How to fill in the TDAC (Thailand Digital Arrival Card): step by step

Fill in the Thailand Digital Arrival Card (TDAC) for free at tdac.immigration.go.th within 3 days before your arrival in Thailand, including your arrival date. It takes around 3–5 minutes per person if you have your information ready. You'll need your passport details, travel information, accommodation address and health declaration. Once submitted, you'll receive a QR code by email. Download it or save a screenshot on your phone to show immigration when you arrive.

What the TDAC is and who needs it

The Thailand Digital Arrival Card replaced the paper arrival form on 1 May 2025. Every foreign traveller needs one, children and babies too, whether you arrive by air, land or sea. It is not a visa.

You don't need one if you are only in transit and don't pass through Thai immigration, if you hold a Border Pass, or if you are crew on duty.

When to fill it in

You can submit your TDAC within 3 days before your arrival date, including the day you land.

For example, if you arrive on 30 December, you can submit your form from 27 December.

Our tip? Do it before leaving for the airport. You can also complete it on arrival, but having your QR code ready makes things easier.

It is free: watch out for fake sites

The TDAC is completely free. The only official website is tdac.immigration.go.th.

Be careful with third-party websites that charge a fee to complete the form for you. Some may look official, but you don't need to pay anyone to submit your TDAC.

If a website asks you to pay for the arrival card, stop and check the URL.

Step 1: Personal and passport details

Visit tdac.immigration.go.th and click "Arrival Card".

Choose between individual submission or group submission (up to 10 travellers per application).

Fill in your personal information and passport details, including:

• Full name (exactly as shown in your passport)
• Passport number
• Date of birth (Dates are written day/month/year)
• Nationality
• Occupation
• Country and city of residence
• Phone number

You can scan your passport's machine-readable zone (MRZ) to fill in some details automatically. Always double-check the information before moving on.

Tip: All information must be entered in English.

Step 2: Your trip and where you stay

Next, enter your travel information:

• Arrival date in Thailand
• Country where you boarded
• Flight or vehicle number
• Purpose of your visit
• Departure information, if available

Then add your accommodation details in Thailand.

Select your accommodation type, such as a hotel, apartment or private residence. Enter the province, district and address where you'll be staying.

Where should you put the address?

• Hotel: Use the full address from your hotel booking confirmation.
• Airbnb: Use the property address provided by your host.
• Staying with friends: Ask your friend for their complete residential address before filling in the form.

Make sure the address matches where you'll actually be staying.

Step 3: The health declaration

The next section is the health declaration.

You'll need to list the countries you visited during the 14 days before arriving in Thailand.

Depending on your travel history, nationality, country of departure or flight, the system may ask additional health-related questions.

For example, travellers arriving from countries on Thailand's yellow fever risk list may need to provide vaccination information.

Answer all questions honestly and provide any additional information requested by the system.

Step 4: Submit and save the QR code

Before submitting, carefully review all your information, especially your passport number, arrival date and accommodation address.

Then:

1. Enter your email address.
2. Accept the terms and conditions.
3. Click "Submit".
4. Download your completed TDAC and QR code.

A copy will also be sent to your email.

Our tip: Save the QR code as a screenshot or download the PDF to your phone. You don't need to print it, but having an offline copy is useful if you don't have internet access at the airport.

When you reach immigration, have your passport and TDAC QR code ready.

Keep a copy for the duration of your stay.

Made a mistake or changed your plans?

Plans change. That's okay!

If your flight, arrival date or accommodation changes, you can use the "Update Arrival Card" option on the official TDAC website before entering Thailand.

You'll need your TDAC number, date of birth and nationality to retrieve your submission.

Some personal details cannot be edited, including:

• Full name
• Passport number
• Nationality
• Date of birth

If any of these details are incorrect, submit a new TDAC with the correct information. The latest valid submission will be used.

Remember, each TDAC is valid for one trip only. If you leave Thailand and return later, you'll need to complete a new one.

Travelling with children

Travelling with little ones? Don't forget their TDAC! Every foreign traveller needs their own TDAC, including babies and children. Parents or guardians can complete the form on their behalf using the group submission option.

You can submit up to 10 travellers in one application, which makes it easier for families travelling together.
