Overview
TDAC Pre-Flight Checklist: What Travellers Should Know The Thailand Digital Arrival Card (TDAC) is a mandatory document for most travellers entering Thailand. To ensure a smooth journey, it’s essential to prepare well in advance. This TDAC pre-flight checklist covers everything you need to know before your trip, from submission timelines to essential details. Read on to make your travel experience hassle-free.
What Is the Thailand Digital Arrival Card (TDAC)?
The TDAC is an electronic form that travellers must complete before arriving in Thailand. It replaces the traditional paper-based arrival card and streamlines the immigration process. The TDAC collects essential information such as your passport details, travel itinerary, and accommodation information. Completing this form is a crucial step for entry into Thailand.
When Should You Submit Your TDAC?
According to official guidelines, the TDAC must be submitted within 3 days before your arrival in Thailand. Submitting it earlier than this window may result in rejection, while leaving it too late could cause delays or complications at immigration. Plan ahead to ensure your submission is timely and accurate.
TDAC Pre-Flight Checklist
To avoid last-minute stress, follow this TDAC pre-flight checklist to ensure you’re fully prepared:
- Check Your Eligibility: Verify whether you need a TDAC based on your nationality and travel purpose. Most travellers, including tourists and business visitors, are required to complete the form.
- Gather Required Information: Have your passport, flight details, and accommodation information ready before starting the application.
- Submit Within the Window: Ensure you submit your TDAC within 3 days before your arrival date.
- Double-Check Your Details: Review all entered information for accuracy to avoid delays or rejection.
- Save a Copy: Once submitted, save a digital or printed copy of your TDAC confirmation for easy access at immigration.
How to Submit Your TDAC
The official portal for submitting the TDAC is https://tdac.immigration.go.th. This is the only platform authorized by the Thai government for TDAC submissions. However, if you prefer assistance with the process, independent services like ours are available for a fee of $15 per traveller. Please note that we are not affiliated with any government entity and provide independent support for completing the TDAC.
Common Mistakes to Avoid
Many travellers encounter issues with their TDAC due to simple mistakes. Here are some common pitfalls to watch out for:
- Incorrect Information: Typos or errors in passport numbers, flight details, or accommodation addresses can lead to delays.
- Submitting Too Early or Late: The TDAC must be submitted within the 3-day window before arrival. Submitting outside this timeframe may result in rejection.
- Not Saving Confirmation: Failing to save or print your TDAC confirmation can cause inconvenience at immigration.
What Happens After Submission?
Once you submit your TDAC, you’ll receive a confirmation that includes a QR code. Immigration officers will scan this code upon your arrival in Thailand. It’s important to note that submission does not guarantee entry; approval is at the discretion of Thai immigration authorities. Ensure you meet all entry requirements and have the necessary supporting documents.

While the official portal is straightforward, some travellers prefer using an independent service like ours for added convenience. Our service helps you complete the TDAC accurately and efficiently for a fee of $15 per traveller.
