Do you still need to have the health declaration form approved even if you have the TDAC confirmed?
The TDAC is the health declaration, and if you have traveled through any of those countries which require additional details then you will have to provide them.
WHAT DO YOU PUT COUNTRY OF RESIDENCE IF YOU ARE FROM THE US? IT WON'T POPULATE
Try typing USA in the country of residence field for the TDAC. It should show the correct option.
I went to THAILAND with the TDAC in June and July 2025. I plan to return in September. Can you tell me the procedure? Do I need to submit a new application? Please inform me.
You must submit a TDAC for each trip to Thailand. In your case, you will therefore need to complete another TDAC.
I understand that travelers transiting through Thailand do not need to complete the TDAC. However, I have heard that if one leaves the airport briefly to visit the city during transit, the TDAC must be completed. In this case, would it be acceptable to complete the TDAC by entering the same date for both the arrival and departure dates and by proceeding without providing accommodation details? Or, is it the case that travelers who leave the airport only for a short visit to the city do not need to complete the TDAC at all? Thank you for your assistance. Best regards,
You are correct, for the TDAC if you are transiting you first enter the same date of departure as your date of entry, and then the accommodation details are no longer needed.
which number must be written in the visa slot if you have a yearly visa and also a re entry permit
For the TDAC the visa number is optional, but if you see it you can omit the /, and only enter the numeric parts of the visa number.
Some of the items I enter are not reflected. This applies to both smartphones and PCs. Why?
What items are you referring to?
How many days early can I apply for my TDAC?
If you apply for the TDAC through the government portal, you're limited to submitting it only within 72 hours of your arrival. In contrast, the AGENTS system was created specifically for tour groups and allows you to submit your application up to a year in advance.
Thailand now requires travelers to complete a Thailand Digital Arrival Card for faster entry processing.
The TDAC is an improvement over the old TM6 card, but the best and fastest entry process was during the period when neither the TDAC nor TM6 was required.
Fill out your Thailand Digital Arrival Card online before traveling to save time at immigration.
Yes, it’s a smart idea to complete your TDAC in advance. There are only six TDAC kiosks at the airport, and they’re almost always full. The Wi-Fi near the gate is also very slow, which can make things even more difficult.

If you need assistance, please contact [email protected].Hello, My son entered Thailand with his TDAC on July 10 and indicated his return date as August 11, which is the date of his return flight. However, I have seen in several sources that seem official that the first TDAC application cannot exceed 30 days and that it must be extended afterwards. Yet, upon arrival, immigration services validated his entry without any issue, even though from July 10 to August 11 is more than 30 days—about 33 days. Does he need to do anything, or is nothing required? Since his current TDAC already indicates departure on August 11... Also, if he misses his return flight and is delayed and needs to stay a few extra days, what should be done regarding the TDAC? Nothing? I have read in several of your responses that once entry into Thailand is made, nothing else needs to be done. But I don't understand this 30-day issue. Thank you for your help!
This situation has nothing to do with the TDAC, as the TDAC does not determine the authorized length of stay in Thailand. Your son does not need to take any further steps. What matters is the stamp placed in his passport upon arrival. It is very likely that he entered under the visa exemption scheme, which is common for French passport holders. Currently, this exemption allows a stay of 60 days (instead of the previous 30), which explains why he had no problem despite dates exceeding 30 days. As long as he respects the exit date indicated in his passport, no further action is necessary.
Thank you very much for your response, which helps me. So, if for any reason the indicated deadline of August 11 is exceeded, what steps should my son take? Especially if it is an unplanned overstay of the exit date from Thailand? Thank you again in advance for your next response.
It seems there is some confusion. Your son actually benefits from a 60-day visa exemption, which means his expiration date should be September 8, not August. Ask him to take a photo of the stamp placed in his passport upon arrival and send it to you; you should see a date in September indicated there.
It says the application is free, so why do I have to pay?
Submitting your TDAC within 72 hours after arrival is free of charge.
I registered but have to pay over 300 baht, do I need to pay?
Submitting your TDAC within 72 hours after arrival is free of charge.
Hello, I would like to ask on behalf of my friend. My friend is entering Thailand for the first time and is an Argentinian national. Of course, my friend must complete the TDAC 3 days before arriving in Thailand and submit the TDAC on the day of arrival. My friend will be staying at a hotel for about one week. If my friend is leaving Thailand, is it necessary to apply for or complete the TDAC? (For departure) I really want to know this because there is only information about entry. What should be done for departure? Please kindly reply. Thank you very much.
