ORIGINAL POSTER
I am attempting to get my TDAC online, arriving in Thailand on Thursday 1st May, 13 days ahead, the system will not allow me to input arrival date beyond 20 April.

I understood that application had to be made more than 3 days before arrival.

Have I got this wrong.

It seems that you can't apply that far ahead

Thanks for any advice.

TLDR : Answer Summary
The TDAC (Thailand Digital Arrival Card) application must be completed within 3 days prior to your arrival date. The system will not accept applications submitted more than 3 days in advance, hence the user attempted to enter an arrival date beyond the allowed period. Many comments supported this rule, advising that users should wait until closer to their travel date, specifically after April 28, to apply. The conversation also highlighted potential challenges with the system's rollout and the anticipated influx of travelers needing assistance when the process begins.

3days out only
Anna *********
@Bob *********
no Within 3 days so it could be 1 or 2 days or 4 hours out
Bob **********
@Anna ********
yes start 3 days out and if you haven’t got a smartphone of lap top they’ll assist you on arrival
Anna *********
@Bob *********
your reply makes even less sense Why would you assume I or anyone would need help 🤣🤣🤣
Bob **********
@Anna ********
there are a lot of people that are not IT friendly so they will file the TDAC for you,in your case you have a plate of desert as your profile so indeed you need help
Anna *********
@Bob *********
you are very odd What difference does my profile pic make to anything Fancy even looking
Richie *******
Jeez don't people read the posts or even look into what the requirements are
John **********
Can you see this working thousands of travellers will be filling this on line myself included. What happens if you don't get the arrival card in time
John *********
I'm sure there will be the usual chaos on May 1 🤣
Jay *******
@John ********
requiring it be done "within" 3 days of travel almost guarantees it.
Nick ************
It's like when it says press the green button to start and you wonder why nothing happens when you press the red button.
Peter **********
@Nick ***********
… and then press the red button a few times more to test whether the computer changed its mind… 🤣
Stephen ***********
It doesn't start up until May 1
Robert ******
Can anybody read simple instructions I am amazed how some people manage to get dressed by themselves nowadays 😂

@Robert *****
It's because of these folks that there are instructions on shampoo bottles.
Paul ******
Only 3 days before you travel no earlier
Luc ************
Another one.
Jo **********
why ?
Francois ********
In the events of TDAC system errors,no Wi-Fi, passengers with technology issues/no smart fones, etc.

Will AoT provide TDAC kios and/or officers to assist passengers to complete TDAC process?
Henry *********
@Francois *******
Yes. I suspect it will be busy!
Kenneth *******
@Francois *******
I think 🤔 if you don't no how or you don't have a friend or family member to fill in the form there is help at the airport but I'd say 1hr to do it .

i misread the post, thinking it had to be done earlier than 3 days to give immigration time to process it.

I guess as soon as you have submitted the TDAC form, you will receive an instant email confirmation. The TDAC forms will not be checked or cross examined by anyone
Tony ***********
I have had the same problem won't let you put arrival date in June saying wrong info. So it looks like you will have to wait until 3 days prior to departure and hopefully nothing goes wrong.
Anna *********
@Tony **********
what on earth could go wrong 😳
Phil *******
@Tony **********
yes that's what it says.
Martyn ***********
There's going to dozens and dozens of these.. 2nd one I've seen in 5 mins.
Shawn *******
@Martyn **********
I'm a 66 year old female senior. Do you think that I understand the Thai visa .I'm not good with computers so now I'm looking for someone to help me fill it out. It's very confusing.
Peter **********
@Shawn ******
It’s not even a visa. It’s an arrival card. Countries created this so the personal information is already in the system so the immigration officer doesn’t have to do it.

Shortening the queues.
Martyn ***********
@Shawn ******
Why are you telling me? There will dozens like this and with all due respect.. People like yourself are one of the many reasons.
Baz *********
WITHIN 3 days..

Not before
Lynnette *******
It doesn't say before 3 days. It says "within" 3 days. Within=inside of. So from day 3 to zero.
Brandon ************
You do have it wrong, almost exactly wrong. It CANNOT be more than 3 days before arrival. You can only choose an arrival date 0-72 hours away. So you fill it in when you are 3 days or less from arriving.

@Brandon ***********
l was about to ask similar question but you answered my question, l leave London 9th June Arrive Thailand 10th June 3pm local time.
Wayne ********
@Abey ********
I would just apply just before you go to the airport. The airline may request the QR code to allow you to board your flight.
Peter **********
@Wayne *******
Why would that be? You can still enter without a tdac after 30 April, but you may expect a long queue. 😉

@Brandon ***********
