The Thailand Digital Arrival Card (TDAC) is an online arrival form required for foreign  travelers entering Thailand. It replaces the old paper-based arrival card and helps make the  immigration entry process more organized, faster, and easier for visitors arriving in Thailand  by air, land, or sea. 

If you are planning to visit Thailand, you should prepare your TDAC details before your trip  and submit the information within the allowed time before 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.  

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 mistakes, and access 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 TDAC service is provided by the Thai Immigration Bureau. Travelers may  complete the official TDAC process directly through the official government system. The  official TDAC website also states that the TDAC service is available with no fees.  

What Is Thailand Digital Arrival Card? 

The Thailand Digital Arrival Card, also known as TDAC, is a digital arrival form used by  Thailand to collect important traveler information before entry. It includes details such as  passport information, personal details, arrival information, accommodation address in  Thailand, and health declaration details. 

TDAC is not a visa. It does not replace Thailand visa rules, visa exemption rules, visa-on arrival rules, or immigration officer decisions. It is a separate digital arrival requirement that  helps immigration officers verify traveler information more efficiently.

Who Needs TDAC? 

TDAC is required for all non-Thai nationals entering Thailand. This includes tourists,  business travelers, family visitors, students, long-stay travelers, visa-exempt travelers, and  visa-on-arrival travelers. 

You may need to complete TDAC if you are entering Thailand by: 

• International flight  

• Land border  

• Sea route  

• Private vehicle  

• Tour group  

• Family trip  

• Visa-on-arrival entry  

• Visa-exempt entry  

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

Do Children Need TDAC? 

Yes. Children and infants also need TDAC. If you are traveling with family, you should  prepare passport and travel details for every traveler, including babies and children. 

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

When Should You Submit TDAC? 

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

It is best to prepare your passport, flight, hotel, and travel details early, then submit TDAC  once your eligible submission period opens. This helps avoid last-minute mistakes, missing  hotel details, wrong flight numbers, or email issues.

Before starting TDAC, keep all your travel details ready. You may need: 

• Passport details
