Following information found on this website might be helpful, but it did not directly provide the information I needed:

https://tdac.info/blog/how-to-fill-thailand-digital-arrival-card

What I often find extremely stressful are the small letters in forms and the additional information that must be filled in, combined with the relatively small spaces where the data has to be entered. I once traveled to Laos and confused the relatively tiny word “Place” with “Race.” I tend to read what I think I see in my mind, especially when arriving at a border crossing for the first time.

I am simply trying to reduce some of the confusion surrounding TDAC forms by showing clear practical examples of valid and invalid situations.

From the form designer’s perspective, the TDAC logic appears to assume:

  • if arrival and departure are on the same day,

  • then you are considered an in-transit or same-day traveler,

  • therefore no overnight accommodation in Thailand is required.

So the accommodation section being disabled is probably intentional behavior rather than a technical bug.

My situation is a special edge case because:

  • I am a Thailand resident,

  • I briefly leave the country,

  • then re-enter Thailand and return home the same day,

but technically my “stay” after re-entry is not a short tourist stay.

By leaving the departure date empty, the system switches back to the normal logic for travelers entering Thailand to stay in the country, which is why it allows my Thai home address to be entered again.

So my final submitted TDAC was probably the most correct interpretation for a resident returning home in Thailand.

Suppose I make a one-day trip to a cave in Laos and return home the same day. In that case, a form like this would be valid:

Actually, some transport data on this form was not entirely correct. For foreign travelers, the “BOAT” and “LOCAL FERRY” options do not necessarily match the actual border-crossing procedure at Nakhon Phanom. Foreign nationals are generally redirected to Friendship Bridge III and typically cross by vehicle instead. In practice, “CAR” and something like “VAN” would probably have been more accurate.

That is something you only discover once you arrive there.

Now an example of a form that may look reasonable but can become logically inconsistent from an immigration perspective:

Wrong TDAC-form.png

If you do not live in Thailand, then it normally makes sense to enter onward departure information, such as a departure date and flight number.

After re-entry, immigration may issue a new 90-day reporting slip, effectively restarting the 90-day reporting countdown from the new entry date. At Friendship Bridge III, this slip was only available in Thai.

If you travel with a multiple re-entry permit, immigration will normally place a new entry stamp in your passport upon re-entry, while the multiple re-entry permit itself remains valid for future trips until its expiry date.

In the TDAC visa-number field, I entered the multiple re-entry permit number from my passport. Admittedly, that handwritten number can be difficult to read because immigration officers often write it in very cramped handwriting.

No one has to enter departure information. It's an optional field. Best to just skip it to save time and prevent any mistakes. Same goes for visa number, it's optional, so skip it every time.

The immigration officers do not have access to the TDAC data. All they see is it one was filled in or not. Any inconsistent data or differences from what was entered are irrelevant.

Also borders do not issue 90 day reporting slips. A TM47 done by the foreigner after spending 90 consecutive days in Thailand. Borders have nothing to do with TM47.

You are correct about the people who incorrectly put the "departure information" as the departure from wherever they are traveling to Thailand from though. I'm not sure why people think that since it's AFTER the arrival information, but that's what causes all the complaints about not being able to put the address information.
