Before entering Thailand, foreign travelers should understand the main Thailand Digital  Arrival Card (TDAC) requirements. TDAC is an online arrival card required for non-Thai  nationals entering Thailand, and the official TDAC website states that foreigners must  submit their arrival card information 3 days in advance of their arrival date in Thailand.  

This page explains who needs TDAC, what documents and details are required, when to  submit it, and what travelers should check before arrival. 

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 disclosed as an  assistance, review, support, or travel-service fee — not as a Thai government fee. 

Who Must Meet TDAC Requirements?

TDAC requirements apply to foreign travelers entering Thailand. This includes tourists,  business travelers, family visitors, students, long-stay travelers, visa-exempt travelers, and  visa-on-arrival travelers. 

You should prepare TDAC if you are entering Thailand by: 

• Air  

• Land  

• Sea  

• International flight  

• Land border checkpoint  

• Cruise or sea route  

• Private or group travel  

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

Basic TDAC Eligibility Requirement 

The main TDAC requirement is simple: you must be a non-Thai national entering  Thailand. Thai nationals do not need TDAC, but foreign nationals entering Thailand should  complete it before arrival. 

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

Passport Requirements for TDAC 

Your passport details are one of the most important parts of the TDAC process. The  information should match your passport exactly. 

Prepare: 

• Passport number  

• Full name as shown on passport  

• Nationality / citizenship  

• Date of birth  

• Gender  

• Passport issue country  

• Passport expiry details, if requested  

Do not use nicknames, short names, spelling changes, or different name formats. Your TDAC  details should match the passport you will use to enter Thailand.

Personal Information Required for TDAC 

TDAC requires basic personal information to identify the traveler. Enter all details carefully  and consistently. 

You may need: 

• First name  

• Middle name, if applicable  

• Last name / surname  

• Date of birth  

• Nationality / citizenship  

• Gender  

• Passport information  

• Contact email  

The official TDAC guide says travelers enter personal information, including passport  details, during the arrival card process.  

Travel Information Required for TDAC 

Travelers must provide arrival-related information for Thailand. This helps immigration  understand when and how the traveler is entering the country. 

Prepare: 

• Arrival date in Thailand  

• Mode of travel: 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  

The official TDAC guide says travelers must enter trip information and accommodation  information as part of the submission process.  

Accommodation Information Required for TDAC 

You should provide a valid address in Thailand. For most visitors, this will be the hotel,  resort, apartment, villa, hostel, or first accommodation after arrival.

Prepare: 

• Hotel or accommodation name  

• Thailand address  

• Province / city  

• District or area, if available  

• Contact number, if available  

• First stay address if you have multiple hotels  

If you are staying with family or friends, use the correct residential address in Thailand. If  you are staying in multiple places, use the first confirmed address after arrival. 

Health Declaration Requirement 

TDAC may require health-related declaration information. The official TDAC guide says  travelers enter health status information as required by Thailand’s Ministry of Public Health,  and the system may ask for necessary health information depending on recent travel,  nationality, boarding country, or flight.  

Prepare: 

• Countries visited before arriving in Thailand  

• Country or place where you boarded  

• Recent travel history  

• Health declaration answers  

• Any additional information requested by the system  

Always answer health declaration questions truthfully and accurately. 

Email Requirement 

You need an active email address to receive your TDAC confirmation. Use an email address  you can access while traveling. 

Best practice: 

• Use your own active email  

• Check spelling before submission  

• Avoid temporary email addresses  

• Check spam or junk folder  

• Save the confirmation email  

• Download or screenshot the TDAC confirmation 

The official TDAC guide says travelers enter an email address to receive the Thailand Digital  Arrival Card and can download or print a copy from the provided email address during their  stay in Thailand.  

TDAC Timing Requirement 

TDAC should be submitted within the allowed period before arrival. The official TDAC  website says foreigners are required to submit their arrival card information 3 days in  advance of their arrival date in Thailand.  

Best practice: 

• Prepare documents before the 3-day window opens  

• Submit once you are within the eligible period  

• Do not wait until airport departure time  

• Review your details before submitting  

• Save your confirmation immediately  

Example: If you arrive in Thailand on 20 June, prepare your documents earlier and submit  TDAC during the eligible 3-day period before your arrival. 

TDAC Requirement for Children and Infants 

Children and infants also need TDAC. Parents or guardians should prepare passport and  travel details for each child before submitting. 

For children, prepare: 

• Passport number  

• Full name as shown on passport  

• Date of birth  

• Nationality  

• Arrival details  

• Accommodation address  

• Health declaration details  

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

TDAC Requirement for Families and Groups

If you are traveling with family or a group, each traveler should have correct TDAC  information. The official TDAC guide supports both individual and group submission, and  the group process allows travelers to add other travelers after entering the first traveler’s  details.  

For group preparation, collect: 

• Passport details for every traveler  

• Personal details for every traveler  

• Shared or separate accommodation details  

• Arrival flight or transport details  

• Health declaration information for each traveler  

• Email address for confirmation  

Make sure every traveler’s details are reviewed before final submission. 

TDAC Requirement for Transit Passengers 

Transit passengers only need TDAC in certain cases. If you are transiting through Thailand  without passing immigration, TDAC is not required. If you leave the airport or pass through  immigration, TDAC is required.  

You may need TDAC if: 

• You collect baggage and re-check in  

• You exit the airport  

• You stay at an airport hotel outside immigration  

• You pass through immigration control  

• You enter Thailand before taking another flight  

You may not need TDAC if you remain airside and do not pass through immigration. 

TDAC Requirement for Visa-on-Arrival and Visa-Exempt  Travelers 

TDAC is separate from visa rules. Visa-on-arrival and visa-exempt travelers still need to  complete TDAC if they are foreign nationals entering Thailand. The official FAQ confirms  that TDAC is compatible with all visa types, including visa-on-arrival and visa-exempt  entries.  

Before traveling, check: 

• Whether your nationality needs a visa  

• Whether you qualify for visa exemption 

• Whether visa on arrival is available  

• Passport validity  

• Return or onward ticket requirements  

• Hotel booking or address proof, if needed  

TDAC does not guarantee entry. Final permission to enter Thailand is decided by  immigration authorities at the checkpoint. 

TDAC Is Not a Visa Requirement Replacement 

TDAC is an arrival card, not a visa. Completing TDAC does not mean your visa is approved,  your visa exemption is guaranteed, or your entry is automatically accepted. 

Travelers should separately check: 

• Thailand visa rules  

• Visa exemption rules  

• Visa-on-arrival rules  

• Length of stay permission  

• Passport validity  

• Re-entry permit rules, if applicable  

• Work, study, or long-stay visa requirements  

Use TDAC as one part of your Thailand entry preparation, not as a replacement for visa  checking. 

Documents to Keep Ready Before Applying 

Before starting TDAC, keep these documents and details ready: 

• Passport  

• Flight ticket or arrival details  

• Hotel booking or Thailand address  

• Email address  

• Travel purpose  

• Recent travel history  

• Details for all family members  

• Visa details, if applicable  

• Contact number, if available  

Having these ready can help you complete the form more accurately.

Common TDAC Requirement Mistakes 

Avoid these common mistakes: 

• Entering a name that does not match the passport  

• Typing the wrong passport number  

• Selecting the wrong nationality  

• Using the wrong arrival date  

• Entering incomplete hotel details  

• Forgetting children or infants  

• Using an email address you cannot access  

• Thinking TDAC is a visa  

• Submitting without reviewing  

• Not saving the confirmation  

A small typing mistake can create confusion during travel, so always review your details  before submission.
