Book Fast Track With Us — We Fill Out TDAC for You
If you book Bangkok Airport Fast Track with FastTrack Bangkok, you do not need to wrestle with the TDAC website yourself. Our team submits your Thailand Digital Arrival Card on your behalf using the official Immigration portal — with the passport, flight, and hotel details you send us when you confirm your booking.
You save time, avoid form errors, and arrive with TDAC already in the system. You still need a valid passport and the correct visa / entry permission for your nationality; TDAC remains a declaration, not a visa — we simply handle the paperwork side for our Fast Track customers.

What Is the Thailand Digital Arrival Card (TDAC)?
The Thailand Digital Arrival Card (TDAC) is an online arrival declaration managed by the Thai Immigration Bureau. It replaces the old paper TM.6 arrival card for most travelers and is designed to speed up data collection before you land — so officers already have your itinerary and accommodation details on file.
Important: TDAC is not a visa. It does not grant permission to enter Thailand. You still need a valid passport, an appropriate visa (or visa exemption / Visa on Arrival, if applicable), and you must meet all entry rules. TDAC is an additional requirement: a digital arrival form, not an entry document by itself.
The only official application portal is operated by Immigration:
https://tdac.immigration.go.th/
TDAC is free on the official Immigration website. Avoid random websites that sell “TDAC filing” as a standalone paid product — many are unnecessary or misleading. Exception: when you book Fast Track with us, TDAC completion is included as part of your service; we file it for you through the real tdac.immigration.go.th process, using your booking details — not a substitute portal.
Who Must Complete the TDAC?
In general, foreign nationals entering Thailand are expected to submit a TDAC before arrival (exact rules and exemptions can change; always check the official site and your airline before travel). Typical exemptions discussed in official guidance include passengers who do not pass immigration (e.g. international-to-international transit airside) and certain border-crossing scenarios — confirm current exemptions on tdac.immigration.go.th.
If you are flying into Suvarnabhumi (BKK) or Don Mueang (DMK) and clearing immigration as a visitor, TDAC must be on your pre-arrival checklist — unless you have already asked us to file it when you booked Fast Track with our team.
When Should You Submit?
You complete TDAC online before arrival, within the submission window shown on the official portal (commonly described as a few days before your arrival date — the exact window is defined by Immigration and may be updated). Do not wait until you are on the aircraft; submit early enough to fix typos and download or screenshot your confirmation.
Each visit to Thailand typically requires a new TDAC — it is tied to a specific entry.
What Information You Will Need
Have the following ready before you start (English is typically used for the form):
- Passport — Full name, nationality, date of birth, passport number, expiry date. Some flows allow scanning the MRZ (machine-readable zone) to reduce typing errors.
- Travel details — Flight number, arrival date/time, and port of entry (e.g. BKK or DMK).
- Accommodation in Thailand — Address of your first hotel or residence (many travelers use their first-night booking).
- Health / declaration questions — As required by the form at the time of travel (questions can be updated by authorities).
Group travel: the official system often supports multiple travelers in one submission (check the current limit on the portal — commonly up to a small group per application).
Step-by-Step: How to Submit TDAC Yourself
DIY option: follow the steps below. Fast Track customers: skip this section — we submit TDAC for you once you share your passport copy, flight number, arrival date, and first-night hotel address in WhatsApp.
- Open the official site: tdac.immigration.go.th.
- Choose the arrival card / TDAC flow and select your language if available.
- Enter passport and personal details carefully — core identity fields are often locked after submission; errors may require a new application.
- Add flight and accommodation information.
- Complete any health or customs-related declarations shown.
- Review everything, submit, and save your confirmation (QR code or reference — follow what the site provides at that time).
At Bangkok airports, keep the confirmation on your phone or carry a printed copy. Follow staff instructions — procedures can differ slightly by terminal and queue type.
TDAC vs Immigration Queues at Bangkok Airport
Completing TDAC helps Immigration process your data faster, but it does not shorten the physical queue at passport control during peak season. At Suvarnabhumi, regular immigration waits often reach 45–150 minutes November–April; Don Mueang is somewhat shorter but can still spike when several flights land together.
If you want to avoid standing in the main hall, the legal option is a licensed VIP Fast Track service: a personal escort meets you and guides you through the priority immigration lane. TDAC and Fast Track work together: you need both a completed arrival declaration and a way through the queue. With FastTrack Bangkok, we take care of TDAC for you when you book — plus priority immigration at BKK or DMK.

Common Mistakes Travelers Make
- Using a fake or paid “TDAC-only” scam site — Only tdac.immigration.go.th is the official portal. Booking Fast Track with a licensed operator who files TDAC for you (as we do) is different from paying a random third-party “TDAC service.”
- Typos in passport data — Mismatches slow you down at the counter.
- Wrong airport code — BKK vs DMK matters for arrival records.
- Vague hotel address — Use the full address from your booking confirmation.
- Assuming TDAC replaces a visa — It does not. Visa rules are unchanged.
Arriving Without Completing TDAC Online
If you could not submit online (device issues, last-minute travel), major airports including BKK and DMK may offer kiosks or on-site assistance — availability varies. However, relying on this can mean delays right before immigration. Whenever possible, complete TDAC in advance.
Summary Checklist Before You Fly to Bangkok
- Passport valid for at least 6 months (standard rule of thumb — confirm for your nationality).
- Visa or visa exemption / VOA as required.
- TDAC: either file it yourself on tdac.immigration.go.th and save the confirmation, or book Bangkok Airport Fast Track with us — we complete TDAC for you before you fly.
- Hotel booking details ready to show if asked (we use your first-night address for TDAC when you book with us).
- Fast Track: priority immigration at BKK or DMK — see packages.
