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 rules, prepare 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.

Travelers should be careful with TDAC-related websites. Thailand’s Immigration Bureau has warned foreign travelers about fraudulent websites falsely offering TDAC services for a fee, while emphasizing that the official process is mandatory but free through official government channels. 

General TDAC Questions

1. What is TDAC?

TDAC stands for Thailand Digital Arrival Card. It is an online arrival card system for foreign travelers entering Thailand. It replaces the old paper arrival card process and allows travelers to submit required arrival information before entering Thailand.

2. Is TDAC required for Thailand?

Yes. TDAC is required for all non-Thai nationals entering Thailand. The official guide says all non-Thai nationals entering the Kingdom of Thailand must complete the Thailand Digital Arrival Card online before entry. 

3. Is TDAC a visa?

No. TDAC is not a visa. It is an arrival card requirement. Travelers must still follow Thailand visa, visa-exemption, visa-on-arrival, work permit, or long-stay rules based on their nationality and travel purpose.

4. Does TDAC guarantee entry into Thailand?

No. TDAC does not guarantee entry into Thailand. Final entry permission is decided by immigration authorities at the checkpoint. TDAC is only one part of your travel preparation.

5. Is TDAC free?

Yes. The official TDAC website states “No Fees.” Travelers can complete the official TDAC process through the Thai Immigration Bureau’s official system without paying a government fee. 

6. Can an independent service charge a TDAC assistance fee?

An independent service may charge for extra assistance, review, support, form guidance, travel add-ons, or customer service. However, this must be clearly disclosed as a service fee, not a government fee. The official TDAC itself has no fee on the official government website. 

TDAC Submission Timing Questions

7. When should I submit TDAC?

You should submit TDAC within 3 days before arriving in Thailand, including the arrival date. The official FAQ confirms that the card should be submitted within 3 days in advance of arriving in Thailand, including the arrival date. 

8. Can I submit TDAC on the same day as arrival?

Yes, because the arrival date is included in the 3-day submission period. However, it is better to submit earlier within the allowed window so you have time to review details, save confirmation, and correct mistakes if needed.

9. Can I submit TDAC one week before arrival?

You should follow the official 3-day submission rule. You can prepare your passport, flight, hotel, and health declaration details earlier, but submit TDAC during the allowed period before arrival.

10. Do I need a new TDAC every time I enter Thailand?

Yes. TDAC is for a specific expected arrival date. If you leave Thailand and enter again later, you should submit a new TDAC for the next entry.
