Thailand TDAC Arrival Card: 2026 Online Guide

Hey there! I'm Nohtrip!

Have you ever traveled to Thailand and ended up huddled in a corner filling out your digital arrival card while everyone else breezed right on through?

Because I definitely have... haha.

So today, I’ve put together this guide to help you zoom through airport immigration as fast as possible!

When planning a trip to Thailand, entry documents can sometimes be way more confusing than booking flights or accommodation.

Lately, submitting the Thailand Digital Arrival Card (TDAC) online instead of the traditional paper arrival card has become the norm.

If it's your first time, you probably have a ton of questions: "When do I fill it out?", "How do I write my address in English?", or "Do I need to print it out?"

That’s why today, I'm going to walk you through a step-by-step guide on how to fill out the Thailand TDAC, making it super easy even for first-time visitors.

I'll also cover the trickiest parts that people often get stuck on, so reading this just once before you fly will make your prep a whole lot smoother!

What to Prepare Before Filling Out the Thailand TDAC

Before diving in, having these details ready to go will make the process incredibly smooth.

Since you'll need to enter your accommodation address in English, I highly recommend having your hotel booking page or Google Maps open and ready.

Step 1: Head to the Official Website

First things first, you need to access the official Thailand Digital Arrival Card (TDAC) portal.

⬇️⬇️⬇️⬇️

If you search "TDAC" online, several sites will pop up. Make sure you are clicking on the official site!

There are third-party agency sites with similar names that might charge you, so it's super important to double-check the URL.

Once you land on the site, make sure the language is set to English!

Then, you'll spot the prominent "Arrival Card" button right on the screen!

Just click on that button to start the registration process.

Step 2: Enter Your Personal Information

Now it's time to enter your passport details.

This section requires your name, nationality, passport number, and so on.

The most crucial part here is making sure the spelling matches your passport exactly.

Even a small mismatch in spacing or the order of your names can lead to hiccups during immigration.

So, the safest bet is to keep your passport open right next to you and copy the details character for character as you fill out the TDAC.

Also, double-check your date of birth format so you don't accidentally swap the month and day!

AND!

I found myself getting a bit stuck on the Nationality/Citizenship and Occupation fields.

For fields like nationality, if you search "KOREA", you can select options like

SOUTH KOREA

REPUBLIC OF KOREA

as shown in the image above!

And as for your occupation!

I’ve put together a handy table below.

The bolded rows are the most commonly used options, so feel free to use them as a reference!

Step 3: Entering Your Travel Details

Next up is entering your travel-related details.

You'll need to input your arrival/departure dates, flight number,

and your accommodation details in Thailand.

It’s super helpful to keep your flight confirmation email and hotel booking details open

on the side to avoid any typos!

In particular, make sure to enter your flight number accurately with both letters and numbers,

just like Korean Air (KE) or Jeju Air (7C).

Also, when filling out Thailand's Digital Arrival Card (TDAC),

entering your accommodation address is key.

Even if you're traveling across multiple cities, it's standard practice

to enter the details of your very first lodging.

First up is the arrival/departure section!

Just a heads up: Arrival = Arrival Information.

You actually don't need to fill out the departure info—

good to keep in mind!

Arrival Date = Your arrival date in Thailand

Country of Embarkation = KOREA (REPUBLIC OF KOREA)

I’ve mapped out the different purposes of travel in the table below:

Next up is the mode of transport!

For most of us, choosing the airplane option does the trick!

(Apologies to any seafarers or road-trippers out there! haha)

There are three different transport options available.

If you're flying on a regular commercial airline,

just select COMMERCIAL FLIGHT.

If you happen to be flying on a private jet, the second option is the one for you!

After that, you'll need to enter your accommodation info.

Check out the table below for a quick breakdown of the accommodation types:

You can use this table as a handy guide!

For the Province/State section, simply select the city you are heading to!

Such as Bangkok, Chiang Mai, Phuket, etc.

Then, just copy and paste the rest of your accommodation address!

Step 4: Health & Entry Questions Check

Depending on the current regulations, there might be questions

regarding your health status or recently visited countries.

If you select countries with no restrictions,

no extra questions will pop up. Just select the country,

click "Preview" for one final check, and you're good to go!

Step 5: Submit and Save

Once everything is filled out, you'll reach the final submission stage.

After submitting, a download link or confirmation email

will usually be generated.

Make sure to take a screenshot of this page!

For extra peace of mind, saving it as a PDF is highly recommended.

Since airport Wi-Fi can sometimes be patchy,

I strongly suggest saving a copy to your phone and taking a screenshot.

In fact, many travelers find themselves

unable to find their completed Thailand Digital Arrival Card (TDAC) confirmation,

which can lead to some stressful moments at the airport.

Common Mistakes When Filling Out the TDAC

Let's go over some of the most common slip-ups made by first-timers.

Specifically, rushing to fill out your Thailand TDAC

at the airport on your departure day

significantly increases the chance of making a mistake.

It's always best to get it done at least a day in advance!

It might seem a bit overwhelming at first, but once you start,

it's actually pretty straightforward.

As long as you have your passport, flight tickets, and accommodation details handy,

you can easily wrap it up in about 10 minutes.

The most crucial parts are entering your details accurately

and saving your confirmation after submission.

Just keeping these two things in mind will save you

a whole lot of stress at the airport.

If you're planning an upcoming trip to Thailand,

use this guide to fill out your

Thailand Digital Arrival Card (TDAC) ahead of time.

Sorting this out before you leave will make the start of your journey

so much smoother and more relaxing!
