What should I do if I encounter errors while trying to submit my 90-day report online in Thailand?

If the 90 day online report system does not work, AND you’re between the due date and 15 days prior to the due date, AND you already filed one 90 day report in person, there are some troubleshooting techniques you can use to try and get the system to work for you.

1. Make sure you’re filling in the information, and only the information, requested.

2. Make sure you are keying in the date and month correctly

3. Turn off any pop-up blockers

4. Turn off any auto-translate

5. Turn off any VPNs (Virtual Private Networks) that you may be using - including any data saving applications

6. If you’re using one of the applications, use the web-based system

7. If you’re using the web based system, try using a different browser and clear the cache.

8. Make sure your web browser isn’t automatically filling in the forms.

9. Make sure you aren’t confusing “O”(Oh) with “0” (zero)

10. If you’re keying your date manually, try using the drop-down date selection box

If the system still doesn’t work, then you may need to file it in person.

There was a post earlier today that the system wasn't working correctly for some reason, it could be related to that.

Same happened to me and at least one other in another post today.

Coincidentally we both went in person to report today, Bangkok.

Same happened to me. Been doing it online for years then BOOM it stops working. No info whatsoever has changed. Tried 3 different browsers but still doesn't work. I've asked them but, of course, I get a blank stare.

I would say, if you get the pop up again to contact Immigration, go there and ask the check all data and what possible goes wrong between your computer and theirs.
