Overview
Thailand will implement a new requirement for Thailand Board of Investment (BOI) user registration under the Personal Data Protection Act (PDPA), effective September 1, 2025. The rule applies to all users of the BOI Single Window System, the online platform used for company applications and compliance with the Thailand Board of Investment.
Companies must appoint at least one BOI Account Manager to manage and oversee user access. The Account Manager may be an authorized company director or an appointed employee, and multiple Managers can be designated. Once approved, Managers will be able to invite up to 20 additional users per account using a time-sensitive QR code.
To complete registration, companies must upload several documents through the BOI system, which include the following:
- A signed Power of Attorney (POA) from the company’s directors, appointing the Manager. The POA must include a 10-baht stamp duty.
- A signed copy of the director’s Thai ID or passport (for foreign nationals).
- A signed copy of the Manager’s Thai ID.
- An employee card or HR-issued verification letter confirming the Manager’s employment status.
This requirement is designed to ensure compliance with Thailand’s PDPA framework and strengthen the security of BOI digital services. Companies are advised to complete registration early to avoid disruptions in system access as the September 2025 deadline approaches.

Looking Ahead
Employers and companies using the BOI Single Window should prepare for registration by gathering the required documentation and appointing an Account Manager. Proactive compliance will ensure uninterrupted access to the BOI system and reduce operational risks. Additional guidance from Thai authorities may follow as the PDPA continues to shape corporate data and access protocols.
