The Official Entry Requirement: The TDAC
As of 2026, all foreign travelers entering Thailand are required to complete the Thailand Digital Arrival Card, or TDAC. This online form replaced the old paper-based TM.6 arrival card and is a mandatory step for immigration screening. The key thing to know
is that submitting the TDAC is completely free of charge. It is not a visa, but a required entry document for everyone, including those entering under visa exemption rules. You should complete the TDAC via the official government portal within the 72 hours before your arrival. Thai authorities implemented this digital system to streamline the entry process, making it faster and more secure for visitors.
The Rise of Unofficial 'Service' Websites
Dozens of unofficial third-party websites have emerged, hoping to profit from travelers' confusion. These sites often look professional and may even appear at the top of search engine results, sometimes through paid ads. They offer to process your TDAC for a fee, which can range anywhere from USD $10 to as high as $90. These platforms lure travelers by offering supposed 'assistance', 'expert review', or 'simplified forms'. However, they are simply charging for a process that is designed to be simple and free on the official government website. Thai immigration authorities have repeatedly issued warnings about these fraudulent sites, noting that a surprising number of travelers, perhaps as many as 10 percent, fall victim to them.
Risks Go Beyond Unnecessary Fees
The financial loss is frustrating, but the risks of using these unauthorized platforms are more significant. When you enter your details on a non-government website, you are handing over sensitive personal information, including your full name, passport number, and travel itinerary, to an unknown entity. This creates a serious risk of data misuse, scams, and even identity theft. Furthermore, there is no guarantee that these third-party agents will submit your information correctly or on time. An improperly filed application could lead to significant delays and questioning upon your arrival at immigration, defeating the very purpose of pre-registering.
How to Identify an Unofficial Website
Spotting a fake or third-party website is straightforward if you know what to look for. The single most important clue is the URL. Official Thai government websites always end with the domain '.go.th'. The official TDAC portal is tdac.immigration.go.th. Any website with a different ending, such as .com, .org, or .info, is not the official government channel. Another major red flag is any request for payment. If a website asks for a 'service fee', 'processing charge', or any other form of payment for the standard TDAC, it is not legitimate. These sites may have disclaimers in small print stating they are not affiliated with the government, but their primary design is to mislead you.
Your Guide to a Smooth Arrival
To ensure your entry into Thailand is hassle-free, always use the official channel. Navigate directly to the official Thailand Immigration Bureau website to find the verified link and QR code for the TDAC platform. Have your passport, flight information, and the address of your accommodation in Thailand ready before you begin. The process only takes a few minutes. You will fill in your personal and travel details, review them for accuracy, and submit the form. After submission, you should receive a confirmation with a QR code by email, which you can show to the immigration officer on your phone or as a printout upon arrival. Remember to complete this step for every person in your travel group and for every new entry into the country.
