Applicable Persons, Submission Time, and Submission Method for TDAC

Below are explanations regarding the applicable persons, submission time, and submission method for the TDAC.

1. Who needs to submit the TDAC?

The “Thailand Digital Arrival Card” applies to all foreign travelers entering Thailand, including tourists and business visitors for short-term stays. However, transit passengers who do not enter Thailand are exempt from filling it out.

2. When can the TDAC be submitted earliest?

The TDAC is valid for 3 days (72 hours), so the system only allows submissions within 3 days before the arrival date. For example, if arriving on May 30, the earliest submission date is May 27. To avoid delays due to flight changes or customs queues, it is recommended to submit the TDAC no earlier than 60 hours before the scheduled arrival time.

3. Where can the TDAC be filled out and submitted?

The “Thailand Digital Arrival Card” can only be filled out and submitted through the official website of the Thailand Immigration Bureau (https://tdac.immigration.go.th/arrival-card/#/home). There is no mobile app. The website supports five languages: English, Chinese (Simplified), Japanese, Korean, and Russian.

Different languages can be switched by clicking the language menu in the top-right corner of the webpage.
