How to complete it
The official government form is available online, but travelers sometimes run into slow load times, confusing captcha errors, or vague error messages. iVisa is a private travel-document service, not a government body, and offers optional help completing the TDAC through its web platform or mobile app for a service fee; see the iVisa Thailand Digital Arrival Card service for details. There is no government fee for the TDAC itself.
If you prefer to do it yourself, you can use the official Thai government portal directly at no cost.