TDAC (Thailand Digital Arrival Card) is required only for entering Thailand. It is not necessary to complete the TDAC when departing from Thailand.
I have submitted the application online 3 times and I immediately receive an email with the QR code and a number, but when I try to scan it, it does not work no matter what I try. So is that a good sign or not?
You do not need to submit the TDAC repeatedly. The QR code is not intended for you to scan yourself; it is for immigration to scan upon arrival. As long as the information on your TDAC is correct, everything is already in the immigration system.
Although I have filled it in, I still cannot scan the QR code, but I did receive it by email, so my question is, can they scan the QR code?
The TDAC QR code is not a scannable QR code for you. It represents your TDAC number for the immigration system and is not intended for you to scan yourself.
Is it necessary to provide return flight details when filling out the TDAC? (Currently, there is no return date set.)
If you do not yet have a return flight, please leave all fields in the return flight section of the TDAC form blank. You can then submit the TDAC form as usual without any issues.
Hello! The system does not find the hotel address, I write as indicated in the voucher, I just entered the postcode, but the system does not find it, what should I do?
Postcode may be slightly off due to sub districts. Try entering the province and seeing the options.
Hello, my question is about the address of the hotel I have booked in Pattaya City. What else do I need to include?
I paid more than $232 for two TDAC applications because our flight was only six hours away and we assumed the website we used was legitimate. I am now seeking a refund. The official government site provides TDACs at no cost, and even the TDAC Agent does not charge for applications submitted within the 72-hour arrival window, so no fee should have been collected. Thank you to the AGENTS team for supplying a template I can send to my credit-card issuer. iVisa has yet to reply to any of my messages.
Yes, you should never pay more than $8 for early TDAC submission services.
There is a whole TDAC page here which lists trusted options:
https://tdac.agents.co.th/scamI have a flight from Jakarta to Chiang Mai. On the third day, I will fly from Chiang Mai to Bangkok. Do I also need to fill out the TDAC for the flight from Chiang Mai to Bangkok?
TDAC is only required for international flights to Thailand. You do not need another TDAC for domestic flights.
hello i wrote exit date on 15. but now i want to stay until 26. do i need to update the tdac? i changed my ticket already. thanks
If you are not yet in Thailand then yes you need to modify the return date.
You can do this by logging into https://agents.co.th/tdac-apply if you used agents, or logging into https://tdac.immigration.go.th/arrival-card/ if you used the official government TDAC system.I was filling accommodation details. I am going to stay in Pattaya but it is not showing under province drop-down menu. Please help.
For your TDAC address have you tried choosing Chon Buri instead of Pattaya, and making sure the Zip Code is correct?
Hello We registered on TDAC and received a document to download but no email.. what should we do?
If you used the government portal for your TDAC application, you may need to submit it again. If you applied for your TDAC via agents.co.th, you can simply log in and download your document here: https://agents.co.th/tdac-apply
May I ask, when filling in the information for the family, can we use the same email for the additional travelers? If not, what should we do if the child does not have an email? And the QR code for each passenger is not the same, right? Thank you.
Yes, you can use the same email for everyone's TDAC, or use separate emails for each person. The email will be used for logging in and receiving the TDAC only. If traveling as a family, one person can act on behalf of everyone.
Thank you very much.
How come when I submit for my TDAC it asks for my last name? I do not have any last name!!!
For the TDAC when you have no family name you just can put a dash like "-"
How to get a 90-day digital card or 180-day digital card? What is the fee if any?
What is the 90-day digital card? Do you mean e-visa?
So glad I found this page. I tried submitting my TDAC on the official site four times today, but it just wouldn’t go through. Then I used the AGENTS site and it worked instantly. It was completely free too...
If you are just transiting in Bangkok to continue your journey, then no TDAC is needed, right?
If you leave the plane, you must fill out the TDAC.
Do you really have to submit a new TDAC if you leave Thailand and for example go to Vietnam for two weeks and then return to Bangkok? Sounds complicated!!! Has anyone experienced this?
Yes, you still have to fill out the TDAC if you leave Thailand for two weeks and then return. It is required for each entry into Thailand, as the TDAC replaces the TM6 form.
