Malay How to Fill Out the Thailand Digital Arrival Card
Complete step-by-step guide to filling out your TDAC correctly and efficiently
Introduction to 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 replaced the traditional paper TM6 form on May 1, 2025.
The TDAC streamlines the immigration process by allowing travelers to submit their information online prior to arrival, whether entering by air, land, or sea. This digital approach enhances efficiency at immigration checkpoints and improves border security.
By completing the TDAC correctly, you ensure a smooth entry into Thailand and avoid potential delays or complications at immigration. This guide will walk you through every step of the process.
