Starting May 1, 2025, all foreign nationals wishing to enter the Kingdom of Thailand must register electronically prior to their arrival. This new regulation applies to travelers regardless of their mode of transport—whether by air, sea, or land border. Registration must be completed no later than three days prior to entry using the Thailand Digital Arrival Card (TDAC) system.
Various information is required as part of this online registration. Travelers must provide personal information, their travel document number, details of their planned trip, the address of their accommodation in Thailand, and, if applicable, a health declaration if they have been in a country classified as a high-risk area in the two weeks prior to travel. Upon successful submission of the form, travelers will receive a confirmation email, which they can present for identification upon entry.
This new measure is being introduced by the Thai authorities to modernize entry formalities. While the original report from a Czech travel agency emphasizes the benefits for travelers due to the more convenient process and the elimination of paper forms, it is assumed that the Thai government's primary intention is to improve the registration and control of incoming travelers. It is recommended to consult the official website of the Thai Immigration Service for the TDAC system, as well as the travel advisories of the respective foreign ministry of the home country, for detailed and up-to-date information.
