Do I still need to apply for a visa if I have the Thailand Digital Arrival Card?

The Thailand Digital Arrival Card (TDAC) will not change Thailand’s visa requirements. Therefore, if you require a visa to enter Thailand, you must still apply for the relevant visa and obtain the TDAC before your arrival to Thailand. For visa-exempt travellers, the TDAC will function as a pre-arrival registration system, similar to Electronic Travel Authorisation (ETA) documents in other countries.
