TDAC confirmation email not received: what to do

Checked 5 November 2026 by Darius Cheung. Independent guide, not a government website.

Short answer

Check your spam folder first, and look for a typo in the address you entered. The email is only a second copy: the submitted page also offers a download, so save that if it's still open. If you have neither at the airport, the Royal Thai Embassy says to tell the immigration officer at the checkpoint.

First, did the submission go through?

A finished TDAC ends on a page marked "Submitted" with a "TH Digital Arrival Card No." It also says: "This acknowledgement message will also be sent to the email address you have provided. You may choose to download or print a copy of this for the duration of your stay in Thailand."

If you saw that page, your card was filed and the problem is only the email. If the page ended on an error or never moved on, you may not have a card at all. Go to the error guide.

Finding the email

  1. Search your spam and promotions folders for "arrival card" and "immigration".
  2. Check how you typed the address. One typo sends it elsewhere. If the page with your entries is still open, look at it there.
  3. Give it a little while, especially if the system was busy when you filed.
  4. Check it wasn't a long address. The email box takes up to 50 characters and only one address. The form should catch these, but it's quick to rule out.

If the submitted page is still open

Download the card now. The site asks whether to download the document or open it in a new tab. Save it on your phone and take a screenshot too, in case you land without data. The embassy says the PDF can be printed or shown on a smart device at immigration.

If you closed the page and have no email

The site has an update section, reached from its home page, that searches for an existing card. Its code includes a route for searching by email, and the normal search asks for your card number. We haven't run this on a real card, because we don't submit test data to government forms, so we can't say how well it works for a lost confirmation.

Filing again is also possible, as long as you're in the three-day window and your details are correct. It's free on the official site, though we don't know how immigration treats two cards for one trip, so keep the latest one and be ready to explain. Don't pay anyone to retrieve it.

At the airport

The embassy's answer is straightforward: if you do not receive the email or QR code, notify the immigration officer at the checkpoint. Keep your flight and hotel details handy. There are also kiosks at BKK, DMK, HKT, CNX and HDY if you have to file there.

For next time

Use an email you can open on your phone abroad, rather than a work account that needs a VPN. If you're filing for a family, every traveller is on one submission, so one good address is enough.

Questions people ask

How long does the TDAC email take?

Often a few minutes, according to travellers and guides. We have no official figure. A busy system could take longer.

Do I have to print the TDAC?

The embassy says the PDF can be printed or shown on a smart device, so a phone copy is accepted.

Is the email from a real government address?

We can't list the sender here with confidence, so check the link you used was tdac.immigration.go.th. Be wary of an email asking you to pay or log in.

ArrivalFiller remembers the email you used for each traveller and fills it on the last page, which removes one chance of a typo sending your card elsewhere.

Where this comes from

Rules change, so check the official site before you travel. Where we quote a form's message, we copied it from the form's own public code. Some messages may rarely appear, and we don't run test submissions on government forms.
