Complete your Thailand Digital Arrival Card (TDAC) preparation with clear step-by-step  guidance before entering Thailand. TDAC is an online arrival card required for non-Thai  nationals entering Thailand before arrival, and official guidance says travelers should  submit arrival card information within 3 days before arrival in Thailand.  

This page helps you understand what information is required, how to prepare your details  correctly, and what to check before submission so your arrival process in Thailand is  smoother and more organized. 

Important Notice Before Applying 

Thailand Digital Arrival Card (TDAC) is an independent informational and traveler  assistance Google Site. This site is created to help travelers understand TDAC requirements,  prepare the correct information, avoid common mistakes, and get useful 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 Thailand Digital Arrival Card system is provided by Thai Immigration, and the  official TDAC website states “No Fees.” Any service fee charged by an independent  assistance provider should be clearly disclosed as a fee for guidance, review, support, or optional travel services — not as a government fee. 

Who Can Use This TDAC Application Page? 

This page is useful for travelers who want simple guidance before submitting their TDAC  details. It is suitable for: 

• Tourists visiting Thailand  

• Business travelers  

• Family travelers  

• Group travelers  

• Visa-exempt travelers  

• Visa-on-arrival travelers  

• Students and long-stay visitors  

• Travelers entering by air, land, or sea  

TDAC is required for foreign travelers entering Thailand, and the official TDAC guide says  all non-Thai nationals entering the Kingdom of Thailand must complete TDAC online before  entry.  

Before You Start Your TDAC Application 

Before starting, keep your travel details ready. This will help you avoid typing mistakes,  missing information, or last-minute confusion. 

You should prepare: 

• Valid passport  

• Full name exactly as shown on passport  

• Nationality / citizenship  

• Date of birth  

• Passport number  

• Arrival date in Thailand  

• Flight number or travel details  

• Hotel name or Thailand accommodation address 

• Purpose of travel  

• Email address  

• Health declaration information 

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

Step 1: Enter Traveler Details 

Start by entering your personal and passport information exactly as shown on your passport.  This is one of the most important parts of the TDAC process because incorrect passport or  identity details may create problems during travel. 

Check carefully: 

• Passport number  

• First name  

• Middle name, if applicable  

• Last name / surname  

• Nationality  

• Date of birth  

• Gender  

• Passport issue country  

Avoid using nicknames, short names, spelling variations, or names that do not match your  passport. 

Step 2: Add Trip and Arrival Information 

Next, provide your Thailand arrival details. This usually includes your arrival date, transport  method, and flight or vehicle information. 

You may need to enter: 

• Arrival date  

• Mode of travel: air, land, or sea  

• Flight number, if arriving by air  

• Border checkpoint, if arriving by land  

• Vessel or transport information, if arriving by sea  

• Country or place from where you are arriving  

• Purpose of travel  

Your arrival date is especially important because TDAC should be submitted within the  correct time window before travel.

Step 3: Add Accommodation Details in Thailand 

You will need to provide your address in Thailand. For most tourists, this will be the hotel,  resort, apartment, villa, or private residence where they will stay after arrival. 

Prepare: 

• Hotel or accommodation name  

• Province / city  

• District or area, if available  

• Full address, if available  

• Contact number, if available  

If you are staying with friends or family, use the correct residential address in Thailand. If  you are changing hotels during your trip, use the first confirmed address where you will stay  after arrival. 

Step 4: Complete Health Declaration Information 

The TDAC process includes health declaration information. You should answer this section  carefully and truthfully based on your recent travel and health-related details. 

You may need to provide: 

• Recent countries visited  

• Travel history details  

• Health declaration answers  

• Other required arrival-related information  

Do not guess or enter false information. Health declaration information should be accurate at  the time of submission. 

Step 5: Review Before Submission 

Before submitting your TDAC, carefully review every detail. Many traveler issues happen  because of small mistakes in passport number, spelling, nationality, arrival date, or hotel  address. 

Check these details again: 

• Name matches passport  

• Passport number is correct  

• Nationality is correct  

• Date of birth is correct 

• Arrival date is correct  

• Flight number is correct  

• Thailand address is complete  

• Email address is active  

• Children and infants are included, if traveling with family  

A careful review can help reduce the risk of delay, confusion, or needing corrections later. 

Step 6: Save Your TDAC Confirmation 

After submission, keep your TDAC confirmation safely. You may need to show the  confirmation or QR code when traveling or entering Thailand. 

Best practice: 

• Save a digital copy on your phone  

• Take a screenshot  

• Keep the email confirmation  

• Print a backup copy, if possible  

• Share a copy with your travel partner or family member  

Even if a printed copy is not always required, having a backup can be helpful if your phone  battery is low, internet is unavailable, or you cannot access your email quickly. 

TDAC Application for Families and Groups 

If you are traveling with family or a group, every traveler should have accurate TDAC  information. This includes children and infants. 

For family and group preparation, collect details for each person: 

• Passport details  

• Full legal name  

• Date of birth  

• Nationality  

• Arrival date  

• Flight or travel details  

• Accommodation address  

• Health declaration details  

The official TDAC system supports both individual and group submission. 

Can You Update TDAC After Submission? 

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

You may need to update TDAC if: 

• Your hotel changed  

• Your flight changed  

• Your arrival date changed  

• Your Thailand address changed  

• You made a typing mistake  

• Your travel plan changed before arrival  

However, some key personal information may not be editable in the same way, so it is always  better to review everything carefully before submission. 

Common Mistakes to Avoid While Applying 

Avoid these mistakes when preparing TDAC: 

• Using a nickname instead of passport name  

• Typing the wrong passport number  

• Selecting the wrong nationality  

• Choosing the wrong arrival date  

• Entering incomplete hotel details  

• Using an inactive email address  

• Forgetting children or infants  

• Submitting outside the correct timing  

• Thinking TDAC is the same as a visa  

• Not saving the confirmation after submission  

TDAC is an arrival card requirement, not a visa approval. You must still follow Thailand’s  visa, visa-exemption, or visa-on-arrival rules based on your nationality and travel purpose.
