✈️ What is the Thailand Digital Arrival Card (TDAC)?

The Thailand Digital Arrival Card (TDAC) is an online immigration form that all foreign travelers must complete before entering Thailand.

It was officially introduced on 1 May 2025, replacing the old paper-based TM6 arrival form that passengers used to fill out on flights.

👉 In simple terms:
The TDAC is your digital entry form that must be submitted before arrival in Thailand.

📌 Why Did Thailand Introduce TDAC?

The Thai government launched TDAC to:

• Speed up immigration processing
• Reduce paperwork at airports
• Improve traveler tracking and safety
• Create a more digital and efficient entry system

👉 For travelers, this means:

• Faster airport experience
• Less hassle on arrival
• No more filling forms on the plane

---

✅ Is TDAC Mandatory for Travelers?

Yes — the TDAC is mandatory for all foreign travelers entering Thailand.

This includes:

• Tourists
• Business travelers
• Families and children
• Long-term visa holders

👉 Important:
Every individual traveler must submit their own TDAC form.

🕒 When Should You Fill the TDAC?

You must complete the TDAC within 72 hours (3 days) before your arrival in Thailand.

Example:

• Arrival date: 10 June
• You can submit: 7 June onward

❗ Submitting too early may invalidate your form, so timing is important.
