Thailand’s transition to a digital entry system has brought efficiency, speed, and convenience to international arrivals. The Thailand Digital Arrival Card (TDAC) replaces the old paper-based TM6 form and helps both travelers and immigration officers process entry faster. Completing this form online before you fly saves you time and hassle at the airport, allowing for a smoother journey overall.
If you’re planning a trip to Thailand, this guide walks you through the exact process to submit your TDAC form online.
What You’ll Need to Fill Out the TDAC Online
Before you begin, gather the following information:
- Passport (valid for at least 6 months from the date of arrival)
- Flight details (airline, flight number, arrival date and time)
- Accommodation information (hotel/residence name and full address)
- Personal details (as listed on your passport)
- A working email address (for confirmation)
- A digital copy or photo of your passport’s data page

Step-by-Step Instructions to Fill Out the TDAC Online
Let’s break down the process into easy steps so you can complete your digital arrival card in just a few minutes.
Step 1: Visit the Official Website
Go to TDAC.info, which is the official service where travelers can submit their Thailand Digital Arrival Card. The site works well on both desktop and mobile, so you can fill it in wherever you are.
Step 2: Start Your Application
Click on “Apply Now” or the designated button to begin the form. You’ll be taken to a secure form submission page where you’ll be asked to enter the following:
- Full name (as it appears on your passport)
- Nationality
- Passport number
- Date of birth
- Email address
Make sure there are no spelling errors, especially in your name and passport number, as any mistakes could delay your entry.
Step 3: Enter Your Travel Information
Next, provide details about your trip:
- Airline name and flight number
- Date and time of arrival
- Purpose of visit (e.g., tourism, business, transit)
- Intended length of stay
Step 4: Fill In Accommodation Details
Provide the full address of your hotel, Airbnb, or any other place you’ll be staying:
- Hotel name or property owner’s name
- Street address
- Province and city (e.g., Bangkok, Chiang Mai)
- Zip code
Immigration uses this information to understand your movement within the country. Inaccurate or vague addresses may slow down processing.
Step 5: Upload a Copy of Your Passport
Upload a high-quality scan or photo of the data page of your passport. Make sure the image is clear and shows your photo, full name, passport number, expiration date, and issuing country.
Accepted formats include JPG, PNG, or PDF. File size should not exceed the platform’s limit (usually under 5MB).
Step 6: Review and Confirm Your Application
Before submitting, review all the information carefully:
- Double-check spelling
- Confirm travel and accommodation dates
- Ensure your passport image is readable
Once everything looks good, click “Submit”. You should receive a confirmation on the website immediately, and also via email.
After Submission: What Happens Next?
Once your application is submitted:
- You’ll receive a confirmation email with your TDAC reference.
- Keep a digital copy of the confirmation on your smartphone.
- Present it at the immigration counter upon arrival in Thailand if asked.
Immigration systems are often synced in real time, so they’ll likely already have your TDAC on file when you scan your passport.
Reminder: Apply at least 48 hours before your departure for best results. Use TDAC.info to avoid delays and errors.
Common Mistakes to Avoid
To ensure a smooth application, here are a few things to avoid:
- Typos in your passport number or name
- Incorrect arrival date or flight number
- Missing accommodation details
- Blurry or cropped passport images
- Submitting too close to your departure
Most issues arise from minor mistakes, but these can cause major delays if caught by immigration.
Can I Update My TDAC After Submission?
If you’ve made a mistake or your plans have changed (e.g., new hotel or flight), you can simply reapply with the corrected information at TDAC.info. There’s no penalty for submitting a new application.
However, make sure to do so at least 24 hours before your departure to allow for processing.

- Use a laptop or desktop for better visibility, although mobile works too
- Keep your passport image clear and in color
- Always double-check your entries before submitting
