What is the Thailand Digital Arrival Card?
The Thailand Digital Arrival Card (TDAC) is a mandatory electronic form that all foreign nationals must complete before entering Thailand. This digital system replaces the traditional paper TM6 form and has been implemented starting May 1, 2025.
The TDAC aims to streamline the immigration process by allowing travelers to submit their information online within 72 hours prior to arrival. This digital approach enhances efficiency at immigration checkpoints and improves border security.
