The Thailand Digital Arrival Card (TDAC) is a free, mandatory online form that every non-Thai traveler must submit within 72 hours before arriving in Thailand by air, land, or sea. Launched on May 1, 2025, the TDAC replaced the old paper TM6 card and is completed entirely online at the official government portal. This guide covers everything you need to know about the TDAC – from how to apply to what happens if your application is rejected.
What Is the Thailand Digital Arrival Card (TDAC)?
The TDAC is Thailand’s mandatory electronic travel declaration system. Every non-Thai national entering the Kingdom must complete the TDAC online before arrival, regardless of visa status or nationality. The system is managed by the Thai Immigration Bureau and accessible at tdac.immigration.go.th.
The Thailand Digital Arrival Card serves as the modern replacement for the paper-based TM6 arrival/departure card that travelers filled out on planes or at immigration counters for decades. The digital transition streamlines the entry process, reduces paperwork at immigration checkpoints, and allows Thai authorities to process travelers more efficiently.
The TDAC applies to all entry points into Thailand:
– Air arrivals at Suvarnabhumi, Don Mueang, Chiang Mai, Phuket, and other international airports
– Land border crossings from Cambodia, Laos, Myanmar, and Malaysia
– Sea arrivals including cruise ships, ferries, and private vessels
History: From TM6 to TDAC
The paper TM6 form was a staple of Thai travel for over 40 years. Travelers received the small white card on flights or at border crossings, filled it out by hand, and surrendered the arrival half to immigration officers. The Thai government announced the transition to a fully digital system in early 2025, with the TDAC going live on May 1, 2025.
Key differences between the old TM6 and the new TDAC:
– TM6: Paper form, filled by hand, distributed on flights or at borders
– TDAC: Online form, submitted digitally before travel, accessible from any device
– TM6: No advance submission required
– TDAC: Must be submitted within 72 hours before arrival
How to Apply for the TDAC: Step-by-Step Guide
Applying for the Thailand TDAC takes approximately 10-15 minutes. The entire process happens online at the official portal. Here is how to apply for the TDAC step by step:
Step 1: Visit the official website
Go to tdac.immigration.go.th – this is the only official TDAC application portal. Avoid third-party websites that may charge unnecessary fees.
Step 2: Select your entry type
Choose whether you are entering Thailand by air, land, or sea. The TDAC form adjusts slightly based on your entry method.
Step 3: Enter personal details
Provide your full name (as shown on passport), date of birth, nationality, gender, and passport number. The TDAC system validates passport details against international databases.
Step 4: Add travel information
Enter your flight number (or transport details for land/sea entry), arrival date, and port of entry. The TDAC requires this to link your declaration to your specific arrival.
Step 5: Provide accommodation details
Enter the name and address of your hotel, resort, or accommodation in Thailand. If staying at multiple locations, use the address where you will spend the first night.
Step 6: Review and submit
Double-check all information before submitting. Incorrect passport numbers or dates are the most common reasons for TDAC delays or rejections.
Step 7: Save your confirmation
After submission, you will receive a confirmation email with a QR code. Save this to your phone or print it – immigration officers may ask to see your TDAC confirmation at the port of entry.
TDAC Requirements and Documents
The TDAC requirements are straightforward. You need the following documents and information to complete your Thailand Digital Arrival Card:
Mandatory documents:
– Valid passport with at least 6 months remaining validity
– Confirmed flight booking (or transport details for land/sea entry)
– Accommodation address in Thailand (hotel name and address)
Information you must provide:
– Full name exactly as printed on your passport
– Passport number and expiry date
– Nationality and date of birth
– Flight number and arrival date
– Purpose of visit (tourism, business, transit, etc.)
– Contact phone number or email
Not required for the TDAC:
– Visa (the TDAC is separate from visa requirements)
– Travel insurance (though recommended)
– Proof of funds (may be checked at immigration but not part of TDAC)
– Passport photo (the TDAC is form-based, not photo-based)
All non-Thai nationals must complete the TDAC, including children. Parents or guardians can submit TDAC applications on behalf of minors using the child’s passport details.
