Thailand Digital Arrival Card Guide 

The Thailand Digital Arrival Card (TDAC) is an online arrival card system for foreign  travelers entering Thailand. It replaces the old paper arrival card process and allows travelers  to submit important entry information before reaching immigration. The official TDAC guide  states that all non-Thai nationals entering Thailand must complete the Thailand Digital  Arrival Card online before entry.  

This guide explains what TDAC is, who needs it, when to submit it, what information is  required, how to avoid common mistakes, and what travelers should keep ready before  arriving in Thailand. 

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 requirements,  prepare the correct information, avoid common 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”, so travelers should understand that TDAC  itself is not a paid government form. If any independent service charges a fee, it should be  clearly explained as an assistance, review, support, or travel service fee — not as a  government fee. 

What Is Thailand Digital Arrival Card? 

The Thailand Digital Arrival Card, also called TDAC, is a digital arrival information form  used by Thailand for foreign visitors. Instead of filling out a paper arrival card at the airport  or border checkpoint, travelers submit their arrival details online before entering Thailand. 

TDAC helps collect important information such as: 

• Passport details  

• Personal information  

• Arrival information  

• Accommodation address in Thailand  

• Health declaration details  

• Travel purpose  

• Contact details  

TDAC is designed to make Thailand’s arrival process more organized and digital. The  Tourism Authority of Thailand also describes TDAC as a required online form for non-Thai  nationals entering Thailand by air, land, or sea.  

Is TDAC a Visa? 

No. TDAC is not a visa. 

TDAC is only an arrival card requirement. It does not replace Thailand visa rules, visa  exemption rules, visa-on-arrival rules, work permit rules, or immigration officer decisions. 

Travelers still need to check whether they require: 

• Visa exemption 

• Visa on arrival  

• Tourist visa  

• Business visa  

• Student visa  

• Long-stay visa  

• Re-entry permit  

• Work permit, if applicable  

Even if your TDAC is completed, immigration entry approval is still decided by the  competent immigration authorities at the time of arrival. 

Who Needs Thailand Digital Arrival Card? 

TDAC is required for non-Thai nationals entering Thailand. This includes travelers visiting for tourism, business, family visits, medical travel, education, events, short stays, or  long stays. 

You may need TDAC if you are: 

• A tourist entering Thailand  

• A business traveler  

• A family visitor  

• A student  

• A long-stay traveler  

• A visa-exempt traveler  

• A visa-on-arrival traveler  

• A foreign resident returning to Thailand  

• A traveler entering Thailand by air, land, or sea  

The official TDAC FAQ confirms that foreigners entering Thailand by land, air, or sea must  submit TDAC.  

Do Children and Infants Need TDAC? 

Yes. Children and infants also need TDAC. 

If you are traveling with family, you should prepare TDAC details for every traveler,  including babies and children. Parents or guardians should make sure each child’s passport  details, arrival date, accommodation address, and required travel information are entered  correctly. 

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

When Should You Submit TDAC? 

Travelers should submit TDAC within 3 days before arriving in Thailand, including the  arrival date. For example, if you are arriving in Thailand on 20 June, you should prepare to  submit TDAC during the eligible 3-day period before your arrival. 

The official TDAC guide states that foreigners are required to submit arrival card information  3 days in advance of their arrival date in Thailand.  

Best practice: 

• Prepare documents early  

• Check your flight and hotel details before submission  

• Submit once your eligible 3-day window opens  

• Do not wait until the last minute  

• Save your TDAC confirmation after submission  

What Information Is Required for TDAC? 

Before starting the TDAC process, keep all details ready. The required information may  include passport, personal, travel, accommodation, and health declaration details. 

Prepare the following: 

Passport Information 

• Passport number  

• Full name as shown on passport 

• Nationality / citizenship  

• Date of birth  

• Gender  

• Passport issue country

The official guide mentions passport information, personal information, travel information,  accommodation information in Thailand, and health declaration information as part of the  TDAC submission process.  

