Thailand Digital Arrival Card (TDAC) Requirements

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).

You can download the eSIM after submitting your TDAC at agents.co.th/tdac-apply

If there are any issues, please email: [email protected]

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.

For the TDAC you can put a "-" in the family name field if there is no family name.

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.

Yes, you can apply for your TDAC early if you use the agents link:
https://agents.co.th/tdac-apply

If you have purchased an eSIM, a download button should be visible immediately after purchase. You can download the eSIM right away.

Your TDAC will be automatically sent to you by email at midnight, exactly 72 hours before your arrival date.

If you need assistance, you can contact us anytime at [email protected].

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.

Everyone needs the TDAC, you can do it while in line.

The TDAC is not a visa.

You can apply early via the agents TDAC system, and update your visa number once it's approved.

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).

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 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.

If traveling to the country by bus, please specify the bus number in the TDAC form, you can enter the full bus number or just the numeric part.

For both the official TDAC and the agents TDAC, the additional travelers option comes after you submit your first traveler.

With a group that large, you may want to try the agents form just in case anything goes wrong.

Sometimes the Cloudflare check just doesn’t work. I had a layover in China and couldn’t get it to load no matter what.

Thankfully, the agent’s TDAC system doesn’t use that annoying barrier. It worked smoothly for me without any issues.

If you used the Agents TDAC, you can just log in and edit your TDAC, and it will reissue for you.

But if you used the official government form, you will have to submit the whole thing again as they do not allow editing the passport number.

You cannot update your departure details on the TDAC after you’ve already arrived.

Currently, there's no requirement to keep the TDAC information updated after entry (just like the old paper form).

I have also contacted via email and Line, just awaiting feedback, but I am unsure what’s going on.

You can always contact [email protected]

It sounds like you made a typo in your email for your TDAC.

For Thai eSIM cards, you must be in Thailand to activate them, and the process occurs while connected to a Wi-Fi network.

You’ll need to apply for two TDACs.

With the TDAC agents system, you can first complete one application, then log out and log back in.

You’ll then see an option to copy your existing TDAC, making the second application much faster.

Yes, I used that one to apply for my 2026 trips TDAC.

Hello. Myanmar crew members need a Transit Visa to board in Bangkok. The fee is US$35.

This matter is not related to TDAC (Thailand Digital Arrival Card). TDAC is not required for crew members.

When I selected a city with a "-"

If you submit with an agent, then you can submit up to a year in advance.

thx

Just put the numeric part for the TDAC if it does not allow you to.

Found it, thanks. :)

The official TDAC form has a bug right now where if you select a city with a "-"

In your situation, your second flight likely has a different flight number. Because of this, you will need to select China and the corresponding flight number for your TDAC as the country of departure.

For TDAC, if you are Thai but enter the country using a UK passport, you will need to fill out TDAC for the same reason you will receive a visa stamp.

Just select the UK as the country in your passport.

If it's a separate ticket, then you should be using the last ticket/leg of the journey for your TDAC arrival flight.

Yes, you must submit a TDAC application for each entry into Thailand.

The earliest you can do this via the official government website (https://tdac.immigration.go.th/

You do not need to update your TDAC as you have already entered Thailand.

It is fine if there are repeated names of areas or sub-areas in the hotel address. As long as the complete address and postal code are correct and consistent with the actual location of the hotel, it will not cause any issues with the TDAC application.
