What should I do if I encounter an 'invalid data error' on the TDAC website while using a retirement VISA in Thailand?

THIM and TDAC notice
Need a clearer THIM and TDAC explanation? Read the THIM guide on thim.in.th.

Hi group has anyone else been having problems with the TDAC website the last 2 days? I keep getting an "invalid data error" when I select Thailand as my country of residence (I'm on a retirement VISA). I haven't been able to find assistance for this problem & I'm due to fly in a few hours now..
Answer summary
A user is experiencing an 'invalid data error' on the TDAC website when entering Thailand as their country of residence while on a retirement visa. Community members suggest using the passport country instead of Thailand, as well as confirming that they are on the official website. Others share similar experiences and recommend trying different devices or browsers. Ultimately, the user found success by calling immigration, who advised them to fill out the information at the airport kiosk upon arrival.

Deslea Selmes if you are on a DTV by definition you are a tourist not a resident

Vinson Dynes I’m not on DTV myself, but the TDAC doesn’t ask your visa class, so I don’t think that’s why the original poster is having trouble validating - there’s nothing to cross reference it against. It does have a field for visa number but it‘s optional and not dynamic.

James Anderson never forget, you are not a resident in Thailand, you are just a guest. Your stay permit is always only temporary

Greg Alexander yeah I do understand this, it's just a change in their system as previously it worked with this. I have no residence in my home country as haven't lived there for + 6 years now 😄

James Anderson I got the same message over and over. So I ended up using my home country as the residence
