TDAC Buddy

Simplify and manage your TDAC applications

What is TDAC Buddy

All foreign visitors to Thailand must submit an application for a Thailand Digital Arrival Card (TDAC) before entering the country. An online form is available, but many fields must be completed for every application.

TDAC Buddy makes multiple visits to Thailand a breeze, remembering your details on your private iCloud account so subsequent TDAC applications are a few clicks away.

The Thai Immigration authorities has more information on TDAC requirements here.

TDAC Buddy is built and designed by a frequent traveller for frequent travellers. It is not an “official” app, and is not endorsed in any way by the Thai immigration authorities. It just provides a convenient way to use their website and store your details for future trips.

The app runs on iOS (18 or later) and iPadOS (it’s best in iOS26 windowed mode). A macOS version is in the works. Sorry there is no Android, Windows or Linux version at this time.
