a draft notification setting out criteria for data subject access requests (DSARs). The draft notification addresses practical uncertainties in handling DSARs by introducing standardized procedural requirements for data controllers. The consultation period runs from April 16 to May 15, 2026. The notification will enter into force 30 days from the date of its publication in the Government Gazette.

Information required under section 23 of the PDPA and information that must be recorded pursuant to section 39 of the PDPA—such as the categories of personal data collected and purposes of processing—must also be made available.
Submission channels and formal requirements. Data controllers must provide at least in-person and postal channels for DSARs, while electronic or other channels are optional. Requests may be made either directly by the data subject or through an authorized representative, and must be signed and include sufficient identifying information, a preferred response method, and DSAR details. Identity verification documents (and proof of authority if the request is through a representative) are required, and additional documentation may be requested for verification or communication purposes. Data controllers may use different verification methods for DSARs submitted via electronic or other channels, provided this does not create undue obstacles to the exercise of data subject rights.
Verification and response timelines. Data controllers must complete preliminary verification within seven business days of receiving a request. If a request is incomplete or inaccurate,
