The most common reasons a TDAC submission is rejected

Overview

The Most Common Reasons a TDAC Submission Is Rejected The Thailand Digital Arrival Card (TDAC) is a mandatory travel document for most visitors entering Thailand. While the application process is straightforward, many travelers face rejections due to avoidable mistakes. Understanding these common pitfalls can help ensure your submission is approved without delays.

This guide covers the most frequent reasons for TDAC rejection and how to avoid them. Remember, the official TDAC portal is the only government-approved platform, while applythaicard.com is an independent paid service ($15 per traveler) that assists with applications.

Incomplete or Inaccurate Personal Information

One of the top reasons for TDAC rejection is incorrect or missing personal details. Thai immigration authorities verify every piece of information against your passport and travel documents.

Common personal information mistakes include:

Always triple-check that your application matches your passport exactly, including special characters and spacing. Even minor discrepancies trigger automatic rejections.

• Name mismatches (middle names omitted or misspelled)
• Passport numbers with transposed digits
• Expired passport information (must be valid for 6+ months)
• Incorrect nationality or passport issuance country
• Wrong date of birth format (DD/MM/YYYY required)

Flight and Accommodation Details Errors

Your travel itinerary must precisely match your actual plans. Immigration cross-references your TDAC with airline manifests and hotel registries.

Frequent itinerary-related rejections occur when:

Update your application if your travel plans change after submission. You can resubmit up to 3 days before arrival.

• Flight numbers don't match booking confirmations
• Arrival dates are incorrect (account for time zones)
• Hotel names/addresses differ from reservations
• Transit passengers omit connecting flight details
• Multiple entries aren't properly documented

Technical Submission Issues

Digital applications face unique technical hurdles that lead to avoidable rejections.

Top technical rejection causes:

Use high-quality scans in proper lighting, and ensure stable internet during submission. Clear your browser cache if experiencing glitches.

• Uploading illegible passport scans (glare, cropped edges)
• Using unsupported file formats (JPEG/PDF under 2MB recommended)
• Submitting duplicate applications (creates system conflicts)
• Browser timeouts during payment processing
• Submitting too early (more than 3 days before arrival)

Health Declaration Mistakes

The health questionnaire is scrutinized, especially since pandemic protocols changed.

Rejections often occur when travelers:

Answer all health questions truthfully and completely. While Thailand currently has no COVID entry requirements, false declarations remain grounds for rejection.

• Inconsistently report vaccination status
• Fail to declare recent visits to high-risk areas
• Provide contradictory symptom information
• Omit required supporting documents

Payment Processing Failures

The TDAC requires payment to process, and transaction issues cause many avoidable rejections.

Common payment problems include:

Inform your bank of upcoming international charges and use a reliable payment method. Save all transaction receipts until you receive approval.

• Card declines due to international transaction blocks
• Insufficient funds for the fee amount
• Timeout before payment completion
• Using unsupported payment methods

If rejected, you'll typically receive an email explaining why. Address the issues and resubmit immediately, as processing can take several hours.

• Apply within the 72-hour pre-arrival window
• Cross-verify all data with your passport
• Double-check flight and accommodation details
• Use high-quality document scans
