Starting 1 May 2025, all non-Thai nationals entering Thailand by air, land, or sea must complete the Thailand Digital Arrival Card (TDAC) online within three days before arrival. Completion of the TDAC will be mandatory for all foreign passport holders, including tourists, business travellers, 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 may submit the TDAC up to three days before their scheduled arrival date. For example, if arriving on 5 May, submission can begin on 2 May. The system will open for submissions starting 28 April to accommodate those arriving on the launch date.

Travellers can submit the TDAC individually or as part of a group via the portal. Information can be updated at any time before travel. Required details include passport information, personal and travel details, accommodation in Thailand, and a basic health declaration. Long-term or permanent foreign residents in Thailand are advised to select “Thailand” under “Country of Residence,” which will be available once the system is activated.

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.

Travellers are encouraged to review the official guidance and complete their TDAC well in advance of their journey to ensure a smooth arrival in Thailand.
