I am a resident of New Zealand but my passport is Argentine, and I have not visited Argentina in the past two years. Do I still need to present a yellow fever vaccination certificate when filling out my TDAC and upon arrival in Thailand? I’ll be arriving on 9th of march I would greatly appreciate any guidance or recent experiences from travelers who have gone through this process. Thank you very much! 🙏
For the TDAC the Health Declaration is not required if you have not been there in the last 2 weeks.

someone told me to fill in the TDAC. So I Did immediately (stress) and filled in the wrong Arrival date. Because the original arriving day is 6 days old, I cannot update my TDAC. I go to Thailand in March and now I m aware that I have to fill the application 3 days before travelling. please can you help me? What do I have to do?
You should submit a new TDAC with the correct arrival details. The old one will be ignored if you have not entered on it.
I am a resident of Brazil and must urgently organize a business trip to Thailand for a time-sensitive meeting. My yellow fever vaccination is scheduled soon, but arrival would be only about 6 days later due to the sudden requirement. To assess if entry is feasible: Will the International Certificate of Vaccination be valid for TDAC and entry if fewer than 10 days have passed since vaccination? What outcome should I expect at immigration/health control (e.g., acceptance, mandatory on-arrival vaccination, quarantine duration, or denial)?
How can I cancel my application once submitted? I will not be traveling until 2027 and decided to cancel the trip. I sent an email to support but still haven’t heard anything back.
Just submit a new TDAC
I already paid and needed to get a refund…

Yes you can subit your TDAC again!
Ich habe bei der Card mein Vor- und Nachname vertauscht. Ist das ein Problem?
Ja, Sie sollten Ihren TDAC bearbeiten oder einen neuen einreichen.
Hiii, jika saya setelah tiba menginap 2 hari di pattaya dan melanjutkan menginap 4 hari di bangkok, apakah akomodasi bisa saya isi dengan nama akomodasi di bangkok?
Untuk TDAC, Anda hanya perlu memasukkan tempat Anda akan menginap pada malam pertama.
What should be filled in for a 3-year-old child’s occupation?
You can put NONE for your childs TDAC occupation
How is my personal information secured, and is it deleted after the TDAC submission is completed? If so, how long is the data retained before deletion?
Through the AGENTS TDAC system, there’s an option to delete your submission after it has been submitted. If you choose to do this, it will be removed immediately from all records.
Please note: once deleted, you won’t be able to look up or reuse that TDAC application for future trips to Thailand, since it will be permanently removed.
https://agents.co.th/tdac-applyI did not see the option to delete my submission…Could you please provide the steps details or a screenshot of where that option is located?
I stay in multiple places in diff cities, do I need to fill all of them in tdac ? Or just the 1st location ?
For the TDAC you only use the first.

My passport number is being transcribed incorrectly on the final document. Instead of the passport number it shows 21 after JC 60515.
Please do not share your TDAC number. You just need to submit a new TDAC form with the correct information.
My last name is not being fully transferred.
Your TDAC name must match the name in your passport.
Hello, I am going to Koh Samui. Do I only need to indicate the Paris–Bangkok flight, or both flights Paris–Bangkok and Bangkok–Koh Samui? Please, thank you.
If you have to go through immigration in Bangkok, indicate only the Paris–Bangkok flight for your TDAC.
Good evening, upon reaching the last page, the site freezes on the terms and conditions and I can no longer exit.
Please contact support@agents.co.thWhy the payment is being asked on completion of form
If you apply sooner than 72 hours before your arrival a small fee is charged for early submission for your TDAC. Otherwise you can just wait.
How do I cancel the application?
Do I need to pay to submit the application for entry into Thailand?
The TDAC is FREE OF CHARGE
Do I need to pay to submit the application for entry into Thailand?
if i fly from greece athens-istanbul -istanbul -bangkok which country will i write i have board from athens or istanbul
You would pick Istanbul for your departure country as it is the flight into Thailand for your TDAC.
I am planing to go to Thailand, stay for a month or two and then travel by train/bus up to Laos. Do I have to book a ticket for the train as close to the boarder as possible or do I have to show a ticker OUT of the country?
This is NOT related to the TDAC its related to the visa you would be entering on. If you do not have a long term visa you will need proof of return booked.

