Will leaving the USA on the 11th and arriving in Thailand on the 14th violate the TDAC advance submission requirement?

Hello, I have a TDAC question. I will leave the USA early on 11th but not get to Thailand until the 14th.  Does this create a 3 day in advance problem? TY.

Answer summary

The question addresses concerns about the TDAC (Thailand Declaration Arrival Card) submission in relation to travel dates. Users clarified that while the TDAC must be submitted no more than three days prior to arrival, it can be completed anytime within that 72-hour window, even during layovers. Travelers are advised to submit the TDAC as soon as possible before departure or during layovers. The submission is merely informational and doesn't require prior approval.

In addition to the TDAC, you will need to show your boarding pass (flight that brought you into🇹🇭) to the IO.

So the website will only allow you to submit 3 days before your arrival date - all based on Thai Time /calendar. If it's taking you 3 days to get there and assuming your not walking you must be stopping over somewhere. If you cannot do it just before you leave do it during your stopover. Note there is no approval or non-approval it is just collecting information. It takes 5 minutes to do online. If you plane has wifi you can even do it en-route. Still today many people forget or don't know and you will see them doing it just before immigration counters on arrival.

It's within 72 hours of standing in front of immigration desk. So any time within that window, even after landing. It's same as when it was filled in, on paper, with a pen and handed to the immigration officer.

Try to do it before you leave. If you cannot select your correct date, do it in one of your layover airports using their wifi.

I’m arriving in early January so I haven’t seen the TDAC yet. Is it an electronic document that I can show on my device or is it something that I need to print and show?

it's all electronic and you get a QR code after you submit it. The passport control officer should be able to see that you completed it when they scan your passport.

99% of the time you don’t have to show it because when the immigration officer takes your passport they can see it. However if there’s an issue you may be asked to show it but on your device would be fine
