How to Submit Thailand Digital Arrival  Card 

Submitting the Thailand Digital Arrival Card (TDAC) is an online process for foreign  travelers entering Thailand. The official TDAC guide says travelers can submit their arrival  card information through the Immigration Bureau website, and the system supports both  individual submission and group submission.  

This page explains how the TDAC submission process works, what information you need,  what to check before submitting, and how to avoid common mistakes. 

Important Notice 

Thailand Digital Arrival Card (TDAC) is an independent informational and traveler  assistance Google Site. This site is created to help travelers understand TDAC submission  steps, prepare the correct details, avoid errors, and access helpful arrival guidance. 

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.” Travelers should understand that the official  TDAC process is free. Any independent service fee should be clearly disclosed as an  assistance, review, support, or optional travel-service fee — not as a government fee. 

Quick Answer: How to Submit TDAC 

To submit TDAC, travelers should prepare passport, personal, travel, accommodation, and  health declaration information, then complete the online arrival card form before entering  Thailand. The official guide says the submission process includes clicking the “Arrival  Card” button, entering personal and passport details, entering trip and accommodation  details, completing health status information, and submitting the form.  

Basic process: 

1. Prepare your passport and travel details  

2. Start the TDAC arrival card process 

3. Enter personal and passport information  

4. Add trip and accommodation details  

5. Complete health declaration information  

6. Review all details carefully  

7. Submit the form  

8. Save your confirmation or QR code

Before You Start TDAC Submission 

Before starting, keep all required information ready. This helps you complete the process  faster and reduces the chance of mistakes. 

Prepare: 

• 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 or Thailand address  

• Purpose of travel  

• Email address  

• Health declaration information  

• Details of family members, if applying together  

The official TDAC guide lists passport, personal, travel, accommodation, and health  declaration information as required for submission. 

Step 1: Start the Arrival Card Process 

The TDAC process starts by selecting the arrival card option on the official system. Travelers should make sure they are using the correct official channel and not a fake or misleading  website. 

Before entering details: 

• Check the website carefully  

• Read the instructions  

• Keep documents ready  

• Use a stable internet connection  

• Avoid public or unsafe Wi-Fi when entering passport details  

• Do not rush the process 

Because TDAC includes passport and travel information, travelers should be careful about  where they enter personal data. Recent reporting notes that Thailand’s Immigration Bureau  warned travelers about fraudulent TDAC websites falsely offering services for a fee. 

Step 2: Choose Individual or Group Submission 

The TDAC system supports both individual and group submission. Individual submission is  suitable if you are applying only for yourself. Group submission is useful for families,  friends, or travel groups entering Thailand together. 

Choose individual submission if: 

• You are traveling alone  

• You want to submit only your own details  

• Each traveler will complete their own form separately  

Choose group submission if: 

• You are traveling with family  

• You are submitting for children  

• You are helping elderly travelers  

• You are preparing details for a travel group  

• Multiple travelers share the same arrival and accommodation details  

The official guide says travelers can choose to submit or update their information and  includes both individual and group submission options. 

Step 3: Enter Personal Information 

Enter your personal details exactly as shown on your passport. This section is very important  because your TDAC information should match your travel document. 

You may need to enter: 

• First name  

• Middle name, if applicable  

• Last name / surname  

• Date of birth  

• Gender  

• Nationality  

• Country of residence  

• Passport number  

• Passport issue country  

Avoid:

• Nicknames  

• Short names  

• Wrong spelling  

• Wrong date of birth  

• Different name order  

• Incorrect nationality  

• Old passport details  

Step 4: Enter Passport Details 

Your passport details must be accurate. A mistake in passport number, name, date of birth, or  nationality can create confusion during travel. 

Check: 

• Passport number  

• Passport spelling  

• Full legal name  

• Nationality / citizenship  

• Date of birth  

• Passport issue country  

• Passport validity  

The official guide notes that travelers may enter passport details and may also scan or upload  the MRZ image to retrieve data automatically, where available. 

Step 5: Enter Trip Information 

After personal and passport details, enter your trip information. This tells immigration when  and how you are entering Thailand. 

Prepare: 

• Arrival date  

• 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 boarded  

• Purpose of travel  

Make sure your arrival date is correct. TDAC should be submitted within 3 days before  arrival in Thailand, including the arrival date.

Step 6: Enter Accommodation Information in Thailand 

Add the address where you will stay in Thailand. For tourists, this is usually the first hotel,  resort, villa, hostel, apartment, or residence after arrival. 

Prepare: 

• Hotel or accommodation name  

• Full address  

• Province or city  

• District or area, if available  

• Contact number, if available  

• First stay address if you have multiple hotels  

If you are staying with friends or family, enter the correct residential address in Thailand. If  your hotel changes after submission, you may need to update your TDAC before travel.