I'm currently in Thailand and have entered February 6 as my departure date on my TDAC. But I need to leave Thailand for four days in January and then return to Thailand. Should I change my TDAC?
You would need to submit a new TDAC. Once you enter on a TDAC it cannot be changed, and is only needed for each entry into Thailand. In your case you will be entering twice so you need TWO TDACS!
What should we write in the health declaration if we have not visited any other countries in the previous 2 weeks?
You should provide the country you are departing from for the TDAC if you have not traveled to any other country in the last 2 weeks.
Hello, I bought an outbound flight from Phuket to Bangkok to transfer and then return to Taiwan. For the outbound flight number and date, should I write the second flight segment? Thank you.
For the TDAC, only the flights directly entering or leaving Thailand are considered. Please ignore any domestic flights within Thailand.
Is travel insurance mandatory
No you do not need any travel insurance for the TDAC. However some visas do require insurance like the Retirement OA visa.
Hi, I am from Ecuador (yellow fever list) and planning to visit Thailand. I already got my vaccine but Ecuador does not use the classic yellow WHO vaccination book. Instead, it issues a URL that displays a document with the proof of the vaccine. The vaccination center told me it should be ok because it is an official document, however it is not the classic format. Is it likely that I will have a problem at the moment of presenting the certificate? Thanks!
For the TDAC this should be ok, just take a screenshot.
Hi, how are you supposed to present this digital arrival card, can you print it out on paper? When you arrive at passport control.
You can take a screenshot of your TDAC, or even print it out.
I would like to ask for your assistance regarding the completion of the TDAC form. My husband and I completed our TDAC forms for our arrival scheduled for tomorrow. However, in the meantime our original flight was cancelled and we were rebooked to a different flight. Using my digital card number, I was able to correct the flight number on my TDAC without any issue. Unfortunately, when I try to access my husband’s TDAC using his digital card number, the system cannot find his record. In this case, should I create a new TDAC application for my husband, or is there another way to correct the existing one? Thank you very much for your assistance.
You should just submit your TDAC again, it will not cause any issues as they only use the last submitted one.
Hello.. I want to edit the wrong flight number information but instead the hotel data entry doesn't appear.. and for arrival information, if we transit in Singapore, should we fill in the boarding information from Singapore or Indonesia?
You should try the Agents form it is more clear:
https://agents.co.th/tdac-applyMy name is Göran, how should I write my first name in the TDAC application form?
For your TDAC, use "o" instead of "ö" because only A–Z characters are allowed in the TDAC.
Hello, I have a French passport and I plan to leave for Thailand on 2 February 2026 and return to France on 19 April 2026, so a trip of about 75 days without a visa, as I intend to apply for an additional extension at the Kalasin immigration office when I am there. Do I need to indicate a return date to France on the TDAC application form? And if so, which one?
Yes, you must indicate a date of departure from Thailand on the TDAC application, even if you plan to extend your stay after your arrival. You should simply indicate the currently planned return date, which is 19 April 2026. The TDAC is not a visa but an administrative declaration, and the departure date is provided for information purposes only, without binding effect. Applying later for an extension of stay at the immigration office, for example in Kalasin, is a normal and accepted procedure, even if the actual departure date changes. As long as you have not already obtained an extension on a visa‑exempt entry, the extension is in principle granted without difficulty. Thai immigration officers are used to this type of situation and it generally does not cause any problems.
When filling out the TDAC, I entered my patronymic (middle name) in the “patronymic” field, even though this field is not mandatory. Is this a mistake?
When filling out the TDAC, you must indicate your full name. If you have a middle name or patronymic, it should be entered, even if the field is marked as optional. This is not a mistake.
It should not be complicated.
The TDAC is very simple.
What should I indicate on my TDAC knowing that I arrive in Bangkok on 13 January, then go to Vietnam for 1 month, then return to Thailand for 34 days? Thank you.
You will need to complete two TDAC forms, one for each entry into Thailand, and you will complete them separately since you will enter Thailand multiple times.
Good afternoon. I just want to clarify about my nationality. My passport was issued in Taiwan because I was working there. If I put Taiwan, my nationality is shown as Taiwan. What should I do?
If you do not hold a Taiwan passport then you have filled out your TDAC incorrectly, and should fill out another one.
I left Thailand on 7 December for China, and my flight back to Bangkok is on 25 December. I faced a problem with filling out the arrival card: when I enter the passport number I get a false remark.
You can try the agents TDAC system, it's free as well:
https://agents.co.th/tdac-applyHello, the Accommodation Information cannot be filled in, it is gray. What should I do?
It was my mistake. I filled the Departure section with the wrong date. I should have put my departure date from Thailand, not from my country. Because the section is misleading. Please write this notice in the application.
This is corrected in the agents TDAC system
Hello, I registered in TDAC with the return date of 6 January. I arrive 19 December but I want to stay 20 more days; in my passport I have to return 16 February. What do I need to do to change the date in TDAC?
Since you already entered using the TDAC you do not need to update it if your travel plans change. It is only required to be correct upon entry.
I have entered the wrong arrival and departure dates from Thailand in TDAC, what should I do?
Edit your TDAC to correct it, or submit again.
thank you

Merry Christmas, have a safe trip to Thailand and an easy TDAC
If you made two TDAC cards by mistake,
The last TDAC will remain valid, and the previous one will become invalid.
Hello, I am traveling to Thailand on January 3. I am leaving from Germany and I have a stopover in Qatar. Which country should I indicate as the country of departure? Also, I do not have a return flight. Can I book a flight to Malaysia to justify my onward travel?
You must select Qatar as the country of departure for your TDAC. If you benefit from an exemption, a return or onward flight is required; a flight to Malaysia is acceptable.
Thank you for the uptime page
If the system is not working you can use:
https://agents.co.th/tdac-applyFor example: Family name: Arvas First name: Mehmet Ali It is written like this in the passport. How should I write it on the TDAC? Family name: ………….. ? First name: ……………… ? Middle name: ……………. ? Thank you
For your TDAC you can enter your given name as Mehmet Ali and your surname/family name as Arvas.
No surname
For no surname you use "-"
