How to Identify the Official Thailand Digital Arrival Card Website
The official Thailand Digital Arrival Card website is tdac.immigration.go.th. It is operated by Thailand's Immigration Bureau and the official submission is free. Other websites may offer optional paid assistance, but they should identify themselves as independent services. For the whole process from start to finish, see the Thailand Digital Arrival Card guide.

Choose the filing route that suits you
The official address
Use https://tdac.immigration.go.th. The address in your browser must be exactly tdac.immigration.go.th. A logo, the word Thailand, or a .com domain does not make a website official. Check the address again after any redirect, before you enter passport details or pay any website.
Official portal and assisted services
The official portal is free. It lets you file for up to 10 travellers in one submission, gives each traveller their own TDAC with a QR code to download, and also sends it by email. Before you travel, you can change most details with Update Arrival Card. Full name, passport number, nationality and date of birth cannot be changed there; if one of them is wrong, submit a new card. The latest submission is the one used.
An independent service charges for its own work, such as guidance, review, support or document handling. It does not charge a government fee, because there is none.
How to check that you are on the official site
Read the address
The address bar must show exactly tdac.immigration.go.th. Extra words, extra letters or a different ending, such as .com, mean it is a different website.
Look for https, but do not stop there
The address should start with https, and your browser should show no warning. Many copycat sites also use https, so https alone does not prove that a site is official.
Type the address yourself
Type it into your browser, or use a link from an official Thai government page, such as the Immigration Bureau or the Tourism Authority of Thailand. Be careful with search results marked as ads: they can be paid services or copycat sites.
Check whether it asks for money
The official TDAC is free, and the official form does not ask for payment. A site that asks for a fee is not the government portal, however official it looks.
Check what you receive
After you submit on the official site, it shows your TDAC to download and sends it to your email. Check that the name and passport number match your passport.
What a paid service must explain
A paid service should state that it is independent, that the government submission is free, what its own fee buys, and the total before payment. ThaiDigitalCard charges for guided data entry, application review, email support, and customer document access.
