Thailand’s Immigration Bureau has warned foreign travellers about fraudulent websites offering Thailand Digital Arrival Card (TDAC) services for a fee, stating that the process is mandatory but free and must be completed only through official channels. The alert has been issued through the bureau’s official website as part of efforts to prevent scams.

The TDAC system, introduced on May 1 last year, replaced the TM.6 paper form and requires all foreign visitors to submit their arrival details online before entering the country. Authorities said travellers must register through the official TDAC portal or via the Immigration Bureau’s main website, which provides a verified link and QR code.

Misuse of unofficial platforms flagged

Officials also warned that personal information submitted on such websites could be misused, exposing travellers to scams or identity theft. Some platforms collect data under the pretext of providing e-visa services.

Travellers have been advised to complete TDAC registration at least three days before arrival to allow processing and confirmation via email, which can help reduce waiting time at immigration counters.

The Immigration Bureau said it is working with other agencies to identify and shut down fraudulent websites, though enforcement remains challenging as many of these platforms are hosted outside Thailand.

Authorities have also asked airlines to inform passengers to use only official channels for registration before travel to avoid delays and unnecessary costs.
