How it works
Enter your passport, residence, travel, accommodation, and contact details once. The site generates a TDAC filler script with your values baked in. Open the official TDAC form, run the script, review, submit.
Thailand Digital Arrival Card helper
TDAC Auto-Fill: fill Thailand's free official arrival card faster
The official TDAC is free at tdac.immigration.go.th. Visiting Thailand once? Just fill it in by hand there, you don't need this helper. It is only worth it if you visit Thailand often and don't want to retype your details every trip.
Save your details once and auto-fill the free official Thailand Digital Arrival Card (TDAC) on every trip. Choose the device you actually use, build your personal script, then install it with simple step-by-step instructions after a one-time €5 payment.
Not the official TDAC website. Asia Tour Desk is an independent helper and is not affiliated with the Thai Immigration Bureau or the Thai government. The Thailand Digital Arrival Card itself is free at the official site tdac.immigration.go.th. Our optional €5 tool only auto-fills that official form for you; you review and submit it yourself.
Choose iPhone, Android, or Desktop to continue.
Your data stays with you
Your traveller profile is stored only in your browser. We never see your passport number, never submit the TDAC on your behalf, and never touch your QR code.
What changes each trip
Travel details like arrival date, flight number, country of boarding, and purpose should be updated for every new trip to Thailand.

TDAC Auto-Fill FAQ
Is this the official TDAC website?
No. Asia Tour Desk is an independent helper and is not affiliated with the Thai Immigration Bureau. The official Thailand Digital Arrival Card is free at tdac.immigration.go.th, and that is where you submit it.
Is the Thailand Digital Arrival Card free?
Yes. Submitting the TDAC on the official site is free. You never need to pay anyone to get a TDAC. Our €5 fee is only for the optional auto-fill tool that saves you typing on the official form.
What does the TDAC Auto-Fill tool actually do?
You enter your passport, residence, travel, accommodation and contact details once. The site builds a personal script that types those values into the official TDAC form for you, on iPhone (Shortcuts), Android (Chrome bookmarklet) or desktop. You check every field and press Submit yourself.
Do you submit the TDAC for me or store my passport details?
No. We never submit anything on your behalf and we never receive your passport number, name or travel details. Your profile is saved only in your own browser (localStorage). Our server only checks that the payment went through.
When do I have to submit the TDAC?
The official rule is within 3 days (72 hours) before your arrival in Thailand, including the arrival day. All non-Thai nationals need one for every entry by air, land or sea.
Who is the auto-fill tool for?
Frequent travellers, digital nomads doing regular border crossings, and anyone tired of retyping the same 25+ fields each trip. If you go to Thailand once, filling the free official form by hand is perfectly fine.
What if it does not work on my device?