Step 7: Complete Health Declaration Information 

The TDAC process includes health declaration information. Answer this section honestly and  carefully. 

You may need to provide: 

• Countries visited before arrival  

• Country or place where you boarded  

• Recent travel history  

• Health declaration answers  

• Other health-related information requested by the system  

The official guide says travelers enter health status information as required by Thailand’s  Ministry of Public Health. 

Step 8: Review All Details Before Submitting 

Before submitting, review every detail carefully. This is one of the most important steps  because small mistakes may cause problems later. 

Check: 

• Name matches passport  

• Passport number is correct  

• Nationality is correct  

• Date of birth is correct 

• Arrival date is correct  

• Flight number is correct  

• Hotel address is complete  

• Email address is active  

• Children and family members are included  

• Health declaration details are accurate  

Do not submit until you are confident the details are correct.

Step 9: Submit the TDAC Form 

After reviewing all information, submit the TDAC form. Once submitted, keep your  confirmation safe. 

After submission: 

• Check the confirmation message  

• Check your email  

• Download the TDAC document, if available  

• Save the QR code, if provided  

• Take a screenshot  

• Keep a printed backup copy, if possible  

The official guide says travelers can download or print a copy from the email address  provided during submission and keep it during their stay in Thailand. 

Step 10: Save TDAC Confirmation for Travel 

After submission, your confirmation should be easy to access during your journey. Do not  rely only on internet access at the airport. 

Best practice: 

• Save the confirmation email  

• Download a copy to your phone  

• Take a screenshot  

• Save it offline  

• Print a backup copy  

• Share a copy with a family member if needed  

The official FAQ says travelers can present the downloaded document with QR code on a  mobile phone or other device, and printing is not mandatory but may be useful as backup.

How to Submit TDAC for Families 

If you are submitting for a family, prepare details for every traveler before starting. Children  and infants also need TDAC, so do not forget to include them. 

Prepare for each family member: 

• Passport details  

• Full name  

• Date of birth  

• Nationality  

• Arrival details  

• Accommodation address  

• Health declaration details  

Family submissions should be reviewed carefully person by person. One mistake in one  traveler’s passport or date of birth can create confusion later.

How to Submit TDAC for Groups 

For group travelers, collect all details before starting the process. This is useful for friends,  tour groups, business delegations, or organized travel groups. 

Before group submission: 

• Collect passport details from each traveler  

• Confirm arrival date and flight details  

• Confirm shared or separate accommodation  

• Check health declaration details  

• Use an active email address  

• Review each traveler’s information carefully  

The official guide includes a group submission option for TDAC. 

Can You Update TDAC After Submission? 

Yes. The official TDAC guide says submitted information can be updated anytime before  travel.  

You may need to update TDAC if: 

• Your hotel changes  

• Your flight changes  

• Your arrival date changes 

• Your Thailand address changes  

• Your travel route changes  

• You entered incomplete information  

• You notice a typing mistake  

However, some important identity details may be restricted, so always review carefully  before submitting. 

Common TDAC Submission Mistakes 

Avoid these common mistakes: 

• Using a nickname instead of passport name  

• Typing the wrong passport number  

• Choosing the wrong nationality  

• Entering the wrong arrival date  

• Forgetting children or infants  

• Entering incomplete hotel details  

• Using an email address you cannot access  

• Submitting without reviewing  

• Thinking TDAC is a visa  

• Not saving the confirmation  

• Using a fake or unofficial website without checking 

TDAC Submission Timing 

TDAC should be submitted within 3 days before your arrival date in Thailand. The arrival  date is included in this period.  

Best practice: 

• Prepare documents before the 3-day window  

• Submit once your eligible period opens  

• Do not wait until airport check-in  

• Save confirmation immediately  

• Update details if travel plans change before arrival  

TDAC Is Not a Visa 

TDAC is not a visa. It is an arrival card requirement. You must still check Thailand visa rules  based on your nationality, travel purpose, and length of stay. 

Before traveling, check: 

• Visa exemption eligibility  

• Visa-on-arrival eligibility  

• Tourist visa rules  

• Business visa rules  

• Student or long-stay visa rules  

• Passport validity  

• Return or onward travel requirements  

Completing TDAC does not guarantee entry into Thailand. Final entry permission is decided  by immigration authorities.

Safety Warning Before Submitting TDAC 

Travelers should be careful with websites that look official but charge fees or collect  sensitive passport information without clear disclosure. Thailand’s Immigration Bureau has  warned foreign travelers about fraudulent TDAC websites and emphasized that the official  TDAC process is free through official government channels.  

Before using any independent TDAC assistance site, check: 

• Clear disclaimer  

• Clear service fee disclosure  

• Privacy policy  

• Data protection policy  

• Contact details  

• Secure form handling  

• No false government branding  

• No guaranteed approval claim
