We use your data for one purpose only: filing your Thailand Digital Arrival Card with the Immigration Bureau. Your personal information is encrypted in transit, never stored on our servers after processing, and never shared with third parties.
Before you begin
Have your travel details ready before you begin.
Before you start the TDAC application form, keep your passport, arrival date, flight number, and Thailand accommodation address nearby. This assisted Thailand Digital Arrival Card service helps you avoid common mistakes by reviewing your passport and travel details before submission. We file your TDAC in the official pre-arrival window and send the approved QR code to your email before you travel, so you can arrive in Thailand with your entry document ready.
Why use assisted filing
The TDAC form is short but unforgiving. A typo in a passport number, a wrong arrival date, or the wrong occupation for a child can mean a delay at immigration.

Most foreign travellers entering Thailand by air, land, or sea need a TDAC submitted before arrival. Diplomats and some transit cases are exceptions.
The TDAC is filed inside the official 72-hour pre-arrival window. If you order earlier, we queue your application and submit it at the right time.
The fee covers human review of your details, filing your TDAC inside the arrival window, QR-code delivery to your email, family/group handling, and support if details need correcting. Travellers who prefer to self-file may use the official portal directly.
Yes. One assisted order supports up to six travellers. Each passport needs its own TDAC, including children and infants who travel on their own passport.
Choose the closest available non-working option in the TDAC dropdown — typically Child, Student, or Other depending on what is offered at the time of filing.
Email us before your arrival window opens. We can update accommodation or flight information without you starting over.
After your TDAC is filed, the approved QR code is sent to the email address on your order. Save it offline before you travel.
If we are unable to submit your TDAC for any reason on our side, the service fee is refunded.
About the Thailand Digital Arrival Card
The Thailand Digital Arrival Card, commonly written as TDAC and sometimes mistyped as TDCA, is the electronic replacement for the paper TM6 arrival form that travellers used to fill in on the plane before landing in Thailand. Since the Thai immigration authorities moved the process online, every foreign national entering the Kingdom of Thailand — by air, by land, or by sea — is required to submit a Thailand Digital Arrival Card before crossing the border. This obligation applies whether the traveller is visiting for tourism, business, transit, study, medical treatment, or to join family. Thai nationals are exempt; everyone else must file.
The card is mandatory. It is not optional, it is not replaced by a visa, and it is not satisfied by a hotel reservation alone. A traveller who arrives at a Thai immigration counter without a valid TDAC reference can be held at the border while the form is completed, and in some cases the airline is asked to verify the submission before boarding the flight to Thailand. Submitting the TDAC accurately and on time is therefore part of the basic paperwork of entering Thailand in 2026, just like a valid passport or proof of onward travel.
The form has a strict submission window: it must be filed inside the official 72-hour pre-arrival period, and it must reflect the details of the flight, vessel, or vehicle that actually lands or crosses into Thailand. The TDAC asks for passport identification, nationality, date of birth, occupation, arrival date, mode of transport with the corresponding flight number or vehicle registration, purpose of travel, and the address of the first accommodation inside Thailand. Each field needs to match the travel documents and reservations the traveller is carrying — typos in the passport number, the wrong arrival date, or an incomplete hotel address are the most common reasons applications are rejected or held for review.
Children and infants also need their own Thailand Digital Arrival Card if they travel on their own passport. Family members can be added to a single assisted-filing order so that the same arrival, accommodation, and contact information is reused across passports, which is faster than filing each passenger separately on the official portal. After a TDAC is approved, an arrival reference and QR code are issued; that QR code is what immigration officers scan on arrival, so it must be available — printed or stored offline on a phone — at the moment the traveller reaches the counter.
TDAC.info is an independent assisted-filing service. Travellers who prefer to submit the form themselves can do so at no cost through the official Thai immigration portal at tdac.immigration.go.th. Our $29 per-traveller fee covers human review of every field before submission, filing inside the official 72-hour window, QR-code delivery by email, group handling for families, and support if a flight, hotel, or other detail changes before arrival.
