Starting May 1, 2025, all non-Thai nationals entering Thailand by air, land, or sea will be required to complete the Thailand Digital Arrival Card (TDAC) online before arrival.
All foreign visitors must submit their arrival details online before entering Thailand. Travellers may submit the TDAC three days before their scheduled arrival date.
Completion of the TDAC will be mandatory for all foreign passport holders, including tourists, business travelers, and long-term residents. Exceptions apply only to travellers transiting or transferring through Thailand without passing through immigration control and to those entering using a Border Pass.

Travellers who are unable to complete the TDAC before arrival and do not have internet access at the point of entry will be assisted at designated help points located at immigration checkpoints. This assistance is intended for exceptional circumstances only. All travellers are strongly encouraged to complete the TDAC online in advance to avoid delays and reduce congestion at entry points.
