Before submitting the Thailand Digital Arrival Card (TDAC), travelers should keep all  required documents and travel details ready. TDAC is an online arrival card required for non Thai nationals entering Thailand, and the official guide says travelers must prepare  passport, personal, travel, accommodation, and health declaration information before  submission.  

This page explains the documents and details you should prepare before starting your TDAC  application so you can avoid mistakes, delays, and last-minute confusion. 

Important Notice 

Thailand Digital Arrival Card (TDAC) is an independent informational and traveler assistance Google Site. This site is not the official Thai Immigration website, not a  government authority, and not affiliated with Thai Immigration, any embassy, or any  government department. 

The official TDAC website states “No Fees”, so travelers should understand that the official  TDAC process is free. Any independent service fee should be clearly explained as an  assistance, review, support, or optional travel-service fee — not as a government fee.  

Quick TDAC Document Checklist 

Before starting your TDAC application, keep these ready: 

• Valid passport  

• Full name as shown on passport  

• Nationality / citizenship  

• Date of birth  

• Passport number  

• Arrival date in Thailand  

• Flight number or travel details  

• Hotel booking or Thailand address  

• Email address  

• Health declaration details  

• Recent travel history  

• Details of children or family members, if traveling together  

• Visa details, if applicable  

TDAC should be submitted 3 days before arrival in Thailand, so it is better to prepare these  details early and submit once your eligible window opens.  

1. Valid Passport 

Your passport is the most important document for TDAC. The details you enter must match  the passport you will use to enter Thailand. 

Prepare:

• Passport number  

• Full name exactly as printed on passport  

• Nationality / citizenship  

• Date of birth  

• Gender  

• Passport issue country  

• Passport expiry date, if requested  

Use your legal passport name, not a nickname, short name, social media name, or different  spelling. Even a small mismatch in passport number, name, nationality, or date of birth can  create confusion during travel.

2. Personal Information 

TDAC requires your personal information so your arrival record can be matched with your passport and travel details. 

Prepare: 

• First name  

• Middle name, if applicable  

• Last name / surname  

• Date of birth  

• Gender  

• Nationality  

• Country of residence  

• Occupation, if requested  

• Contact details, if requested  

Always enter your information exactly and carefully. If your passport has a middle name or  multiple surnames, follow the same format shown on your passport.

3. Travel Information 

You need to provide your Thailand arrival information. This helps immigration understand  how and when you are entering Thailand. 

Prepare: 

• Arrival date in Thailand  

• Mode of arrival: air, land, or sea  

• Flight number, if arriving by air  

• Border checkpoint, if arriving by land  

• Vessel or sea travel details, if arriving by sea  

• Country or place where you are boarding from 

• Purpose of travel  

Travelers entering Thailand by land, air, or sea are required to submit TDAC unless they fall  under a specific exemption such as transit without passing through immigration. 

4. Flight Ticket or Transport Details 

If you are arriving by air, keep your flight ticket or booking confirmation ready. Your flight  number should match your actual arrival flight into Thailand. 

Prepare: 

• Airline name  

• Flight number  

• Arrival airport  

• Arrival date  

• Arrival time, if required  

• Departure country  

• Connecting flight details, if relevant  

If you are entering by land or sea, prepare your checkpoint, vehicle, cruise, or vessel details  where applicable.

5. Hotel Booking or Thailand Address 

You must provide your accommodation information in Thailand. For most travelers, this will  be a hotel, resort, villa, apartment, hostel, or first confirmed stay after arrival. 

Prepare: 

• Hotel or accommodation name  

• Full address in Thailand  

• Province / city  

• District or area, if available  

• Contact number, if available  

• Booking reference, if useful  

If you are staying with friends or family, use the correct residential address. If you will stay at  multiple hotels, use the first confirmed address where you will stay after arriving in Thailand.

6. Health Declaration Information

TDAC includes health declaration information. The official guide says travelers may be  asked to provide health information as required by Thailand’s Ministry of Public Health,  depending on factors such as countries visited, boarding country, nationality, or flight.  

Prepare: 

• Recent countries visited  

• Travel history before arrival  

• Country or place where you boarded  

• Health declaration answers  

• Any additional health-related information requested  

Answer all health declaration questions honestly and accurately. Do not guess or provide  false information.

7. Recent Travel History 

Some travelers may need to provide information about countries visited before arriving in  Thailand. This is usually connected to health declaration and arrival screening requirements. 

Prepare: 

• Countries visited before Thailand  

• Approximate travel dates  

• Country where you boarded your Thailand-bound flight  

• Transit country, if applicable  

If you recently traveled through multiple countries, keep your itinerary ready before starting  the form.

8. Active Email Address 

You need an email address that you can access while traveling. This email may be used to  receive your TDAC confirmation or related document. 

Use an email address that: 

• Is active  

• Is typed correctly  

• You can open on your phone  

• Does not have inbox access issues  

• Is not temporary or disposable  

• Can receive attachments or confirmation messages 

After submission, check your inbox, spam folder, and junk folder. Save a copy of your  confirmation so it is easy to access during travel.

9. Details for Children and Infants 

Children and infants also need TDAC. If you are traveling as a family, prepare the details for  every child before starting. 

Prepare for each child: 

• Passport number  

• Full name as shown on passport  

• Date of birth  

• Nationality  

• Arrival date  

• Flight or travel details  

• Accommodation address 

• Health declaration details  

The official TDAC FAQ confirms that all travelers, including infants and children, are  required to have a TDAC.

10. Details for Family or Group Travel 

If you are traveling with family, friends, or a tour group, keep everyone’s details organized  before submission. This will help avoid missing information. 

Prepare for each traveler: 

• Passport details  

• Personal information  

• Arrival details  

• Accommodation address  

• Health declaration details  

• Email contact  

• Relationship or group details, if needed  

For group travel, create a simple checklist before submission and review each traveler’s  information one by one. 

11. Visa Details, If Applicable

TDAC is not a visa. It does not replace Thailand visa rules, visa exemption rules, visa-on arrival rules, or immigration decisions. 

Depending on your nationality and travel purpose, you may still need: 

• Visa exemption eligibility  

• Visa on arrival  

• Tourist visa  

• Business visa  

• Student visa  

• Long-stay visa  

• Re-entry permit  

• Work permit, if applicable  

The official FAQ notes that TDAC is compatible with all visa types, including visa-on-arrival  and visa-exempt entries. 

12. Documents to Keep After Submission 

After completing TDAC, save your confirmation carefully. You may need to show it during  travel or at immigration. 

Keep: 

• TDAC confirmation email  

• Downloaded TDAC document  

• QR code, if provided  

• Screenshot on your phone  

• Printed backup copy, if possible  

• Passport  

• Flight ticket  

• Hotel booking  

• Visa document, if applicable  

The official FAQ says travelers should download the document with the QR code and can  show it on a phone or other device; printing can also be useful as a backup. 

Best Way to Prepare Before Applying 

Before applying, create a folder on your phone or computer with your important travel  documents. This makes the process easier and reduces the chance of mistakes. 

Recommended folder items: 

• Passport photo page 

• Flight ticket  

• Hotel booking  

• Visa document, if applicable  

• Travel insurance, if applicable  

• Emergency contact  

• TDAC confirmation after submission
