Thailand 
Many believe that Thailand is always completely visa-free and that a passport is sufficient. For tourism, this may be true in some cases, but in 2026, the TDAC is what usually complicates matters, as it is a mandatory digital registration for entry even when you do not apply for a visa in advance.
TDAC stands for Thailand Digital Arrival Card and replaces the old paper form you used to receive on the plane. You fill in details about your trip, your address in Thailand, and health information, and you receive a confirmation that is checked upon entry.
What is TDAC and Who Needs It in 2026
TDAC is not a visa. It is a digital entry registration linked to your passport number and your trip.
The requirement generally applies to everyone arriving internationally, regardless of whether you are entering under visa-free rules or with a visa. Exceptions may exist for certain transit arrangements and diplomatic passports, but expect that you will need TDAC if you are passing through immigration.
Cost of Thailand TDAC 2026
The TDAC itself from Thai authorities is usually free of charge. When you see a price, it is almost always a service fee from an agent or a platform that helps you fill out and submit your application.
As a guideline, such services often range from about 150 to 600 SEK per person, depending on how fast the processing and support included are. If you are traveling as a family, it can sometimes be cheaper per person if the applications are made in the same order.
Tip: If a site tries to sell TDAC as a visa for several thousand kronor, back away and check the website address before you pay.

How to Apply for TDAC Step by Step
Start by having your passport in front of you. You need the same passport number you are traveling on, and the details must match exactly.
Then fill in your personal information and travel details. This usually includes arrival date, flight number, where you will stay the first night, and contact information.
Enter the address in Thailand. The hotel name and location are usually sufficient, but have your booking confirmation ready so you do not guess the spelling.
You may encounter health questions and questions about previous travels. Answer factually, and do not guess dates if you are unsure.
Once you submit, you will receive a confirmation. Save it as a PDF and also have a screenshot on your phone, as connectivity upon arrival may be slow.
Tip: If you are traveling in a group, fill in one person at a time and double-check the passport number before moving on to the next.
Common Mistakes That Can Stop You at Entry
The most common mistake is that people enter the wrong passport number or confuse the number 0 with the letter O. The second most common error is entering the wrong arrival date when changing flights or during layovers.
Another classic mistake is the address in Thailand. If you are going to multiple cities, provide the accommodation for the first night, not the last.
TDAC and Visa Are Not the Same Thing
TDAC does not replace a visa if you actually need a visa for your trip, such as for longer stays, special purposes, or if you do not qualify for visa-free entry. TDAC is more like a digital entry form that complements your travel arrangements.
If you are unsure whether you need a visa in addition to TDAC, you can get help clarifying this through VIZA.se, especially if you plan to stay long or enter multiple times.
Practical Advice for 2026
Complete the TDAC when your flight times are confirmed, but not at the last minute. Aim for 48 to 72 hours before departure to have time to correct any details if something goes wrong.
Ensure your passport has at least six months of validity remaining upon entry, as this is a common requirement in the region. Also, make sure that the name in the TDAC matches the machine-readable line of the passport, meaning without extra middle names or nicknames.
