What Is the Thailand Digital Arrival Card (TDAC) and Why It Exists
From TM6 to Digital Arrival — Thailand’s Shift to a Smarter System
For years, visitors to Thailand had to fill out the old TM6 paper arrival card handed out on airplanes or at the border. In 2025, the Thai government officially replaced it with the Thailand Digital Arrival Card (TDAC), a secure and convenient online platform designed to modernize travel entry procedures.
The TDAC Thailand form collects essential traveler data, such as flight details, accommodation, and purpose of visit, in advance, allowing authorities to pre-screen and manage entries efficiently.
Legal Requirement and Implementation Timeline
Introduced by Thailand’s Immigration Bureau and supported by the Ministry of Digital Economy and Society, the TDAC became mandatory for all international arrivals starting mid-2025. Completing the Thailand arrival card online is now a legal prerequisite for entry, much like completing an e-visa form in other countries.
Failure to register your details online could lead to delays at immigration or even denied entry, depending on compliance requirements. The form is available exclusively through the official Thai government portal, ensuring security and authenticity.
Who Needs to Submit the TDAC — and Who Is Exempt
Every foreign traveler entering Thailand by air, land, or sea must complete the Thailand digital arrival card before departure.
However, a few categories are exempt:
- Thai citizens returning home
- Diplomatic passport holders and accredited officials
- Transit passengers not passing through immigration
If you are visiting for tourism, business, study, or medical purposes, you will need to complete your TDAC Thailand registration online before arrival.
Key Preparations Before Filling Out the TDAC Thailand Form
Documents You Will Need for the Thailand Digital Arrival Card
Before starting your application, make sure you have the following:
- A valid passport with at least six months of validity
- Your confirmed flight ticket to Thailand
- Accommodation details (hotel booking or host address)
- A valid email address to receive confirmation
- Optional: Travel insurance policy details (recommended for smooth processing)
Having these ready will help you complete the Thailand arrival card online quickly and accurately.
Step-by-Step Guide: How to Fill the TDAC Thailand Online
Filling out the Thailand Digital Arrival Card (TDAC) is now a straightforward online process — no more paper forms on planes or long queues at immigration. Below is a step-by-step guide to help you complete the Thailand arrival card online correctly and confidently.
Accessing the Official TDAC Thailand Portal
To begin, visit the official Thailand Digital Arrival Card portal provided by the Thai government.
Use only the official site — https://www.immigration.go.th — or directly through https://tdac.immigration.go.th once fully deployed.
Avoid any third-party or unofficial links offering “express approval” or “fee-based assistance” — these are often scam sites that collect personal data illegally.
When you access the portal:
- Choose your preferred language (English or Thai).
- Ensure your browser is up to date and pop-ups are enabled.
- Have all your documents ready before you start.
Choosing Between Individual and Group Submission
The TDAC Thailand platform allows travelers to register as:
- Individual Applicants — for solo travelers or those filling the form separately.
- Group Submission — ideal for families or group tours, allowing one person to submit details for multiple travelers under the same booking.
For group applications, ensure all passports are valid and details are double-checked before submission to prevent mismatches or rejections.
Filling in Personal and Passport Information
Start by entering your personal details exactly as they appear on your passport:
- Full Name (Surname, Given Names)
- Gender and Date of Birth
- Nationality
- Passport Number and Expiry Date
Use uppercase letters and avoid nicknames or abbreviations. Inconsistent or misspelled data may cause delays when cross-referenced with Thailand’s immigration database.
This section helps Thai authorities verify your identity securely, improving both travel safety, for your travel insurance providers check here and border efficiency.
Entering Travel and Arrival Details
Next, input your travel itinerary and entry details:
- Flight Number (e.g., TG402 or QR836)
- Port of Entry (Bangkok Suvarnabhumi, Don Mueang, Phuket, or Chiang Mai)
- Purpose of Visit (Tourism, Business, Medical, Study, etc.)
- Intended Length of Stay
Ensure your information matches your boarding pass and e-ticket. Any discrepancy can cause unnecessary questioning upon arrival.
If you are unsure about the correct port of entry, verify it on your airline confirmation before submitting and you can check for cheap airlines here.
Adding Accommodation Information in Thailand
This section requires you to list your first-night stay address in Thailand — even if you plan to travel around later.
Enter the following accurately:
- Hotel name or host name
- Street address
- Province and postal code
- Contact number (hotel or host)
Travelers who haven’t booked accommodation yet can use a temporary address, such as the hotel reserved for their first few nights.
Providing clear, verifiable details helps immigration officials locate you in case of emergencies — a standard international travel protocol.
Completing the Health Declaration & Travel History
The health declaration portion of the Thailand digital arrival card focuses on public health and disease prevention. You will need to:
- Declare recent visits to countries with health alerts or outbreaks.
