Introduction
Most Thailand Digital Arrival Card problems come from small data errors rather than obscure rules. A wrong passport digit, an inverted arrival date or a mistyped email can create more trouble than almost anything else on the form.
This page lists the mistakes travellers make most often so you can catch them before payment. For the wider process, see the complete TDAC guide and the requirements checklist.
Passport errors
Enter names, passport number, nationality, date of birth and gender exactly as shown in the passport. Do not shorten names, swap given and family names, or reuse another traveller's passport number.
Families should be especially careful not to mix passports. See the families and groups guide if you are preparing more than one application.
Arrival and departure mistakes
Use the date you expect to enter Thailand. Arrival date controls VisaPal eligibility and whether the request can be submitted immediately or must wait as a pre-booking. Departure dates should not be earlier than arrival.
Timing rules are explained in when to apply.
Accommodation mistakes
Incomplete hotel names, missing districts or invented addresses are common when travellers rush. Enter the stay details you actually plan to use, including the address fields required by the TDAC.
If arrangements are still changing, wait until the details are reliable enough to enter accurately rather than guessing simply to finish the form.
Flight information
If you are arriving by air, have your itinerary available so flight numbers and related transport details are entered correctly. Mixing up outbound and inbound flights, or using an old booking reference instead of the flight number the form asks for, creates avoidable follow-up.
Health declaration
The TDAC asks travellers to declare countries or territories stayed in during the previous 14 days before arrival. Incomplete or guessed travel history is easy to get wrong when people rush.
VisaPal does not invent additional medical requirements on this page. Where separate health or vaccination rules apply to your journey, confirm them through official guidance. How VisaPal handles application information is set out in the Privacy Policy.
Timing mistakes
- assuming Thailand Immigration accepts TDAC submission seven days early
- treating a VisaPal pre-booking as proof the TDAC is already submitted
- applying more than seven days ahead and expecting VisaPal to accept the request
- leaving the form until transit with incomplete passport or hotel details
Official submission is currently within three days before arrival, including the arrival date. VisaPal can accept assistance requests up to seven days ahead and holds earlier requests securely until eligible.
Why reviewing your application matters
The review step exists so you can catch mistakes before payment. Check passport fields, dates, flight details, accommodation and email address one more time. Confirm the information is accurate and that you authorise VisaPal to submit on your behalf.
VisaPal helps reduce avoidable errors by guiding the application and reviewing requests before submission when eligible, but it still relies on the details you enter. Service conditions are in the Terms of Use.
Frequently asked questions
What is the most common TDAC mistake?
Passport typos are among the most frequent problems: incorrect passport numbers, mistyped names or dates of birth that do not match the passport.
Can VisaPal fix a mistake after payment?
Contact support promptly with your application reference. Whether a correction is still possible depends on how far processing has progressed. Reviewing carefully before payment remains the safest approach.
Does an email typo matter?
Yes. VisaPal emails the completed TDAC to the address you provide. A mistyped email can mean you never receive the document.
What if I enter the wrong arrival date?
Arrival date affects eligibility and whether the request is processed immediately or held as a pre-booking. Correct it before payment where possible, or contact support quickly if you notice the error afterwards.
Where can I check the information I need?
Use the requirements checklist before you start, then follow the how to apply steps and review screen carefully.
Does VisaPal invent health requirements?
No. VisaPal collects the recent travel history information needed for the TDAC application. Separate health or vaccination rules, where relevant, should be checked through official guidance.
More answers are collected in the TDAC FAQ.
