When you arrive in Thailand, do you ever worry about losing your passport or waiting in line at customs? Thailand has an app that could help make your experience smoother. This app is called THIM, and it is a pilot program launched by the Thai Immigration Bureau.
THIM stands for Thailand Immigration Management System.
It allows you to submit your travel information online while you’re still on the plane. This helps you avoid the stress of searching for documents when you’re in line at customs.
You still need to use a TDAC, or Thailand Digital Arrival Card. This has been mandatory since May 2025 for all tourists arriving by air, land, or sea. THIM is similar to TDAC, aiming to make the arrival process easier and faster for visitors to Thailand.
The app was created with the help of Amazon Web Services and Digital Identity Co. Its main goals are to reduce the use of paper documents, lower the number of mistakes, and help reduce the length of queues at immigration. THIM uses a system that verifies your information against your passport’s chip, reducing errors and helping you pass through immigration more quickly.
Here’s what you can do with the THIM app:
- Submit digital arrival cards for Thailand.
- Keep track of your travel history to Thailand.
- Edit your information directly on the app.
- Receive updates about rule changes or important deadlines for Thailand.
- Add your family members to the same application.
If you visit Thailand frequently, the app will remember your details, so you don’t have to re-enter them every time. The THIM app is available in English, Chinese, Japanese, and Russian, with more languages to come.
However, there is a drawback.
THIM is still in the testing phase, and not all of its features are available across all regions. It will not be fully operational until October 1, 2026. So, if you’re visiting Thailand before this date, you should still fill out your TDAC form on the official website.
Also, keep in mind that Thailand is making changes to its visa rules for tourists.
The visa-free stay will be reduced from 60 days to 30 days for some travelers.
In the future, THIM is expected to become a key tool for all visitors to Thailand.
It will help with visa extensions, 90-day check-ins, and automated boarding for certain nationalities.
The Thai Immigration Bureau anticipates welcoming 30 million tourists each year.
They aim to create a positive impression for tourists visiting Thailand.
To sum up, THIM will make a real difference once it is fully launched for tourists.
It will help reduce waiting times and make arrivals less stressful. Until then, it is a useful tool to speed up your arrival process in Thailand, but not a replacement for the TDAC form.
Key takeaways about the THIM app for Thailand include:
- Pros: Easier to manage travel documents, convenient for adding people, secure storage of details, and helpful notifications.
- Cons: Still under testing, use TDAC until 2026, and shorter visa-free stays for some tourists.
- Who should use it: Travelers, families, or groups who prefer not to fill out forms repeatedly.
- Verdict: THIM is a promising app in theory, but it is not yet a full replacement for TDAC.
Use it as a travel document until 2026 for Thailand.