- Confirm you are not currently experiencing communicable disease symptoms.
This helps Thai authorities manage public safety while ensuring a smoother arrival process.
Be truthful — providing inaccurate health information can lead to entry denial or penalties under Thai law.
For updates on Thailand’s current travel health requirements, check the Ministry of Public Health’s travel advisory before your trip.
Previewing, Editing, and Submitting Your TDAC
Before submitting, carefully review all entered information on the confirmation page. Look for:
- Spelling errors in your name or passport number
- Incorrect flight or hotel details
- Missed questions or unchecked declarations
If everything looks accurate, click Submit.
The TDAC Thailand system will process your entry, and you’ll receive a confirmation page within minutes.
Obtaining and Saving the TDAC Confirmation
Once submitted successfully, you will receive a confirmation email containing your TDAC reference number and QR code.
Download or print this document — you will need to show it to immigration officers when you land in Thailand.
Keep both digital and printed copies of your Thailand Digital Arrival Card:
- Save a copy on your phone
- Print a paper version as a backup
Immigration officials may scan your QR code directly from your mobile device during entry checks.
For your security, confirm that your email confirmation comes from an official Thai government domain (e.g., @immigration.go.th) — not a third-party address.
Updating or Correcting Your Thailand Digital Arrival Card (TDAC)
Sometimes, travelers realize they entered incorrect details or need to update information after submission. Don’t worry — the TDAC Thailand system allows limited corrections.
What You Can Edit After Submission
You can usually edit:
- Contact details (email or phone)
- Accommodation address
- Flight number (if rebooked)
To make minor corrections, log in to your Thailand arrival card online account and navigate to “Manage Submissions.” Update the fields and re-save your details.
When You Must Submit a New TDAC Form
If your passport number, date of arrival, or personal identification details have changed, you’ll need to submit a new TDAC form.
This ensures your new record aligns correctly with Thailand’s immigration database.
Re-submitting a new Thailand digital arrival card does not incur any fee — it’s free of charge through the official portal.
Step-by-Step: How to Update or Correct Your TDAC
- Visit the official TDAC Thailand portal: https://tdac.immigration.go.th
- Log in using your registered email and TDAC reference number.
- Select “Edit or Update Submission.”

Scams, Fake Sites & Security Tips for TDAC Thailand
As Thailand transitions to digital entry procedures, scammers have taken advantage of the new Thailand Digital Arrival Card (TDAC) system. Many travelers have reported fake websites, phishing links, and paid “agents” pretending to help with the Thailand arrival card online. Understanding how to protect yourself is essential to keep your trip stress-free and your data secure.
How to Spot Fake “Thailand Arrival Card Online” Services
Here’s how to recognize and avoid scam websites pretending to be part of the TDAC Thailand system:
- Check the domain name:
Legitimate Thai government websites end with “.go.th” — anything else is fake.
Example of the real site: https://tdac.immigration.go.th - Look for HTTPS encryption:
The URL should start with “https://” (the “s” stands for secure). - No payment requests:
The official TDAC form is free. If a website asks for your credit card or payment, it’s a scam. - Beware of sponsored ads or pop-ups:
Scammers often buy ads to appear at the top of Google search results — always scroll down to find the official immigration link. - Avoid using agents:
You don’t need any “TDAC agency” or middleman. The form is simple and takes less than 10 minutes to fill out yourself.
For up-to-date alerts, you can check the Thai Immigration Bureau’s News Section where official warnings about fraudulent sites are posted regularly.
Tips to Protect Your Personal Information
Your passport, travel plans, and contact details are valuable — not just to you but also to scammers.
To stay safe while filling out the Thailand Digital Arrival Card:
- Use a private internet connection (not public Wi-Fi at cafés or airports).
- Install antivirus software and keep your browser updated.
- Double-check URLs before clicking.
- Never email or message your passport details to anyone claiming to “help with TDAC Thailand.”
- Regularly monitor your email for suspicious messages after submission.
Remember: if you’re ever unsure, verify directly through Thailand’s official government channels or contact your airline for guidance.
At the Airport & Immigration: What to Expect
Once you have submitted your Thailand Digital Arrival Card, you will experience a much smoother immigration process at Thai airports. Here is what you can expect upon arrival.
Presenting Your TDAC QR Code or Confirmation
When you arrive in Thailand, proceed to the Immigration Checkpoint. You’ll need to show:
- Your passport
- Your TDAC confirmation email (digital or printed)
- Your QR code generated after online submission
Immigration officers will scan your QR code to verify your details in the TDAC Thailand database.
Keep your phone battery charged or carry a printed copy in case of technical issues.
Officer Checks, Backups & Contingencies
If immigration officers can’t scan your QR code due to a system error or poor connectivity, they’ll manually confirm your data using your TDAC reference number.
