If we're talking about the same thing, then yes! Just to clarify: with a DTV, you need to do the 90-day report in person more than once over 5 years (even if you extend your stay in Thailand). But if you do border runs, then you have to report in person every time you re-enter.
You can do it online only if you haven’t left Thailand yet. The first 90-day report after re-entry must always be done in person. Online reporting is usually possible only if you’ve extended your DTV while staying in Thailand.
