Thailand Digital Arrival Card (TDAC) 2026: Complete Entry Guide (Free, Official, Step-by-Step)
Search Intent: You want the correct official TDAC process (not a scam), the exact 72-hour submission window, what information you need, and how to avoid the mistakes that cause delays at the airport or border.
Bottom line: Thailand Digital Arrival Card (TDAC) is the mandatory digital arrival declaration for non-Thai travelers. It replaces the old TM6 paper card and is completed online—free—within 3 days (72 hours) before arrival.
🏆 Quick Summary: 5 Key Takeaways
- 📍 The Essence: A mandatory digital arrival declaration for all non-Thai nationals entering Thailand by air, land, or sea.
- ⏰ Submission Window: Complete it within 72 hours (3 days) before your scheduled arrival date.
- 🆓 Cost: The official TDAC submission is 0 THB. If a site asks for payment, treat it as a red flag.
- 📱 Proof: You’ll get a QR code. Save it as a screenshot + PDF (double backup).
- ⚠️ Do NOT confuse it with a visa: TDAC is an arrival declaration. Your visa / exemption rules still apply separately.
“The first time you walk toward immigration in 2026, the vibe is different. No frantic paper cards—just people holding up calm little QR codes like boarding passes. TDAC isn’t ‘extra paperwork.’ It’s the last click that turns your trip into a smooth arrival.”
What It Feels Like: The Real Traveler Experience
Experience #1 — The “Gate Check” Moment
TDAC feels like the final checkbox in your pre-travel ritual—right next to “passport in bag” and “SIM plan ready.” In 2026, many airlines and check-in counters have become noticeably stricter. The most common scenario is simple: they ask, “Do you have your TDAC?” You open your phone, show the QR code, and suddenly everything moves again.
The relief is real. You’re not improvising with a pen mid-flight anymore. You’re arriving as someone who already did the admin work—calm, prepared, and ready to start the Thailand part of your trip.
Experience #2 — The 8-Minute Form That Saves 40 Minutes
The portal is mobile-friendly and usually quick (think: under 10 minutes if your documents are ready). The “Success” screen is the moment your shoulders drop.
You’ll receive a confirmation (often by email) containing your encrypted QR code—this is what you’ll show to airlines and immigration.
Here’s the real-world win: doing TDAC correctly at home prevents that stressful scramble in a crowded terminal where Wi-Fi is weak and you’re trying to type your accommodation address with 20% battery left.
Experience #3 — The “Small Mistakes” That Become Big Delays
TDAC is simple, but it’s also strict about matching your passport data. The biggest time-waster isn’t the form—it’s correcting errors at the worst moment. A typo in your passport number, a swapped surname/given name, or selecting the wrong arrival date can turn a smooth entry into a “please step aside” situation.
The good news: if you treat TDAC like a boarding pass (check it twice, store it twice), it becomes the easiest part of your trip.
Why TDAC Exists: The End of the TM6 Paper Card
For decades, the TM6 “blue card” was a rite of passage—filled out on planes with borrowed pens and half-remembered hotel addresses. TDAC replaces that old friction with a digital system that improves data accuracy, speeds up processing, and supports security and public health screening when needed.
Key Visitor Information (2026)
✅ Tip #1 — Do it like a pro (48-hour sweet spot)
The form is only allowed within 72 hours, so you can’t do it “a week early.” The best tactic is to submit about 48 hours before arrival—early enough to avoid last-minute panic, but still inside the allowed window.

⚠️ Warning #1 — Scams love “fast track” words
If a website asks for a “service fee,” “expedite fee,” or pushes you to pay to “avoid denial,” step back. The official TDAC submission is free on the official portal. Paywalls are a common scam pattern.
📌 Tip #2 — Save your QR in two places (no Wi-Fi dependency)
Airport Wi-Fi can be unreliable. Keep a high-resolution screenshot in your Favorites album and also save the email/PDF in a cloud folder (Google Drive/iCloud). Two storage points = zero stress.