TDAC Fees and Costs
The official TDAC is completely free of charge. The Thai government does not charge any fee for the Digital Arrival Card application. This is one of the most important facts about the TDAC – it costs nothing when you apply through the official portal.
Avoiding Third-Party Scams
Several unofficial websites offer to process TDAC applications for a fee, typically ranging from $15 to $50 USD. These sites are not affiliated with the Thai government and provide no additional value. They often:
– Charge fees for a free service
– Collect your personal data unnecessarily
– Delay your confirmation
– Provide incorrect or outdated information
Always apply for your TDAC directly at tdac.immigration.go.th. If a website asks for payment for the Thailand Digital Arrival Card, it is not the official portal.
TDAC Processing Time and Approval
TDAC approval is typically fast. Most travelers receive their TDAC confirmation within minutes of submission. In some cases, processing can take up to 24 hours.
Recommended timeline:
– Submit your TDAC at least 3 days (72 hours) before your arrival date
– The system opens for applications 72 hours before your scheduled arrival
– If you do not receive confirmation within 24 hours, check your spam folder
Checking Your TDAC Status
You can check your TDAC application status on the official website. Enter your passport number and date of birth to view the current status. Possible statuses include:
– Submitted: Application received and pending review
– Approved: TDAC confirmed, QR code generated
– Rejected: Application denied (see troubleshooting section below)
TDAC for Different Visa Types
The TDAC is required for all visa types. Whether you hold a tourist visa, business visa, or are entering under a visa exemption scheme, you must complete the TDAC before arrival.
| Visa Type | TDAC Required? | Notes |
|---|---|---|
| Tourist Visa | Yes | Standard application, tourism purpose |
| Business Visa | Yes | Include business contact details in accommodation field |
| Work Visa | Yes | Include employer address if known |
| Student Visa | Yes | Include educational institution address |
| Transit Visa | Yes, if clearing immigration | Transit passengers who stay airside may be exempt |
| Visa on Arrival | Yes | Complete TDAC before arriving at the visa on arrival counter |
| Visa Exemption | Yes | Even visa-exempt nationals must complete the TDAC |
| e-Visa | Yes | The TDAC is separate from the e-Visa application |
The TDAC is not a visa. It is a mandatory arrival declaration that supplements whatever visa or entry permission you already hold.
TDAC by Nationality
All nationalities must complete the TDAC. However, some nationality-specific considerations apply.
US Citizens
American passport holders can enter Thailand under the visa exemption scheme for up to 60 days. The TDAC is still mandatory. US citizens should complete the TDAC at tdac.immigration.go.th at least 72 hours before departure. For the latest travel advisories, check the U.S. Embassy in Thailand website.
UK Citizens
British passport holders benefit from the same 60-day visa exemption as US citizens. The TDAC must be completed before arrival. UK citizens traveling for longer stays will need a visa in addition to the TDAC.
Indian Citizens
Indian passport holders typically need a visa to enter Thailand. The TDAC must be completed regardless of visa type. Indian citizens should ensure their passport details on the TDAC match their visa application exactly.
Chinese Citizens
Chinese passport holders can apply for visa on arrival (15 days) or obtain a tourist visa in advance. The TDAC is required in both cases. Chinese travelers should complete the TDAC before their flight to avoid delays at immigration.
German Citizens
German passport holders can enter Thailand under the visa exemption scheme for up to 60 days. The TDAC must be submitted online before arrival. German travelers should note that the TDAC does not extend the permitted stay duration.
Common TDAC Problems and Solutions
While the TDAC application process is generally smooth, some travelers encounter issues. Here are the most common TDAC problems and how to resolve them.
TDAC Rejection
TDAC applications can be rejected for several reasons:
– Incorrect passport number – Double-check every digit before submitting
– Name mismatch – Your name must match your passport exactly (including middle names)
– Expired passport – Your passport must be valid for at least 6 months beyond arrival
– Duplicate application – Submitting multiple TDAC forms for the same trip causes conflicts
Solution: Correct the error and resubmit. There is no limit on the number of TDAC submissions.