After entering everything and viewing the preview, the name is incorrectly converted to kanji. Is it okay to register as it is?
Please turn off the browser's automatic translation feature when applying for the TDAC. Using automatic translation may cause issues such as your name being incorrectly converted into kanji. Instead, please use the language settings on our site and ensure that it is displayed correctly before submitting your application.
In the form it asks for where I’ve boarded the flight. If I have a flight with a lay-over, would it be preferred if I write my boarding information from my first flight or the second one which actually arrives in Thailand?
For your TDAC, use the final leg of your journey, meaning the country and flight that brings you directly into Thailand.
If I said that I’ll only be staying for a week on my TDAC, but now want to stay longer (and can't update my TDAC information since I’m already here), what do I have to do? Will there be consequences if staying longer than said on TDAC?
You don’t need to update your TDAC after entering Thailand. Just like the TM6, once you’ve entered, no further updates are required. The only requirement is that your initial information is submitted and on record at the time of entry.
How long does it take for approval for my TDAC?
TDAC approval is instant if you apply within 72 hours of your arrival. If you applied earlier than that for your TDAC using AGENTS CO., LTD., your approval is typically processed within the first 1–5 minutes of entering the 72-hour window (midnight Thailand time).
I want to buy a sim card when filling in the TDAC information, where should I pick up the sim card?

Hi…i will be travelling to malaysia first amd then my flight has a layover of 15 hours at Changi, singapore . I will be exploring the Changi airport and will be in the airport for the whole duration of the layover. While filling up the form for the arrival section ..which country do i mention for country of boarding?
If you have a separate ticket / flight number then you use the last leg for your TDAC.
Flight number is different but the PNR is same for the KUL-SIN-BKK
For your TDAC, you should enter the flight number of your final flight into Thailand, as that’s the arrival flight immigration needs to match.
If monk doesn't have family name how to submit TDAC?
For the TDAC you can put a "-" in the family name field if there is no family name.
Do I need to fill departure details on my Tdac as I will be applying for extra time in Thailand
For the TDAC you do not need to add departure details unless you will be only staying for 1 day, and do not have any accommodation.
Can I fill TDAC 3 months ahead?
Yes, you can apply for your TDAC early if you use the agents link:
https://agents.co.th/tdac-applyHello I applied for an eSIM card on this page and paid and applied for TDAC, when will I get a response to that? Best regards, Klaus Engelberg

If you need assistance, you can contact us anytime at [email protected].I had bought it earlier and it seemed to be downloaded, but now it's not there, what should I do?
Hi if I'm coming to Thailand but I'm only staying 2 or 3 days and traveling, for example, to Malaysia, then coming back to Thailand for a few days, how does it affect the TDAC?
For each international entry into Thailand, you need to complete a new TDAC. Since you're entering Thailand once before and once after visiting Malaysia, you'll need two separate TDAC applications.
If you use agents.co.th/tdac-apply, you can log in and copy your previous submission to quickly get a new TDAC issued for your second entry.
It saves you from having to re-enter all your details.Hello, I am a Myanmar passport holder. Can I apply for TDAC to enter Thailand directly from Laos port? Or do I need a visa to enter the country?
Everyone needs the TDAC, you can do it while in line. The TDAC is not a visa.
My tourist visa is still pending approval. Should I apply for TDAC before the visa is approved since my travel date is within 3 days?
You can apply early via the agents TDAC system, and update your visa number once it's approved.
How long does a TDAC card allow me to stay?
The TDAC is NOT a visa. It is just a required step for reporting your arrival. Depending on your passport country you may still need a visa, or you may qualify for a 60-day exemption (which can be extended for an additional 30 days).
How to cancel a TDAC application?
For the TDAC, it is not necessary to cancel the application. If you do not enter Thailand on the arrival date indicated in your TDAC, the application will be automatically canceled.
If you have completed all the information and confirmed it, but the email was entered incorrectly, resulting in not receiving the email, what can be done?
If you filled out the information through the website tdac.immigration.go.th (domain .go.th) and entered the email incorrectly, the system will not be able to send the documents. It is recommended to fill out the application again. But if you applied through the website agents.co.th/tdac-apply, you can contact the team at [email protected] for us to help check and resend the documents.
