Use this page to understand how to check your Thailand Digital Arrival Card (TDAC) details, confirm whether your TDAC information has been submitted correctly, and know what to do if you cannot find your confirmation email or QR code.

TDAC is required for non-Thai nationals entering Thailand, and the official TDAC process should be completed before entry. The official TDAC website states that foreign travelers should submit arrival card information 3 days in advance of their arrival date in Thailand, and the official website also states “No Fees.” 

Important Notice

Thailand Digital Arrival Card (TDAC) is an independent informational and traveler assistance Google Site. This site helps travelers understand TDAC status checking, confirmation, updates, common email issues, and arrival preparation.

This site is not the official Thai Immigration website, not a government authority, and not affiliated with Thai Immigration, any embassy, or any government department.

The official TDAC system is free through the Thai Immigration Bureau website. Any independent assistance fee should be clearly disclosed as a service, guidance, review, or support fee — not as a Thai government fee.

Quick Answer: How to Check TDAC Status

To check or update TDAC information through the official process, travelers may need details such as:

• TH Digital Arrival Card No. 

• Date of Birth 

• Nationality / Citizenship 

The official TDAC guide says the update/search process asks travelers to enter the TH Digital Arrival Card No., Date of Birth, and Nationality/Citizenship, then click Search. 

If you used an independent assistance service, you may also check your service request status using the email address or reference number provided by that service.

Two Types of TDAC Status

It is important to understand the difference between official TDAC status and assistance request status.

1. Official TDAC Status

This refers to the TDAC information submitted through the official Thai Immigration system. You may need your TDAC number, date of birth, and nationality/citizenship to search or update your submitted information. 

2. Assistance Request Status

If you used a third-party assistance service, your service provider may give you a booking number, request number, or email-based tracking option. This only shows the status of your support request, not a separate government status.

What Information May Be Needed to Check TDAC?

To check TDAC status or request update support, keep these details ready:

• Full name as shown on passport 

• Passport number 

• Date of birth 

• Nationality / citizenship 

• Arrival date in Thailand 

• Email address used during submission 

• TH Digital Arrival Card No., if available 

• Flight number or arrival details 

• Hotel or Thailand address 

• Reference number, if using an assistance service 

The official TDAC guide states that the submission process includes personal information, passport details, trip information, accommodation information, health status information, and email address for receiving the Thailand Digital Arrival Card.

Where Can You Find Your TDAC Confirmation?

After TDAC submission, you should check:

• Your email inbox 

• Spam folder 

• Junk folder 

• Promotions folder, if using Gmail 

• Downloads folder 

• Screenshots folder 

• PDF files on your phone 

• Messages from your assistance provider, if applicable 

The official guide says travelers can download the Thailand Digital Arrival Card and can also download or print a copy from the email address provided during submission.

What If You Did Not Receive TDAC Email?

If you do not receive your TDAC email, do not panic. First check your inbox carefully.

Try these steps:

1. Check your spam or junk folder 

2. Search your inbox for “TDAC” or “Thailand Digital Arrival Card” 

3. Check whether you entered the correct email address 

4. Check your internet connection 

5. Check if the confirmation was downloaded already 

6. Contact your assistance provider, if you used one 

7. Use the official update/search option if you have your TDAC number 

If you still cannot locate the confirmation, keep your passport and travel details ready and seek proper support before travel.

What If Your TDAC Details Are Wrong?

If your submitted TDAC information has a mistake, you may need to update it before travel. The official TDAC guide says the update process allows travelers to search using required information, confirm the correction, edit details as necessary, review the information, and submit the updated form. 

You may need to update TDAC if:

• Your hotel changed 

• Your flight changed 

• Your arrival date changed 

• Your Thailand address changed 

• Your travel route changed 

• Your email was entered incorrectly 

• Your information was incomplete

What If You Lost Your TDAC Number?

If you lost your TDAC number, first check your email, downloads, screenshots, and any communication from the service or official system. Search for terms like:

• TDAC 

• Thailand Digital Arrival Card 

• Arrival Card 

• Thailand Immigration 

• QR code 

• Confirmation 

If you used an assistance service, contact support using your email address, passport name, arrival date, or reference number. Do not share sensitive passport data through unsafe channels.

Can You Travel Without TDAC Confirmation?

Foreign travelers entering Thailand should complete TDAC before entry. The official guide states that all non-Thai nationals entering the Kingdom of Thailand are required to complete TDAC online before entry. 

Best practice before travel:

• Complete TDAC within the allowed time 

• Save your confirmation 

• Keep a digital copy offline 

• Take a screenshot 

• Print a backup copy, if possible 

• Keep your passport and travel documents ready 

Do not wait until the immigration counter to handle missing confirmation issues unless there is no other option.

What to Check Before Contacting Support

Before contacting support, prepare:

• Passport name 

• Email address used 

• Arrival date 

• Flight number 

• Hotel or Thailand address 

• Reference number, if available 

• TDAC number, if available 

• Screenshot of the issue, if available 

This helps support teams understand your case faster and reduces back-and-forth communication.

Do not share passport information through:

• Public comments

• Clear disclaimer 

• Clear service fee disclosure 

• Privacy policy 

• Data protection policy 

• Contact information 

• Secure form handling 

• No false government branding 

• No guaranteed immigration approval claim
