What should I do if I need to fill out the TDAC before arriving in Thailand with less than 3 days notice?

Need a clearer THIM and TDAC explanation? Read the THIM guide on thim.in.th.

Hi guys, i fly in 2 days and just See TDAC need 3 days ahead to be filled out. What to Do now?
Answer summary
The TDAC form can be filled out within 72 hours before your arrival in Thailand. If you're flying in 2 days, you're within the acceptable timeframe. You can complete the form at kiosks before immigration at the airport or during your time in the immigration queue. Don't worry if you're unsure; others have successfully filled it out at the airport.

Within 3 days of arrival. Not more than 3 days before arrival.

You can do it in the airport when you arrive or in the immigration queue.

TDAC can be filled from 72 hours before you arrive, until you pass the machines in the Thailand airports that let you do it there.

DTAC is a mobile phone service operator.

You fill it out here at the official source

Bad idea, may have to wait up to an hour without TDAC,

Og go thru in 10 minutes with printed QR

You can even be stopped from flying if you don’t have it at check in.

And the Thai rules say you have to do it before you travel.

it can be done ON the day of your arrival. It has to be done within 3 days of arrival, not 3 days before.

@Hen***
why on earth would they stop you from flying in when they have the facilities at the airport to do so as you land? Not a lot of sense in any of your comments, are you new to Thai? You could stop reading AI prompted answers to your reseach and focus more on understanding and experiencing what actually goes on 🤷‍♂️

It’s the group administration and Facebook, who assigns that.

Because if you get denied at Immigration, the airline are responsible for removing you from Thailand, and they may not have free seats on their flights out, and then they have to pay a hefty fine.

That’s why some Airlines will deny you to check-in if you can’t show TDAC at check-in.

That is my real life experience from entry last week.

And from visiting 10+ airline booking websites/ apps, in the week before.

I talk about my experiences entering Thailand with / without TDAC last week.

So no need to repete to me, how it is done. Adress that to the OP.

I, with a printed QR code and passport in hand, was waved through Immigration in 10 minutes, where as the person sitting next to on the plane, ended up i 3 long queues, ending taking an hour, because didn’t do TDAC before arriving in Thailand.

we are talking about the TDAC. you can do it within 3 days of arrival. you can even do it inside the airport in thailand. filling it out barely takes 5 mins. you get the approval mail within seconds. no you dont need a printout. the officer usually does not even want to see it as its in the system and linked with your biodata anyway… no you dont get denied if you not have it. airport has a separate queue for people without it. they additionally have TDAC terminals.

how hard can it be to fill out the TDAC before you go? 🤣
