Please assist.

I am trying to fill in my digital thai arrival card ( DTAC). My arrival date is 3rd May 2025, as I write the date today is 3rd April 2025. It says my arrival date is invalid. Do I have to wait until 1st May before I can apply (3 days). Is it not possible to apply before ?

TLDR : Answer Summary
You can only fill in your Thai digital arrival card (DTAC) within three days of your arrival. Since your arrival date is May 3rd, you need to wait until May 1st to fill it out. This restriction ensures that the form is completed close to the date of entry.

Does anyone have any information on what they are asking for with the medical section of the form?

@Ricky *****
probably about travelling from Africa or other known yellow fever areas. Its normal i do it often you have to report to medical booth if you coming from one of those countries show them your vaccinations and they mark your boarding pass as checked.

@Colin ******
there in lies the real question.....the official line is this....

WHEN SUBMIT?

Foreigners should submit their arrival card information 3 days in advance of arriving in Thailand, including the date of arrival.

I’ve done it the same day for Singapore and Malaysia. Takes 5mins and you get a response e mail within a few minutes so I’m guessing it will be the same
Anna *********
Yes you have to wait and no you can’t do it early.

WITHIN 3 days is the instruction 😀

3 days before and it replaces the form you used to complete on the plane, so no rush.

You will still need the DTAC from next month rep or no rep 🤔

I went to koh samui in September 24. Flew etihad, a lovely rep picked us up when we landed at Phuket and took us down the corridor to the vip and air crew immigration desk where they just stamped the passport very quickly, she then escorted us to our domestic flight to Koh Samui. I didn’t fill in any forms. This maybe because we landed within one hour of our domestic flight. They were fantastic, super efficient.

@Nick *******
no it’s because it doesn’t start until May 1st 2025

Very good question because I am leaving on the 30th April and I will be in Bangkok on the 1st of May
John ********
I was going to do it on 29th and see what happens, but I don't trust the thai immigration
Wayne *********
@John *******

that's interesting. But it starts on 1st of May and info says apply up to 3 days before so try day before.
