TDAC 2026: Official Guide to the Thailand Digital Arrival Card
2026 Official Regulation: The Thailand Digital Arrival Card (TDAC) permanently replaces the paper TM6 form for all international arrivals by air, sea, and land. Submissions must be completed exclusively online via the official Royal Thai Immigration portal (
tdac.immigration.go.th).
1. What is TDAC and Who is Required to Complete It?
The TDAC is the mandatory digital arrival declaration established by the Royal Thai Immigration Bureau. Every non-Thai traveler entering the Kingdom of Thailand must submit this form prior to border immigration clearance.
Who Must File the TDAC?
- Tourists entering under visa exemption (60 days) or Tourist Visa (TR).
- Long-term residents and visa holders (DTV, Non-Immigrant O, B, ED, LTR, Elite).
- Minors and children: Each traveler, regardless of age, must have an individual TDAC linked to their passport number.
Thai passport holders are exempt from filing the TDAC.
2. When and How to Submit Your TDAC?
The TDAC must be submitted within the 72-hour window prior to scheduled arrival in Thailand.
| Step | Timeline | Required Action |
|---|---|---|
| 1. Preparation | Day -7 to Day -3 | Gather: passport (valid > 6 months), flight number, 1st accommodation address in Thailand. |
| 2. Online Submission | Within 72h of departure | Visit tdac.immigration.go.th, fill out personal identity, flight details, and lodging info. |
| 3. QR Code Issuance | Instant | Download the confirmation PDF and save the QR Code to your mobile photo library. |
| 4. Border Clearance | Upon Arrival | Present the QR Code along with your passport at immigration counters or automated e-Gates. |
3. Required Information and Verification
Ensure you have the following details ready before starting:
- Biometric Passport: Passport number, issuance/expiry dates, nationality.
- Flight Details: Arrival flight number (e.g., TG931, EK384) and scheduled arrival date.
- Exact Address in Thailand: Hotel name, condominium or private residence, province (Changwat), district (Amphoe), and postal code.
- Contact Info: Valid email address and active mobile phone number.
Beware of Third-Party Scam Websites: The official TDAC application is 100% FREE OF CHARGE. Never enter payment details on unverified third-party websites claiming to charge "processing fees". The only authentic URL is
tdac.immigration.go.th.
4. Frequently Asked Questions (FAQ)
What should I do if my flight or hotel changes after submitting the TDAC?
You can log back into the official portal using your reference number and passport credentials to modify your flight details or initial accommodation address for free.
Does the TDAC replace a Thai Visa?
No. The TDAC is an arrival immigration declaration (landing card). It does not replace the visa requirements or visa exemptions governing your nationality.
Does TDAC replace the TM30 notification upon arrival?
No. The TDAC records your border crossing. The TM30 declaration remains strictly mandatory for your landlord or hotel within 24 hours of reaching your accommodation.
