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.
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.

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 "-"
Hello 1 - I am going from Türkiye to Iran on a different plane. On the same day, without leaving the airport, I will go to Bangkok on a flight from Iran. country/territory where you boarded: Should I write Türkiye for this, or Iran? 2 - please list the name of the countries/territories where you stayed within two weeks before arrival Similarly: Should I write Türkiye or Iran? Thank you for your help
1) For your departure country, write the country you are flying from as shown on your arrival ticket. 2) For the countries where you stayed, write ALL of them, including your transit/connecting flights.
What to do if surname is blank
Then you enter "-", only a dash for the TDAC.
Hi there, I hold a Dutch passport and my partner holds a Bolivian passport. She has lived with me in the Netherlands for almost two years. Do we need to report to the Department of Disease Control? We are arriving from the Netherlands, which is not a yellow-fever country.
The yellow fever requirement is not based on passport, it is based on recent travel for the TDAC. So if you were only in the Netherlands she will NOT need a health certificate for the TDAC.
Thank you AGENTS!
We have a group with a cruise in Asia, and our clients arrive in Thailand in Koh Samui by sea cruise ship in Nathon and then go to Laem Chabang, Bangkok. What address should I mention in the application for arrival at, and for departure from, Thailand in the TDAC then? Thanks
For your TDAC, you enter the first address where they will spend the night after arrival, or the port.
Good afternoon. We arrive in Bangkok on January 3 and then we continue on a domestic flight to Chiang Mai. Should we complete the TDAC to present it in Bangkok or in Chiang Mai?
You must submit your application as Bangkok, since the TDAC is only required for entering the country.
If I go to Thailand and stay there for 3 days and register for the tdac form, and then I go to Hong Kong and want to return to Thailand again, do I have to register for the tdac again?
Yes, you must have a NEW TDAC for each entry into Thailand.
Do I have to pay for the TDAC?
TDAC is free of charge.
Why was I asked for money, 10 dollars, in order to proceed with submitting the application?
After registrering . When Will i get the qr code ?
If your arrival is within 72 hours, your TDAC will be issued in about 1 to 3 minutes. If your arrival is more than 72 hours away, it will be issued during the first 1 to 3 minutes after your arrival time enters the 72-hour window.
Hello, I am flying on December 5. I have just completed the form and paid 8 dollars, but I made a mistake. I filled it out again from the beginning and paid another 8 dollars, and now I have filled it out correctly. Will I have any problem because there are 2 TDACs submitted under my name? Which one will be considered?
Contact us at support@agents.co.th at this address. Two earlier TDAC submissions are not necessary.
It would have been easy to correct the previous application, so now just write an email and they will refund the amount you paid the second time.
Also, having multiple TDACs is not a problem. They will always consider the last, most recently submitted one.If, when I arrive at Suvarnabhumi Airport, the internet is not working, can I show a printed TDAC to the officer? (I want to be prepared in advance.) Thank you.
Take a screenshot or print the QR code from the TDAC.
Do I have to pay some taxes at the airport when I leave Thailand? In which currency is it possible
No, there is no fee to leave Thailand, and the TDAC has nothing to do with exiting the country. If anything, you might actually get money back. You can apply for a VAT refund at the VAT Refund counter for tourists at Suvarnabhumi Airport.
Flying from Dubai to Bangkok. During the last 15 days I have been in Uruguay (residing) and in transit 9 hours in a Brazilian airport. Do I need a yellow fever vaccine?
Yes, for your TDAC you do need it, as you were in Brazil, as per: https://www.mfa.go.th/en/publicservice/5d5bcc2615e39c306000a30d?cate=5d5bcb4e15e39c30600068d3
There was a mistake in my name when I filled in the TDAC form, can it be corrected? Or do I need to submit a new TDAC?
You can submit an edit, or copy the previous application and submit a new one if you are using the AGENTS system:
https://agents.co.th/tdac-applyHello.. my accommodation address in Thailand has already been filled in. The field cannot be clicked, but the barcode has been issued. Do I need to fill it out again or can I use the one that has already been issued?
Accommodation information for your TDAC is required if you are staying more than 1 day in Thailand.
I tried to submit but I see a system error on the .gov TDAC url.
It appears the TDAC page is down on the .go.th domain, hopefully it will be back soon.
In the meantime you still can submit for FREE here:
https://agents.co.th/tdac-apply
Your TDAC will be immediately processed once the system is back.We are Italian citizens resident in Montevideo, Uruguay. We are flying from Uruguay to Dubai, UAE, with a flight change in Sao Paulo, Brazil, 9 hours in transit. After 4 days we fly to Bangkok. Do we need a yellow fever vaccine because we are going to be in transit in a Brazilian airport?
If your last flight is from Brazil to Thailand then you use Brazil for your TDAC (look at the flight number).