How the TDAC Process Works 

The TDAC process is usually simple when your details are ready. Travelers should carefully  enter the required information, review it, submit it, and save the confirmation. 

A simple process looks like this: 

Step 1: Prepare Your Documents 

Keep your passport, flight details, hotel booking, and email address ready before starting.

Step 2: Enter Personal Details 

Fill in your name, passport number, nationality, date of birth, and other personal details  exactly as shown on your passport. 

Step 3: Enter Arrival Details 

Add your arrival date, travel method, flight number, border entry point, or transport details. 

Step 4: Enter Thailand Address 

Provide the hotel, residence, or first accommodation address where you will stay after arrival. 

Step 5: Complete Health Declaration 

Answer the required travel and health declaration questions honestly. 

Step 6: Review and Submit 

Check all information carefully before submitting. 

Step 7: Save Confirmation

Keep your TDAC confirmation, email, or QR code ready for travel.

TDAC for Families and Groups 

Families and groups should prepare traveler information for each person before starting. This  helps avoid missing details and makes the process smoother. 

For family and group TDAC preparation, collect: 

• Passport details for every traveler  

• Date of birth for each traveler  

• Nationality for each traveler  

• Same or different hotel address  

• Flight details  

• Health declaration details  

• Email address for confirmation  

The official guide supports both individual and group TDAC submission. 

TDAC for Transit Passengers 

Transit rules depend on whether you pass through immigration. 

If you are only connecting through Thailand and do not pass through immigration, TDAC  may not be required. If you leave the airport, enter Thailand, collect baggage and re-check in,  stay at a hotel, or pass immigration control, TDAC is required. 

The official FAQ says TDAC is not required if you are not passing through immigration, but  it is required if you leave the airport. 

Can You Update TDAC After Submission? 

Yes. Some TDAC information can be updated before travel. This is useful if your hotel  changes, flight changes, arrival date changes, or you notice an error after submission. 

You may need to update TDAC if: 

• Your hotel changed  

• Your arrival flight changed  

• Your arrival date changed  

• Your Thailand address changed  

• You entered incomplete accommodation details 

• You made a typing mistake  

• Your travel plan changed before arrival  

However, important identity fields may not be editable in the same way, so always review  your details carefully before submitting. 

Common TDAC Mistakes to Avoid 

Many travelers make small mistakes while completing arrival information. These errors can  create confusion during travel. 

Avoid these common TDAC mistakes: 

• Entering a nickname instead of passport name  

• Typing the wrong passport number  

• Selecting the wrong nationality  

• Choosing the wrong arrival date  

• Entering the wrong flight number  

• Using an email address you cannot access  

• Leaving hotel address incomplete  

• Forgetting children or infants  

• Assuming TDAC is a visa  

• Not saving the confirmation  

• Waiting until the last minute  

Always check your passport, flight ticket, and hotel booking before submitting. 

What to Do After TDAC Submission 

After completing TDAC, keep your confirmation safe. You may need to show it during travel  or when requested by airline staff or immigration officers. 

Recommended steps after submission: 

• Save the TDAC confirmation email  

• Take a screenshot of the QR code, if provided  

• Download a copy to your phone  

• Print a backup copy, if possible  

• Keep passport and travel documents together  

• Make sure your email is accessible while traveling  

• Share a copy with a family member if traveling in a group 

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

TDAC and Thailand Visa Rules 

TDAC does not replace a visa. Travelers must separately check whether they are eligible for  visa exemption, visa on arrival, tourist visa, business visa, or another visa category. 

Before travel, check: 

• Your nationality  

• Your purpose of visit  

• Your length of stay  

• Your visa exemption eligibility  

• Your visa-on-arrival eligibility  

• Passport validity  

• Return or onward travel requirements  

• Hotel booking and funds, if required  

TDAC is only one part of the Thailand entry preparation process.