Always keep a screenshot or PDF backup on your device. It helps ensure you don’t experience delays even if your email app or the system is temporarily down.
For official verification or travel entry updates, you can refer to the Airports of Thailand Public Relations page, which frequently posts updates about digital entry procedures.
If You Didn’t Complete the Thailand Arrival Card Online in Advance
If you forgot or were unable to complete your Thailand digital arrival card online, don’t panic. Some airports still have TDAC assistance kiosks or immigration help desks.
You will be directed to a counter where officers will guide you to complete your TDAC Thailand registration using available tablets or computers before you clear immigration.
However, completing the form before traveling is highly recommended — it saves time and prevents unexpected hold-ups upon arrival.
Tips & Best Practices for Smooth Entry
Applying for the Thailand Digital Arrival Card (TDAC) is simple when you know the right steps — but small mistakes can delay your entry or cause extra stress at the airport. Below are smart, field-tested tips to ensure a smooth TDAC Thailand online submission and hassle-free arrival.
Fill Within 72 Hours Before Arrival
Always complete your Thailand Digital Arrival Card within 72 hours of your scheduled arrival. This ensures your details — especially flight number and accommodation — stay accurate. Submitting too early might lead to discrepancies if your travel plan changes.
Use a Reliable Internet Connection and Device
The Thailand arrival card online form works best on modern browsers such as Chrome, Edge, or Safari. Avoid filling it out on unstable Wi-Fi networks, since losing connection mid-process can cause submission errors or incomplete uploads.
Double-Check All Fields (Names, Passport, Dates)
Even a single typo in your name or passport number can lead to delays at immigration. Before submitting, recheck each field carefully. The TDAC Thailand portal also allows you to preview before confirming — use that chance to correct any details.
Save Multiple Formats (PDF, Screenshot, or QR Code)
Once your form is approved, you’ll receive a TDAC QR confirmation. Save it as a PDF, take a screenshot, and keep it on your mobile device. You might need to show it to airline staff or immigration officers on arrival.
Carry a Backup Copy (Printed or Downloaded)
Thailand’s airports are well-connected, but technology can fail. Having a printed copy or a downloaded version ensures you’re never stuck without proof of submission, especially if your phone battery dies or Wi-Fi is down.
Keep Travel & Health Records Handy
During entry, immigration may verify details such as vaccination status or recent travel history. Keep digital or printed versions of your flight ticket, hotel booking, and health documentation in one folder. This helps officers verify your TDAC Thailand details quickly and smoothly.
Filling the Thailand Digital Arrival Card (TDAC) online is your key to a seamless entry into Thailand — saving time, reducing paperwork, and helping authorities streamline immigration. With just a few minutes of preparation, you can ensure your arrival goes smoothly and focus on what truly matters: enjoying Thailand’s breathtaking beaches, vibrant culture, and warm hospitality.
Whether you are visiting Bangkok’s floating markets or relaxing in Phuket, completing your Thailand arrival card online ahead of time gives you peace of mind and more time to explore.
Final Thoughts: Always use the official TDAC Thailand website (if updated by Thai Immigration) to submit your form. Avoid third-party intermediaries, double-check your data, and carry a copy of your confirmation. Safe travels!
FAQs, Troubleshooting & Common Issues with TDAC Thailand
Even with a streamlined digital process, travelers occasionally face minor hiccups. Here’s how to troubleshoot common issues with your Thailand Digital Arrival Card submission.
What to Do If TDAC Submission Fails
If your submission fails or the page won’t load:
- Clear your browser cache and cookies.
- Switch to Google Chrome or Microsoft Edge.
- Try again later during non-peak hours.
If issues persist, contact the Thai Immigration Bureau Support Center for technical help.
Can Airlines Ask for the TDAC at Check-in?
Yes. Some airlines may verify that you’ve completed your Thailand arrival card online before allowing boarding, especially for direct flights to Thailand.
It’s best to carry your TDAC confirmation email or printed copy during check-in to avoid last-minute complications.
If You Change Your Flight or Hotel After Submission
If your flight details or accommodation address change after submission, log in to the TDAC Thailand portal and update your record.
Small updates like hotel changes can be modified easily without re-submitting the entire form.
What Happens If You Miss the TDAC Deadline
The Thailand Digital Arrival Card should ideally be completed 24–48 hours before departure.
If you forget to submit in time, you’ll still be allowed to complete it upon arrival, but expect longer wait times at immigration.
Reusing or Reprinting Your TDAC
Each TDAC Thailand submission is valid for a single entry only.
If you leave Thailand and return later, you must fill a new Thailand digital arrival card for each trip.
You can, however, reprint or re-download your confirmation anytime from your email or the official portal if needed.
By understanding these steps and security measures, travelers can enjoy a safe, scam-free experience with the Thailand Digital Arrival Card (TDAC) — ensuring a smooth and secure journey from check-in to arrival.
