Planning a trip to Thailand soon?
Until recently, entering Thailand was very straightforward—but in the past few years, the country has started introducing new digital systems designed to streamline the process.
Don’t worry—it sounds more complicated than it actually is.
Here’s a clear, up-to-date guide to what you actually need before entering Thailand.
What’s new for entering Thailand?
Thailand is gradually introducing two systems:
-
TDAC (Thailand Digital Arrival Card) – already in use
-
ETA (Electronic Travel Authorization) – planned for the future
👉 The important part: only one of these is currently relevant for most travelers.
1. Thailand Digital Arrival Card (TDAC)
What is it?
The TDAC is an online entry form that replaces the old paper arrival card.
👉 It is required for all travelers entering Thailand.
When should you fill it out?
You should complete it:
👉 Within 72 hours (3 days) before your arrival
It only takes a few minutes, but it’s important not to forget it.
What information do you need?
The form is simple and straightforward.
You’ll typically be asked for:
-
Passport details
-
Flight information
-
Your first accommodation in Thailand
-
Travel dates
-
Basic contact details
👉 Everything is standard—nothing complicated.
What happens after you submit it?
Once completed, you’ll receive a digital confirmation.
-
No need to print anything
-
Just keep it on your phone
-
Immigration can usually access it digitally
How much does it cost?
👉 The TDAC is completely free
2. ETA (Electronic Travel Authorization)
What is it?
The ETA is a planned system, similar to the U.S. ESTA or Europe’s upcoming ETIAS.
It is expected to apply to travelers who currently enter Thailand without a visa.
Do you need it right now?
👉 No.
As of now, the ETA system is not fully implemented and is not required for most travelers.
That’s why many people (like you) have recently entered Thailand without ever hearing about it.
So why is everyone talking about it?
Because it has been officially announced and is expected to roll out in the future.
Some websites already present it as active, but in practice, it’s still in the process of being introduced.
What should you do?
👉 For now: nothing.
But:
-
Check for updates close to your travel date
-
Especially if you’re traveling later in the year or planning ahead
3. Do you still need a visa?
That depends on your nationality.
-
Many travelers can enter Thailand under a visa exemption
-
Others may need a Visa on Arrival or a tourist visa in advance
👉 Always check based on your passport before traveling.
4. Other entry requirements (that still matter)
Even without a visa, you may still be asked for:
-
A passport valid for at least 6 months
-
An onward or return ticket
-
Accommodation details
-
Occasionally, proof of funds
👉 These are not always checked—but you should have them ready.
In short, what you actually need to do
Before your trip:
✔️ Check visa requirements for your nationality
✔️ Complete the TDAC form (within 72 hours)
✔️ Make sure your passport is valid
✔️ Have your flight and accommodation details ready
👉 And that’s it.
Final tip
Thailand is still one of the easiest countries to enter in Southeast Asia—but it’s no longer a “just show up” destination.
A few minutes of preparation before your flight can save you a lot of stress at the airport.
👉 Do the form, keep everything accessible on your phone, and you’ll walk through immigration smoothly.
Frequently Asked Questions About Thailand Entry (TDAC & ETA)
Do I need to print the TDAC form?
No, you don’t need to print anything.
After submitting the form, you’ll receive a digital confirmation. In most cases, immigration officers can access it in their system.
👉 That said, it’s always a good idea to keep a screenshot or email confirmation on your phone, just in case.
What happens if I forget to fill out the TDAC?
If you forget to complete the TDAC before your flight, you may be asked to fill it out at the airport before passing through immigration.
This can delay your entry—especially if there’s a queue or limited internet access.
👉 The easiest solution: just complete it in advance and avoid the hassle.
Do I need the TDAC if I’m only transiting through Thailand?
No.
If you’re only transiting and not going through immigration (i.e., you stay in the international transit area), you don’t need to complete the TDAC.
Is Thailand introducing a visa or ETA system?
Thailand has announced plans to introduce an Electronic Travel Authorization (ETA) system in the future.
👉 However, as of now, it is not required for most travelers.
If and when it becomes mandatory, travelers will need to apply for approval before boarding their flight—but for now, you can travel without it.
Do I still need a visa to enter Thailand?
It depends on your nationality and how long you plan to stay.
Many travelers can enter Thailand under a visa exemption, while others may need a visa in advance or qualify for a Visa on Arrival.
👉 Always check the latest requirements based on your passport before traveling.
What documents should I have ready at the airport?
Even if you don’t need a visa, it’s smart to have the basics ready:
-
A passport valid for at least 6 months
-
An onward or return ticket
-
Your first accommodation details
👉 You may not be asked for everything—but if you are, it’s best to have it ready.
Is the TDAC required for land border crossings too?
Yes.
The TDAC applies to entry by air, land, and sea, so you’ll still need to complete it even if you’re crossing into Thailand overland.
