Goodbye Paper, Hello Digital
For decades, travellers to Thailand were familiar with the TM6, a paper arrival and departure card handed out on the plane. This form has now been completely phased out. In its place is a mandatory electronic system called the Thailand Digital Arrival
Card, or TDAC. This change, implemented to streamline immigration and enhance security, affects every foreign national entering the country, regardless of their visa type. The transition from paper to a digital record means that your entry information is processed before you even reach the immigration counter, promising a much faster experience for prepared travellers. However, those unaware of the new process risk getting stuck in queues or being pulled aside, defeating the system's purpose.
Decoding the Digital Arrival Card (TDAC)
The TDAC is not a visa; it is a compulsory declaration of your arrival details. Every non-Thai national, including tourists, business travellers, and even those with long-term visas, must complete a TDAC for every single entry into the country. The form collects the same basic information as the old TM6 card: passport details, flight number, and your address in Thailand. Starting in August 2026, the Thailand Immigration Management (THIM) mobile app will become a mandatory way to submit this information, integrating the TDAC into a broader platform. Until then, both the official TDAC web portal and the THIM app are accepted methods for submission. The key takeaway is that this is not an optional step; it is a fundamental requirement for entry.
A Step-by-Step Guide to a Smooth Arrival
Completing the TDAC is straightforward if you follow the correct procedure. First, locate the official portal at tdac.immigration.go.th — be wary of third-party sites that may charge a fee, as the official TDAC is free. You must submit the form within 72 hours (3 days) before your scheduled arrival in Thailand. Submitting it earlier will result in the system holding it until the 72-hour window opens. You will need to accurately enter your personal information, passport data, flight details, and the full address of your first night's accommodation. Once submitted, you will receive a QR code. It is crucial to save a screenshot of this code on your phone or have a printed copy ready to present to the immigration officer.
Common Mistakes That Cause Delays
The most common cause of delay at border control is failing to complete the TDAC in advance. While some airports may have self-service kiosks as a last resort, using them will significantly slow you down. Another frequent error is making typos in critical information like your name or passport number. If details on the TDAC do not exactly match your passport, you may be required to submit a new form, leading to unnecessary waiting. Also, ensure all your other documents are in order. Immigration officers may still ask to see your confirmed return ticket, hotel bookings, and, in some cases, proof of sufficient funds (around 20,000 THB in cash). Having these ready, along with your TDAC QR code, is the surest way to a hassle-free entry.
