I’m coming to thailand from the uk on 26th October for 90 days , I see I have to go online to fill in I assume a questionnaire so that my arrival will be a straight forward process, I see it has to be done within 72 hours of arrival , I’ve never done it this way in the past , it is a straight forward online form to fill in & do I need to download a copy or is it automatically sent to the airport awaiting my arrival electronically, thank you for your time and patience
Answer summary
When arriving in Thailand, you need to complete an online form known as the TDAC within 72 hours of your arrival. This form is straightforward and linked to your passport for immigration purposes, meaning you do not need to print it out. After filling it out online, it is processed electronically, so immigration will have your information when you arrive. You will still go through the usual immigration procedures upon your arrival.

If you click onto the site it's free and straight forward why do so many ask dum questions before trying it

Another crap reply. The guy is not sure, that's why he's asked. If you can't post positive answers best not post at all, best to stay off the site.

Ya, but Kenneth, you said its a dumb question and the guy wouldn't ask it if it was dumb. Its not dumb to him. Trouble is when people get a negative answer to a question it puts them off from asking again next time their stuck. Ok point taken!

In the past you filled in an arrival card, usually given to you on the plane, before landing... Well it's gone digital... Same info, no pen

Its just an online arrival form, you still go up to the immigration booth for fingerprints and passport stamping and potential questioning.

TDAC takes a few minutes online but must be done within three days of departure date. Very simple, don’t stress!

within 3 days of ARRIVAL date. I was so excited and tried to do it 3 days before I left US only to discover that due to the 24-hour long trip, that your advice is wrong.

I flew here departing LHR on 20th August and completed my TDAC on 17th August. I arrived in BKK on 21st August so think you are the one who is confused 😂😂

@Liam *******
nope not confused. I left Us on 29 May and applied on 27 May. It was denied since my flight did not arrive in BKK until 31 May. Your flight took half the time.

Forgot to say: doing it online using a phone was a pain and so much easier on a lap top.

You only get 60 days on arrival then have to got to immigration to get 30 day extension to stay 90days

Hi Ian, is the extra 30 day immigration visit something you do at the airport on arrival or at a different place/time later? Thx

Easy to fill in. Couldn't be more straight forward

Once you have submitted it, it should be linked with your passport. They will see it when they scan your passport at immigration, nothing further for you to do.

thank you , the online form is a straight forward process ?

@Jeffrey ******
Yes. Just be careful to ignore anything without the red asterisk, as without that it's not required and you can ignore it. But as soon as you click on it, it will become required.