TDAC Confirmation Not Received
If you do not receive your TDAC confirmation email:
– Check your spam or junk email folder
– Verify you entered the correct email address
– Wait up to 24 hours before reapplying
– Try a different email address (Gmail, Outlook)
Overstay Rules
The TDAC does not grant permission to stay in Thailand beyond your visa or exemption period. If you plan to stay longer than initially permitted, you must:
– Apply for a visa extension at a Thai immigration office before your current permission expires
– Notify immigration if staying beyond 90 days (required by Thai law)
– Overstaying results in fines of 500 THB per day (capped at 20,000 THB), potential detention, and possible bans from re-entering Thailand
TDAC vs Embassy Visa vs Visa on Arrival
Understanding the difference between the TDAC and other entry methods helps you prepare correctly for your trip to Thailand.
Key point: The TDAC is required for everyone, regardless of whether you also need a visa. Think of the TDAC as a digital landing card, not a travel permit.
FAQ (Frequently Asked Questions)
How early can I fill TDAC for Thailand?
You can submit your TDAC application starting 72 hours (3 days) before your scheduled arrival date. The system does not accept applications submitted earlier than this window. Plan to complete your TDAC at least 2-3 days before your flight to allow time for any corrections if needed.
Does a TDAC for Thailand cost money?
No. The official TDAC is completely free. The Thai government does not charge any fee for the Digital Arrival Card. If a website asks you to pay for the TDAC, it is not the official portal. Always apply at tdac.immigration.go.th.
Which is the official TDAC website for Thailand?
The official TDAC website is tdac.immigration.go.th. This is the only government-approved portal for submitting your Thailand Digital Arrival Card. Be cautious of unofficial sites that mimic the official portal and charge fees.
What do American citizens need to enter Thailand?
US citizens need a valid passport (6+ months validity), a completed TDAC submitted online before arrival, and proof of onward travel. US passport holders can enter Thailand under the visa exemption scheme for up to 60 days without a pre-arranged visa.
Do I need to print my TDAC confirmation?
Printing your TDAC confirmation is recommended but not strictly required. Most travelers save the QR code to their phone. Immigration officers may ask to see your TDAC confirmation at the port of entry, so having a digital or printed copy ensures smooth processing.
What happens if I arrive in Thailand without a TDAC?
Arriving without a completed TDAC may result in delays at immigration. Some airports have kiosks where you can complete the TDAC on arrival, but this is not guaranteed. To avoid complications, always submit your TDAC online before traveling to Thailand.
Is the TDAC the same as a visa?
No. The TDAC is a mandatory arrival declaration, not a visa. It does not grant permission to enter or stay in Thailand. You still need a valid visa or qualify for visa exemption to enter the country. The TDAC is an additional requirement for all non-Thai nationals.
Do children need a TDAC for Thailand?
Yes. Every non-Thai national, including infants and children, must have a TDAC. Parents or guardians can submit TDAC applications on behalf of their children using the child’s passport details.
Can I edit my TDAC after submission?
If you need to correct information on a submitted TDAC, you should submit a new application. The system does not allow editing of previously submitted forms. Make sure to double-check all details, especially your passport number and arrival date, before clicking submit.
Do transit passengers need a TDAC?
Transit passengers who remain in the international transit area and do not clear Thai immigration do not need a TDAC. However, if you plan to leave the airport or clear immigration for any reason, you must complete the TDAC before arrival.
How long is the TDAC valid?
The TDAC is valid for a single entry into Thailand. If you leave Thailand and plan to return, you must submit a new TDAC application for each entry. The TDAC does not have an expiration date beyond your specific arrival date.
Do I need travel insurance for the TDAC?
Travel insurance is not required for the TDAC application. However, it is strongly recommended for all travelers to Thailand. Medical treatment in Thailand can be expensive, and travel insurance provides coverage for emergencies, trip cancellations, and lost belongings.
