The Thailand Digital Arrival Card (TDAC) is a mandatory online immigration form introduced on 1 May 2025, replacing the traditional paper-based TM6 arrival card. All non-Thai nationals entering Thailand by air, land, or sea are required to complete the TDAC within three days prior to their arrival. The form collects personal details, travel and accommodation information, and a health declaration. Upon submission, travelers receive a confirmation with a QR code, which must be presented at immigration checkpoints.
What You Need to Know:
- TDAC is mandatory for all foreign travelers.
- You must register within 3 days before your arrival in Thailand.
- The process is fully online—no printing required.

What if you forget?
If you arrive in Thailand without completing the TDAC, expect delays at immigration. You may be asked to complete the process on arrival, which could slow down your entry or lead to denied boarding by your airline.
Play it safe—fill out your TDAC before you fly!