TDAC Prep Checklist (So You Finish in One Clean Shot)
- Passport in hand (and check the MRZ lines at the bottom).
- Flight number for the final leg into Thailand.
- Accommodation address (hotel name + district/area is usually enough—keep your booking page open).
- Contact details you actually receive emails on (double-check spelling).
- Travel history/health declaration details ready (don’t guess; be accurate).
- Backup plan: screenshot + PDF saved before you leave home.
72-Hour Timeline (Simple “Do This When” Plan)
- T-72 to T-48 hours: Prepare details (passport, flight, hotel). Pick a calm moment to submit.
- T-48 hours: Submit TDAC on the official portal. Save the QR immediately.
- T-24 hours: Recheck your saved QR screenshot + the email/PDF backup.
- Travel day: Show QR at airline check-in (if asked) and again at immigration.
TDAC vs ETA vs Visa: Don’t Waste Time on the Wrong Thing
Most confusion in 2026 comes from mixing three different “permission layers.” Here’s the clean mental model: TDAC = arrival declaration. Visa/exemption = permission to stay. ETA = separate pre-screening concept (often mentioned online, but travelers commonly only need TDAC + correct visa/exemption).
| TDAC (Arrival Card) | Visa / Exemption | ETA (Pre-Screening) |
|---|---|---|
| Mandatory? Yes for non-Thai entries. Purpose: Arrival declaration + travel details. |
Mandatory? Depends on nationality/purpose. Purpose: Permission to enter/stay (length & type). |
Mandatory? Often discussed, but travelers should verify current official rules. Purpose: Security pre-authorization concept. |
| When: Within 72 hours before arrival. Output: QR code. |
When: Before travel (varies). Output: Visa stamp/e-visa/entry permission. |
When: Before travel (varies). Output: Approval to board/enter (if applicable). |
🔴 Insider Hacks: Avoiding Entry Headaches
- Group Feature: If traveling with family, use the group option (where available) to reduce repeated typing—but still save each person’s QR separately.
- The 72-Hour Hard Lock: If you try too early, the system may block your arrival date selection. Don’t fight it—plan the T-48 hour submission.
- MRZ Accuracy: If the portal offers passport scanning, still visually confirm the extracted name/number. OCR errors are rare but brutal when they happen.
Step-by-Step: TDAC Submission (Fast, Clean, No Guessing)
- Go to the official portal: tdac.immigration.go.th. Select language (English/Korean may be available depending on updates).
- Enter passport details: Use passport scan/MRZ if available, or type carefully. Confirm name spelling matches your passport exactly.
- Add travel details: Input your arrival date, port of entry, and flight number (use the final leg into Thailand).
- Accommodation: Add hotel name and address/district. Keep your booking open in another tab to avoid mistakes.
- Declaration section: Answer health/travel history questions honestly and consistently.
- Finish + store the QR: Save the QR screen as a screenshot, then download/save the confirmation email or PDF. You’re done.
Frequently Asked Questions (TDAC 2026)
Q1) Does the TDAC cost anything?
A: The official TDAC submission is free (0 THB). If any website asks for payment to “submit TDAC,” treat it as suspicious.
“`
Q2) When exactly can I submit TDAC?
A: You must submit within 72 hours (3 days) before your arrival date. If you try too early, the system may block the date selection.
Q3) Do children and infants need TDAC too?
A: Yes. Every traveler (including children/infants) needs their own TDAC record/QR.
Q4) Is TDAC the same as a visa?
A: No. TDAC is an arrival declaration. Visa/exemption rules still apply separately.
Q5) What if I didn’t receive the QR email?
A: Check spam/junk first. Also keep the QR screenshot saved. If needed, revisit the portal with your reference details to retrieve/update.
Q6) Can I edit my TDAC after submission?

Q7) Do I need TDAC if I’m only transiting Thailand?
A: If you do not pass through immigration (airside transit), requirements may differ. If you will enter Thailand through immigration—even briefly—assume TDAC is required and verify before travel.
Q8) What should I show at the airport?
A: Your TDAC QR code. Keep it ready on your phone and also as a backup PDF/screenshot.
