As of May 1, 2025, the Thai authorities are reintroducing the requirement to complete the Thailand Digital Arrival Card (TDAC) – a digital arrival form that replaces the previous paper-based TM6 form. This document is not a visa, but it is a must-have registration document for anyone entering the country. It needs to be filled out before you arrive.
Key Information at a Glance
- Fill out the form online at: tdac.immigration.go.th
- Take a screenshot or download the confirmation – you’ll need to show it at passport control and possibly when departing Thailand, too.
- It is recommended to complete the form 72–24 hours before fly.
What is TDAC?
The TDAC (Thailand Digital Arrival Card) is an electronic form that must be completed before travelling to Thailand. It captures your basic details: passport number, travel dates, reason for visiting, and where you’ll be staying in Thailand. It’s the new, fully digital upgrade to replace the previously used TM6 paper form.
How to Apply for TDAC?
You must complete the form online before arrival in Thailand. The process is free and easy:
- Go to the official TDAC website
- Click „Arrival Card“
- Enter the required information: full name, passport number, flight details, planned address of your stay in Thailand, etc.
- Submit the form and download the confirmation – as a PDF or a screenshot. Saving it offline is recommended, as it may be needed both upon arrival and departure.
- Present the confirmation when you go through border control in Thailand.
When Should You Complete the TDAC?
There’s no strict deadline, but it is recommended to complete the form:
- No earlier than 72 hours before departure,
- No later than a few hours before your flight.
This helps avoid unnecessary stress or delays at the airport.
Can I Fill Out the TDAC Form on My Phone?
Yes, the official TDAC website is mobile-friendly and works well on smartphones and tablets. You can easily fill it out from anywhere with an internet connection.
Tip: After submitting the application, save the confirmation – preferably as a PDF or screenshot. It will make border checks smoother.
Can Airlines Ask for TDAC?
Yes, some airlines may request to see the TDAC confirmation during check-in, before boarding your flight to Thailand. So keep it handy.
What If I Forget to Complete the TDAC?
Forgetting the TDAC does not automatically mean you’ll be denied entry, but it may:
- Cause delays at passport control
- Require you to complete the old paper-based TM6 form (if still available)
- Lead to additional document checks
Filling out the TDAC online is faster and highly recommended.
Travelling with Family or in a Group?
- Each adult must complete their own TDAC form
- Children can usually be included in their guardian's form – the system typically allows this.
Do I Need to Print the TDAC?
Printing is not required. A digital version – such as a PDF or a screenshot saved on your phone – is sufficient. Just make sure it’s saved somewhere digitally - so that you can access it offline.

A Few Extras Worth Knowing:
- Travellers are legally obliged to respect the monarchy – insulting the royal family (even jokingly) is a criminal offence punishable by imprisonment.
- Thailand enforces strict laws regarding e-cigarettes – possession and use are illegal and may result in high fines or even detention. It’s best to leave them at home.
What to Know Before Flying to Thailand?
When planning your trip to Thailand, it’s wise to prepare not only formally but also culturally and practically.
Here are a few key tips:
- Currency: The official currency is the Thai Baht (THB). Credit cards are widely accepted in cities and resorts, but in smaller towns, it’s better to carry cash.
- Health: While not mandatory, vaccinations against Hepatitis A and B, tetanus, and typhoid are recommended. Also, pack mosquito repellent – Thailand is a tropical country.
- Temple etiquette: When visiting temples, cover your shoulders and knees, and remove shoes before entering. Respect for Buddhism is very important.
- Rainy season: The rainy season runs from May to October. Although the showers are usually short, they can be intense – a light raincoat or umbrella is useful.
- Local Transport: Tuk-tuks are a colourful and popular mode of transport, but always agree on the price before the ride.
If you're heading to Thailand, the TDAC is a small step that saves big hassle. Get it done early for a smooth journey.
