Starting May 1st, 2025, all non-Thai nationals entering Thailand by air, land, or sea are required to complete the Thailand Digital Arrival Card (TDAC) online before their trip. This new requirement replaces the old TM6 paper form and aims to simplify immigration, improve health screening, and boost national security. TDAC (Thailand Digital Arrival Card) is required for non-Thai travelers entering Thailand by air, land, or sea. You submit it online via the official TDAC site up to 72 hours (3 days) before arrival, and it replaces the old TM6 paper form.
In this guide, you’ll learn everything about TDAC Thailand — what it is, who needs it, and exactly how to register so you can travel smoothly without delays.
Quick facts: When to submit: within 72 hours before arrival • Official site: TDAC Immigration • Cost: no fee
What is the TDAC Thailand?
The Thailand Digital Arrival Card (TDAC) is a mandatory digital form introduced by the Thai Immigration Bureau. It replaces the previous TM6 form, which travelers once filled out by hand on arrival. The TDAC streamlines the process by letting travelers submit their information online ahead of time.
TDAC helps authorities:
- Monitor who enters the country
- Improve health and safety screening
- Eliminate the need for paper-based arrival/departure cards
Once completed, travelers receive a digital confirmation to show at immigration checkpoints — no printing required.
Who Needs to Complete the TDAC?
Every non-Thai citizen must complete the TDAC before entering Thailand — regardless of their visa type, travel purpose, or point of entry. This applies whether you’re visiting on a tourist visa, business visa, long-stay visa, or under the visa exemption scheme.
Even if you’re part of a family or travel group, each person must be registered. Fortunately, the TDAC system allows group submissions for easier processing.
Is TDAC a Visa?
No. The TDAC is not a visa and does not grant you permission to enter Thailand on its own. It is a pre-arrival immigration form that is required in addition to your visa or visa-exempt entry.
Travelers without a completed TDAC may face delays at immigration — or be asked to step aside to complete it before entry is granted.
When Can You Register TDAC?
You can fill out the TDAC:
- Up to 72 hours (3 days) before your arrival
- On the day of your trip, if necessary
The form is free and available in multiple languages, including English, Chinese, Japanese, Korean, and Russian. There’s no mobile app yet, but registration can be done easily on mobile or desktop browsers.
How to Register for the TDAC Thailand (Step-by-Step Guide)
Here is a clear step-by-step guide on how to complete your TDAC online. We recommend preparing your passport, flight details, and hotel information before starting.
Step 1 – Access the Official TDAC Website
To begin the process, go to https://tdac.immigration.go.th/arrival-card/#/home. Once the page has loaded, click on the “Arrival Card” option to initiate your TDAC registration.
Step 2 – Fill in Your Personal Information
After selecting “Arrival Card,” you will be directed to a form where you must fill in your personal details. This includes your nationality, travel document number (passport), full name, date of birth, and phone number. Fields marked with a red asterisk are mandatory. Once all required fields are completed, click to continue to the next step.
Step 3 – Enter Travel and Accommodation Details
In this step, you’ll need to input how you are entering Thailand—whether by air, land, or sea—along with your flight number or vehicle information. You will also be asked for your accommodation details. If you’re unsure of the full address, don’t worry—the system helps by narrowing options: once you select your province, the drop-down menus for district and sub-district will update accordingly, making it easier to complete accurately.
Step 4 – Complete the Health Declaration
Now proceed to the health declaration section. You’ll be asked to list the countries you’ve visited within the past couple of weeks. If you’ve been to a country flagged by Thai health authorities, you may be required to show proof of vaccination or undergo a health inspection upon arrival.
Step 5 – Submit and Save Your Confirmation
Before submitting, you have the option to click “Add Other Travelers” if you are traveling as a group or family. This lets you handle all TDAC applications at once. If you’re registering only for yourself, simply proceed to submit the application. After submission, you’ll receive an electronic confirmation via email. Save it to your device and consider uploading it to cloud storage like Google Drive or iCloud so you can access it at any time.
Step 6 – Show Your TDAC at Immigration
Upon arrival in Thailand, the immigration officer will ask to see your TDAC confirmation. You can simply show the digital version on your smartphone or tablet—no printout is required. Be sure not to delete this confirmation after entry, as you may be asked to present it again when leaving the country.

TDAC Thailand – Quick FAQ
Is the TDAC free?
Yes, there is no fee to complete the TDAC.
Do children need to register?
Yes. Every traveler, regardless of age, must have a TDAC submission.
Can I register on the same day I travel?
Yes, though we recommend registering at least 24 hours in advance to avoid delays.
Do I need to print my confirmation?
No. A digital copy on your device is enough.
Do you need the THIM app for TDAC in 2026?
No. THIM is optional as of this writing. The official TDAC web portal remains valid. THIM lets you scan your passport and file your TDAC in about three minutes from a phone. In pilot since June 2026, full launch targeted for August 2026. Treat it as a faster option, not a new requirement, until the Immigration Bureau confirms otherwise. Available on iOS and Android.
What are the automated border control gates at Thai airports?
ABC gates use facial recognition to match you to your passport and TDAC on file, cutting wait time for eligible travelers. Live since March 2026 at Suvarnabhumi, Don Mueang, Chiang Mai, Phuket, and Hat Yai. No separate registration. Your TDAC data links automatically.
Can you edit a TDAC after submitting it?
Yes for travel details. No for identity details. Flight number, arrival date, and accommodation can be changed anytime before arrival using Update Arrival Card. Name, passport number, date of birth, and nationality are locked. If those are wrong, file a new TDAC.
What happens if the TDAC website is down before your flight?
Use the self-service kiosk at the port of entry. TM6 paper forms are no longer issued as a backup. If tdac.immigration.go.th is unavailable, complete the form on-site at an immigration kiosk instead. This adds time at the border, so submit online at least a day before travel when possible.
Do you need a TDAC if you are only transiting through a Thai airport
No, if you stay in the international transit area and don’t clear immigration. A layover that keeps you airside needs no TDAC. Exit the airport, collect baggage, or clear immigration for any reason, and it’s required.
