TDAC Thailand 2026: How to Fill It In Without Stress

The TDAC, Thailand Digital Arrival Card, has been mandatory for entering Thailand since May 1st, 2025. Here is everything you need to know to complete it correctly and travel with peace of mind.

You’re heading to Thailand. You’re already dreaming of turquoise beaches, golden temples, warm smiles and incredible flavours. The last thing you want is to find yourself stuck in front of an administrative form to fill out on your phone, the night before departure, hoping you don’t make a mistake.

That’s exactly why we’re here.

What exactly is the TDAC?

Since May 1st, 2025, Thailand has taken an important step forward in modernising its tourism entry process by introducing the TDAC — Thailand Digital Arrival Card. This online form replaces the old TM6, that small paper card filled out in a hurry on the plane, often with a borrowed pen, in turbulence, with barely legible handwriting.

The TDAC is a real improvement. Everything is done online, from your phone or computer, calmly, before you even board the plane. Thailand has chosen to simplify and secure entry into the country for all foreign travellers, and that is a decision worth acknowledging.

It is not a visa. It is not an entry permit. It is a mandatory digital arrival declaration, required for every foreign traveller regardless of nationality or visa status.

The 72-hour window: the critical point many travellers miss

This is without doubt the most important thing to remember about the TDAC.

The form can only be submitted to the Thai authorities within the 72 hours before your arrival. Not before. This window is set by the Thai authorities and is non-negotiable.

Concretely, if your flight lands on a Friday at 2pm, the official submission can only take place from Tuesday at 2pm onwards. Not on Sunday when you are thinking about getting everything organised. Not on Monday evening while you are packing your bags.

This timing constraint is precisely what causes the most problems for travellers. You forget, you get caught up in the rush of departure, you realise too late. And that is when the stress kicks in.

This is where our service comes in.

With thailandentry.com, you can submit your file to us up to  months before your departure. Today if you wish. Your application is registered, secured, and placed in our priority processing queue. You no longer have anything to monitor or manage. When the official 72-hour window opens, our team submits your file automatically, on time, without you having to lift a finger.

You pack your bags. We handle the rest.

Why is it important to fill it in correctly?

The TDAC is an official document checked upon your arrival in Thailand. And as with any administrative process, it is better to approach it calmly rather than in a rush.

The information must match your passport: your name, your document number, its expiry date. These are straightforward details, but best entered carefully rather than in a hurry on your phone at the last minute.

This is where our two services make complete sense.

Are you organised and planning your trip well in advance? Our Standard service at $29.90 is made for you. Submit your file up to 12 months before departure, we register it, secure it, and submit it at the right time without you having to think about it.

More of a last-minute person, or simply been caught up with other things? Our Emergency service at $59.90 is there for exactly that. Absolute priority processing, your file is submitted within 4 hours of the official window opening. Because even under pressure, you deserve everything to go smoothly.

What happens after submission?

Once your TDAC has been submitted, you will receive your confirmation directly by email, sent from the official address noreply@tdacservices.immigration.go.th.

One important tip: remember to check your spam folder. This type of automated email sometimes ends up in junk mail, and it is better to know that before arriving at the airport.

Your TDAC comes in the form of a QR code. This is the document you will be asked to present upon arrival in Thailand. We strongly advise you not to rely solely on keeping it on your phone. Print it out. A dead battery, a phone with no signal, and you find yourself in an uncomfortable situation. A single printed sheet in your carry-on bag means complete peace of mind.

The TDAC for the whole family

The TDAC is mandatory for every traveller entering Thailand, without exception. This includes children, regardless of age. Each family member must have their own TDAC, issued in their name and matching their personal passport.

The good news is that you do not have to re-enter everything from scratch for each person. Information shared across the whole family, the flight, dates and accommodation, is common to all. Only the details specific to each traveller, first name, last name and passport number, need to be entered individually. A real time-saver when travelling as a family.

Simply have everyone’s passports to hand before you start, and the whole process takes just a few minutes.

Is our service legitimate? 

The question deserves a straight answer.

Online, whenever a paid assistance service exists, there will always be someone crying foul. That is the reality of the internet, and we respect it.

Yes, the TDAC can be completed for free on the official Thai government website at tdac.immigration.go.th. We say so ourselves, clearly, on every page of our site. We have nothing to hide.

But the world is made up of different kinds of people. Some are perfectly comfortable with online administrative processes, have plenty of time, and have no problem managing everything themselves. That is great, the official website is made for them.

Others prefer to delegate so they can travel with a clear head from the very start, or simply do not want to think about it. That is a personal choice, and a perfectly legitimate one.

Using an assistance service is completely normal. Nobody asks their plumber to justify their fees just because YouTube has free tutorials.

We are transparent, legally compliant, and proud of the service we provide. ThailandEntry exists for those who have chosen to travel differently: peacefully.

Ready for Thailand?

Thailand is waiting for you. The TDAC is just one of many steps in preparing for a trip, nothing more, nothing less. What matters is remembering to do it on time, filling it in with care, and leaving with your mind already elsewhere, soaking up the warmth and the smiles of the Land of Smiles.

If you would like to hand off this step and forget about it, our team is here for that.
