TDAC Explained: Thailand's Digital Arrival Card, Step by Step

1. Go to the official site

Type tdac.immigration.go.th into your browser yourself. Don't click a sponsored search result. Lookalike sites charge "processing fees" for a form that's free, and some harvest passport data.

2. Keep these ready

Your passport, your flight booking (the flight that lands in Thailand), and the name and full address of your first night's hotel, including postal code. On a Party Passport trip, that's the first hotel in your trip documents.

3. Personal details

• Family name, first name and middle name, exactly as they appear on your passport's photo page.
• Passport number, nationality (Indian), date of birth and gender.
• Occupation: pick the closest option from the dropdown.
• Visa number: leave it blank. Indians on visa-exempt entry don't have one.
• Phone number, email, and country and city of residence.

4. Trip details

• Date of arrival: the date you land in Thailand, not the date you leave India. Overnight flights often land the next morning.
• Mode of travel (air) and the flight number of the flight that actually lands in Thailand. If you connect in Singapore or Kuala Lumpur, it's the second flight.
• Country where you boarded that flight.
• Purpose of travel: holiday.
• Where you're staying: accommodation type and address, with province, district and sub-district picked from dropdowns plus a postal code. On a multi-stop trip, enter only your first night's hotel.

5. Health declaration

• Countries you've visited in the last 14 days.
• Whether you currently have any symptoms.

6. Check, submit, save the QR code

Check your name and passport number against the passport one last time, then submit. The confirmation arrives by email with a QR code. Screenshot it, and keep a printout or offline copy in case you have no data when you land.

Name doesn't match the passport

This is the most common reason a card fails at the automated gates. Copy your name exactly as printed. Don't add a surname your passport doesn't show, and don't use a nickname. Name and passport number can't be edited, so a wrong one means filing a new card.

Wrong arrival date

The card is tied to the date you enter. If your flight is rescheduled or lands after midnight, update the date on the official site before you fly.

Using the India departure flight

On a connecting itinerary, enter the flight that lands in Thailand and the country it departs from, not your first flight out of India.

Paying a lookalike site

The official TDAC is free. If a site asks for card details, you're in the wrong place.

Reusing an old card

Each entry into Thailand needs a new TDAC. Last year's card won't work for this trip.

What is the TDAC?

The Thailand Digital Arrival Card is a free online form that every non-Thai national has to submit before entering Thailand by air, land or sea. It replaced the old paper TM6 arrival card on 1 May 2025. It isn't a visa. Indians enter Thailand visa-free for up to 30 days (since 15 September 2026), and the TDAC is the one piece of paperwork that's left.

When can I fill in the TDAC?

Within the 3 days before you land in Thailand, counting the arrival day itself. If you land on 10 December, the form accepts your card from 8 December. It won't accept a submission earlier than that. There's no minimum, so filing on the day of travel works, but the day before your flight is the sensible time.

How much does the TDAC cost?

Nothing. The official site, tdac.immigration.go.th, is free and never asks for payment. Any site that charges you to 'process' a TDAC is a third-party service, and some are outright scams that collect passport data. Search results and ads often show these first, so type the official address yourself.

Can one person fill in the TDAC for the whole group?

Each traveller needs their own card, linked to their own passport, including children and infants. The official form does let one person add fellow travellers on the same flight to a single submission (guides report a limit of 10), and each person still gets their own QR code. Party Passport can't submit it for you. We send reminders and a walkthrough before every Thailand departure, but the details have to come from you.

What if I make a mistake on the TDAC?

Most fields, like flight number, arrival date, hotel, phone, email and health answers, can be edited afterwards with the update option on the official site. Your name, passport number, nationality and date of birth are locked. If one of those is wrong, submit a fresh card. The latest valid submission is the one that counts.

Do I need a TDAC if I'm only transiting through Bangkok?

Not if you stay airside and never pass through Thai immigration. You do need one if you clear immigration for any reason, for example switching between Suvarnabhumi and Don Mueang airports, collecting bags that weren't checked through, or checking in again for a separate low-cost flight to Phuket or Krabi.
