Thailand Digital Arrival Card (TDAC) – Complete Official Guide 2025

The Thailand Digital Arrival Card (TDAC) is the new mandatory online registration system that fully replaced the old paper TM6 arrival/departure card in 2025. It is 100% free and must be completed by every non-Thai traveler before entering the country.

What is the TDAC?

The TDAC is an electronic arrival card managed directly by the Immigration Bureau of Thailand. After completion, travelers receive a unique QR code by email that is scanned by immigration officers upon arrival. The system helps speed up border processing and replaces the previous paper forms that were handed out on flights.

Who Must Complete the TDAC?

• All foreign nationals entering Thailand by air, land, or sea
• Tourists on visa-exempt entry (60 days)
• Holders of any type of Thai visa (tourist visa, non-immigrant, DTV, LTR, etc.)
• Transit passengers who leave the international transit area
• Children and infants – each passport requires its own TDAC
• Cruise-ship passengers and overland border crossers

Only Thai passport holders are exempt.

When Should You Complete the TDAC?

You may submit the TDAC as early as 6 months before arrival. The official requirement is no later than 3 days (72 hours) before entering Thailand. Most travelers complete it 24–72 hours prior to their flight for maximum convenience.

Required Information & Documents

• Passport valid for at least 6 months from the date of arrival in Thailand
• Flight details (airline, flight number, arrival date and time)
• Address of first night’s accommodation in Thailand (hotel name + district or “Transit” if connecting)
• Clear photograph or scan of the passport biographical page (phone photo is accepted)
• Valid email address to receive the confirmation and QR code

Step-by-Step: How to Complete the TDAC (100% Free)

1. Visit the official government portal
   https://tdac.immigration.go.th
   Select “English” at the top of the page if needed.
2. Fill in your personal and travel details
   Enter full name exactly as in passport, nationality, date of birth, passport number, flight information, and accommodation details.
3. Upload a clear photo of your passport bio page
   A simple phone picture against a plain background works perfectly.
4. Review and submit
   The system will instantly send your unique QR code to the email address you provided.

The entire process takes 5–10 minutes and is completely free of charge.

What to Do After Receiving Your QR Code

• Save the email or take a screenshot
• Show the QR code (on your phone or printed) together with your passport at check-in and immigration
• If plans change (flight delay, new hotel, etc.), simply complete a new TDAC – the latest submission overrides previous ones

Frequently Asked Questions

Is the TDAC really mandatory?

Yes. Airlines will check it before boarding, and immigration officers will scan it upon arrival.

Can I complete it after landing in Thailand?

Technically possible, but not recommended due to limited Wi-Fi and long queues at the airport.

Do children need their own TDAC?

Yes – every passport requires its own QR code, including infants.

What if I make a mistake?

Simply submit a new corrected TDAC. Only the most recent one is valid.
