Traveling to Thailand in 2025? The Thailand Digital Arrival Card (TDAC) is a mandatory requirement for all foreign travelers starting 1st May 2025. This electronic form replaces the old paper TM6, streamlining immigration with a digital process. But what happens if you arrive at the airport and realize, “I forgot to fill out my TDAC”? Don’t panic! This comprehensive guide explains what to do if you forget to fill your TDAC, offering two practical solutions to ensure a smooth entry into Thailand. Whether you’re landing at Suvarnabhumi, Don Mueang, or Phuket International Airport, we’ve got you covered with actionable steps, pros, cons, and insider tips.
Why the TDAC Is Mandatory for Travelers in 2025
Starting 1st May 2025, every foreign traveler entering Thailand by air, land, or sea must complete the Thailand Digital Arrival Card (TDAC) at least three days before arrival. The TDAC collects essential details like your passport information, travel plans, accommodation, and a health declaration. This digital system enhances security, reduces paperwork, and speeds up immigration processing. Failing to submit your TDAC in advance can lead to delays or complications at the airport, so it’s critical to plan ahead.
But life happens, and forgetting to fill out the TDAC is a common oversight, especially for first-time visitors or those juggling busy travel schedules. If you find yourself at the airport without a completed TDAC, don’t worry—there are solutions. Below, we outline two options to handle this situation, complete with their advantages, drawbacks, and step-by-step guidance.
Option 1: Contact an Immigration Officer for Assistance
If you arrive at a Thai airport without a completed TDAC, your first option is to seek help from an immigration officer. Thai airports like Suvarnabhumi and Phuket International are equipped to assist travelers who haven’t submitted their TDAC in advance. Here’s how it works:
Step-by-Step: Getting Assistance from an Immigration Officer
- Locate the Immigration Help Desk: Upon arriving at the airport, head to the immigration area. Look for signs pointing to the “Help Desk” or “Immigration Assistance” counter. At major airports, these desks are staffed to handle TDAC-related issues.
- Explain Your Situation: Politely inform the officer that you forgot to fill out your TDAC. Be prepared to show your passport and travel documents.
- Follow Instructions: The officer will guide you to a self-service kiosk or a designated area where you can complete the TDAC form on-site. Some airports may provide a temporary Wi-Fi connection for this purpose.
- Complete the Form: You’ll need to enter your personal details, travel information, and health declaration. Once submitted, you’ll receive a QR code or confirmation to present at the immigration checkpoint.
- Proceed to Immigration: With your TDAC completed, join the immigration queue and present your QR code, passport, and other required documents.
Pros of Option 1
- No Additional Cost: Completing the TDAC at the airport is free, as the form itself has no submission fee.
- Official Support: Immigration officers are trained to assist travelers, ensuring you meet the mandatory requirement.
- Accessible at All Major Airports: Whether you’re landing in Bangkok, Chiang Mai, or Krabi, help desks are available.
Cons of Option 1
- Internet Dependency: You’ll need a stable internet connection to access the TDAC portal. While some airports offer free Wi-Fi, it can be slow or unreliable during peak hours.
- Language Barriers: Immigration officers typically assist in English or Thai. If you’re not fluent in either language, explaining your situation or understanding instructions can be challenging.
- Time-Consuming: Completing the TDAC on-site adds extra time to your airport processing. Expect delays, especially during busy travel seasons like summer or Thai holidays.
- Stressful Experience: After a long flight, navigating an unfamiliar airport and dealing with immigration issues can feel overwhelming, particularly for families or solo travelers.
Insider Tip
If you choose this option, stay calm and patient. Bring a fully charged smartphone or tablet to access the TDAC portal quickly. If possible, have your travel details (flight number, hotel address, etc.) saved in a note app to speed up the process.
Option 2: Quickly Apply with TDAC.info and Get Your Card in 5 Minutes
For a faster, more convenient solution, apply for your TDAC through tdac.info right at the airport. Our platform is designed to help travelers complete their TDAC in just 5 minutes, ensuring you breeze through immigration without unnecessary stress. Here’s how to do it:

What Happens If You Don’t Fill Out the TDAC at All?
The TDAC is mandatory for all foreign travelers entering Thailand from 1st May 2025, with exceptions only for transit passengers not passing through immigration or those using a Border Pass. If you arrive without a TDAC and don’t complete it at the airport, you may face:
- Entry Delays: Immigration officers will require you to fill out the TDAC before processing your entry, leading to long wait times.
- Additional Screening: Failure to comply could trigger extra checks, adding stress to your arrival.
- Potential Fines or Denial: In rare cases, repeated non-compliance might result in penalties or, worst-case, entry denial, though Thai authorities typically prioritize assistance over punishment.
To avoid these issues, always aim to complete your TDAC before departure. If you forget, use one of the two options above to resolve it quickly at the airport.
Tips to Avoid Forgetting Your TDAC in the Future
Prevention is better than a cure! Here are practical tips to ensure you never forget your TDAC again:

- Inform Your Travel Companions: If traveling with others, remind them to fill out their TDAC, as each traveler (including children) needs a separate form.
