Thailand and TDAC: How does it work?

You're splitting hairs

72 hours = 24 hours x 3 days (same difference)

No, it's not the same thing. For example, if you plan to arrive on the 5th at 1 PM, "3 days before" would mean you can fill out the TDAC all day on the 2nd, whereas "72 hours before" means you can only fill it out starting at 1 PM on the 2nd for it to be valid.

The Thai Embassy clearly states in red "within 72 hours before entering Thailand." http://www.thaiembassy.fr/fr/visa-rdv/infos-generales/thailand-digital-arrival-card-tdac/

Hi, I did a simulation of the TDAC with my details. When you get to the arrival date section, a table opens where you can indicate your arrival day. However, only 3 days are available. For example: I fill out my TDAC on August 6th, I can indicate my arrival day up to August 9th, but not beyond.

Exactly, the Thai Embassy in Paris states it must be done 72 hours before arrival.

Assumption: A flight from CDG lands at 9:00 AM on Thursday, September 18, 2025, in BKK (3:00 AM Paris time). So, following the logic, You can fill out your TDAC starting from Monday, September 15, 2025, at 4:00 AM (Paris time).

To avoid any complications, I suggest doing it 2 days before or within the 48 hours prior.

Hi, If they say 72 hours before or 3 days, know there are reasons for it. For the 48 hours before, it depends on what time your flight to Thailand departs. Don’t forget that airlines may ask you to show proof of the TDCA procedure. For example: AIRFRANCE, EMIRATES, THAIAIRWAYS

Gosh, you’re all scaring me with this new form I’ll do it 48 hours before, hoping I fill out the right form..., on the right site..., and don’t get any nasty surprises on arrival...

Hi, You can do it 3 days before (72 hours). Example: You arrive on Saturday, September 13, 2025. You can complete the TDAC online On Wednesday, September 10, 2025.

Nothing complicated. And the boxes without a red star are optional.

Thanks to both of you for your replies. And to know which site to go to, I guess I can find the info on the embassy’s website? My last trip was at the end of 2023—it wasn’t in effect yet

One per person, of course. It's free, so watch out for pirate sites that charge you.

Awesome! Thanks a lot!

Hi there, You can add one or more passengers. After the health section and before finalizing, you click on "another passenger" and repeat the process for as many other people as needed.
EA Earthquake Veteran ·
OK, I didn’t know that.

OK, I didn't know.

Yes, to complete the information:

After filling out the Health section and before finalizing the file, you need to click the **ADD OTHER TRAVELERS** button, and then you start the process again to add a passenger.

Got it, thanks so much!

Hi there, Just a little heads-up: For those flying to Thailand with Air France, In the three days before arrival, They ask you to send them a copy of the TDAC per passenger as an attachment. This is to avoid having to present it during check-in and to prevent long waits. There’s a risk of not being allowed to board for those who don’t have a TDAC.

Hi there,

I came across this discussion. Having traveled to Thailand many times over the years—often staying for several weeks or even 2 to 3 months—I tend to get a bit complacent about the formalities I know. But here’s the thing: in Thailand, the rules change quite often, a bit too much if you ask me! I’m aware of the DTAC (I’ve done it twice already this year!), but now I have a question that doesn’t seem to have been covered here:

- Is there a limit to the number of entries allowed in a year in Thailand by air, under the visa exemption scheme (which allows a 60-day stay)? From what I remember—and as far as I know—there’s no limit as long as it’s by air.

I’m asking because the last time I went through immigration at BKK, the officer (who was otherwise lovely) told me, “2 or 3 times max, otherwise get a visa”—which really surprised me!

Hi there, I've been an expat in Bangkok since 2021 and fill out the TDAC regularly. Here’s how it works in practice.

What is the TDAC: It’s the digital arrival form that replaced the old paper TM6 form. It’s mandatory for all travelers entering Thailand since 2025. You fill it out online BEFORE your arrival.

How to fill it out: - Go to the official website tdac.immigration.go.th - Create an account with your email - Fill in your personal details (passport, flight, accommodation in Thailand) - Submit at least 72 hours before your flight (recommended, even though technically you can do it later) - You’ll receive a QR code by email — that’s your golden ticket at immigration

Common pitfalls: - It can be buggy on mobile, so do it on a computer instead - The hotel address must match your first night — you don’t need to list your entire stay - If you’re transiting (e.g., a layover in Singapore), you must indicate the airport of arrival IN THAILAND - The site can be slow during peak hours — don’t leave it until the day before your departure

Upon arrival: Show your QR code (on your phone or printed) to the immigration officer. It’s much faster than the old paper system. Last time at Suvarnabhumi, I cleared immigration in 10 minutes on a Sunday evening.

It’s really not complicated — 10 minutes online and you’re done. The key is not to forget to do it before your departure.
