The framework
Taiwan regulates personal data through the Personal Data Protection Act (PDPA), dating from 2010 and supervised by the Personal Data Protection Commission.
For advertisers the consent posture matters most, and Taiwan sits in the opt-in bloc, where tracking and outreach need permission up front.
Key instruments
Personal Data Protection Act (PDPA)
Taiwan's PDPA dates to 2010 (roots in 1995) and is mid-transformation. 2023 amendments raised penalties and mandated an independent Personal Data Protection Commission, and a further amendment promulgated in November 2025 makes the Commission the sole supervisory authority once a start date is set. Until then the preparatory office works alongside ministry-by-ministry enforcement.
Marketing and advertising
Consent or a listed statutory basis; notification duties at collection; opt-out must be honored for marketing, and first-use marketing requires a free opt-out channel. Most channel decisions here follow from that consent rule.
Cross-border transfers
Permitted unless restricted by ministries (restrictions exist for some destinations); sectoral rules add localization pockets.
Enforcement and penalties
2023 amendments raised fines (to NTD 15M for serious security failures) after the iRent breach; criminal exposure for unlawful use.
