Guys what happens if you arrive without TDAC?

I’ve refreshed and atarted over 4 times & still this date error, won’t let me go to the next page
Answer summary
If you arrive in Thailand without completing the TDAC (Thailand Digital Arrival Card), you can fill it out upon arrival at designated kiosks at the airport. It's advisable to do this before going to immigration to avoid delays. The departure date is not mandatory; many users noted that it's often left blank without issues. The TDAC can only be completed starting 72 hours before your intended arrival date, so ensure you're within that timeframe. If you face technical difficulties while filling it out, using the calendar tool is recommended to avoid format errors.

The new system has facial recon as you pass through, this will immediatly flag if you havent completed the on line arrival card.

This once tourists realize this mean if completed you will be able to walk straight through.

For a un- known period yes you can complete it on arrival, however this is not a long term option or their isnt any point in it.

When you come up the ramp, on the far left of it there is a section taped off that you follow and then you sit behind screens with someone to help you fill it out, I went in December and lots of Brits didn't have it filled out as weren't aware of it so I saw them come out the que and go over to the left side,

Select the date from the calendar dropdown icon. Because you are typing it in the format is being registered in the box as text rather than a date selection its a bug in their code. It should have a placeholder message saying click calendar icon to select date and a restriction measure to stop you selecting the box to type in it

Departure card (TDAC) is a digital version of what you used to fill in on the plane - you can't fill it in until about 3 days before you arrive.

it is FREE - if someone wants your money IT IS A SCAM!

On arrival you will see TDAC stations where you can fill in your form before immigration and passport control.

Don't queue for passport control until you've filled it in.

For every entry into Thailand, non-Thai citizens are required to have completed the TDAC, regardless of whether they have a visa or an existing stay permit.

The TDAC is not a visa. The electronic TDAC is just replacing the former TM6 arrival & departure paper card you used to fill out aboard your flight before you entered Thailand.

You can fill out and submit the TDAC (Thailand Digital Arrival Card) starting three days/72 hours before your planned entry; it only takes five minutes on your home computer, it takes a little bit longer on the smartphone

It's important not to fall for fraudulent websites that charge a fee for the TDAC—they're all scammers. The official TDAC is free of charge. The correct ending of the link has to be “go” and “th”

Open the official website and simply fill it out pro forma.

Create a note or a Word .doc document on your computer with the requested information, e.g., passport number, name and address in your home country, primary address in Thailand, and so on.

Then, starting up from three days/72 hours before your planned entry, you can copy and paste the information into the TDAC—it only takes two minutes!

NOTE: The "Visa Number" and "Departure" from Thailand are NOT mandatory required fields- you can leave them blank.

BUT: As soon as you click on one of these fields not marked with a red *asterisk or start typing, an error message will appear if you don't fill out anything else. Then you would have to cancel everything and start over.

The TDAC confirmation will reach your email inbox shortly after you have submitted the form. You should print out this email confirmation, as it contains a QR-code. Mainly expats who apply every year for their annual “extension of stay permit”, should print it out, because a printed and signed copy of the TDAC could be a part of the document submission on Immigration

If you don't have to present the printed TDAC at the immigration counter, it doesn't mean anything - the border official will see the TDAC you submitted on his/her computer screen as soon as they scan your passport, so they won't ask again

The TDAC is not a visa, it is only an information you give Thai authorities about your person, your arrival information and your place of stay.

Assuming you haven't completed a TDAC, they won't let you enter the country but will send you back to the terminals in front of the Immigration desks with a request to submit it.

There are machines just before immigration where you can file the TDAC. There’s a helper there if you need any assistance.
