Checked against the official Thailand Digital Arrival Card guide and FAQ on October 6, 2026.
Thailand's Digital Arrival Card creates a new routine for repeat visitors: one arrival-card submission for each entry, then a separate record of what actually happened at the border.
Short answer: the Thailand Digital Arrival Card, or TDAC, is an online arrival-card form for non-Thai nationals entering Thailand by air, land, or sea. The official FAQ says it can be submitted within 3 days before arrival, including the arrival date, and that it is valid for one-time use on the expected arrival date. TDAC is not a visa, not a tax-residency rule, and not your allowed-stay clock.

What is Thailand's TDAC?
The Thailand Immigration Bureau says TDAC is an online form that replaces the traditional paper-based arrival card for international travelers entering Thailand.
The official guide says TDAC applies regardless of transportation mode. That means land, air, and sea arrivals are in scope.
For recordkeeping, treat TDAC as arrival paperwork. It belongs beside your entry record, not inside your visa-status logic.
Who needs to submit TDAC?
The official guide says all non-Thai nationals entering Thailand must complete TDAC online before entry.
The FAQ says the same rule applies whether the traveler arrives by land, air, or sea. It also says infants and children need TDAC, diplomatic passport holders need it if they are non-Thai nationals, and crew members do not need it.
If you are transiting, the FAQ gives a practical split:
| Situation | TDAC needed? |
|---|---|
| Technical landing or transit flight | No TDAC needed |
| Transit without passing through immigration | No TDAC needed |
| Leaving the airport | TDAC needed |
| Entering Thailand by land, air, or sea | TDAC needed for non-Thai nationals |
Use the official FAQ for the current version before travel. Border forms can change faster than personal travel checklists.
When should you submit TDAC?
The FAQ says TDAC should be submitted within 3 days before arriving in Thailand, including the arrival date. It also describes the window as up to 72 hours before entry.
Do not read that as "exactly 3 days before." The safer tracking language is "within 3 days before arrival, including the arrival date."
For repeat travelers, set up a simple pre-arrival reminder:
- check arrival date
- prepare passport and trip details
- submit TDAC within the official window
- save the QR code or downloaded document
- record the Thailand entry date after arrival
TDAC does not send reminders. If Thailand is one stop in a busy travel week, the reminder has to come from your own calendar or tracking workflow.
What information should you prepare?
The official FAQ says TDAC asks for:
- passport details
- flight number and arrival date
- address in Thailand
- travel purpose
- health declaration information
- email address to receive the TDAC
The official guide also groups the required information into passport, personal, travel, accommodation, and health declaration details.
This is not hard if the information is ready. The FAQ estimates about 3 to 5 minutes per person. It becomes messy when you try to do it from scattered emails at the airport.
Can you update TDAC after submission?
Some information can be updated, but not everything.
The official guide says full name, nationality or citizenship, and date of birth cannot be updated after submission. The FAQ also lists passport number among details that cannot be updated, and says that if a mistake cannot be corrected, travelers should submit a new form with the correct details. The latest valid submission will be used.
For tracking, keep the final TDAC record, not every abandoned version.
Save:
- TDAC number or confirmation record
- final submitted arrival date
- email used
- QR code or downloaded document
- any correction notes
- the actual entry date after arrival
Is TDAC a visa?
No. The official guide says the Thailand Digital Arrival Card is not a visa.
That is the most important boundary in this guide.
TDAC can sit beside different entry types. The FAQ says it is compatible with all visa types, including visa-on-arrival and visa-exempt entries. That does not mean TDAC replaces visa requirements, extends a stay, or decides how long you can remain in Thailand.
If you are tracking a Thailand visa or stay period, keep that record separate from TDAC. For example, Thailand DTV holders should track the DTV stay period separately from arrival-card paperwork. See our guide to Thailand DTV 180-day stay tracking for that separate stay-clock issue.
Does TDAC affect Thailand tax residence?
No source in the approved research pack says TDAC changes Thailand tax residence.
TDAC is arrival paperwork. Thai tax residence is a separate tax question, and Thailand visa or entry permission is a separate immigration question.
If you need the tax side, keep a country-day record and use tax-specific sources. For the separate income-tax context, see our guide to Thailand foreign income tax in 2026.
Do not make TDAC do work it does not do. It is not your tax-residency rule, your visa, or your stay-permission counter.
What should repeat travelers track for each Thailand entry?
For each Thailand entry, keep the TDAC record and the actual travel record together.
Track:
- intended arrival date
- TDAC submission date
- email used for TDAC
- TDAC QR code or downloaded document
- final TDAC version if you update or resubmit
- passport used
- visa type or visa-exempt entry note, if relevant
- actual Thailand entry date
- actual Thailand exit date
- accommodation address used in the submission
- any website-error screenshot or staff instruction, if relevant
- source-check date for the official TDAC guide or FAQ
This is especially useful for people who enter Thailand often. TDAC is one-time use, so yesterday's arrival card is not the record for your next trip.
Where Jetseen fits

FAQ
Is TDAC required for every Thailand entry?
The official FAQ says the Thailand Digital Arrival Card is valid only for one-time use on the expected arrival date, and travelers must submit a new TDAC every time they enter Thailand.
Can one TDAC cover multiple people?
The official guide says group submission can include up to 10 entries per submission. Keep a copy of the final record for each traveler in the group.
Do I need to print TDAC?
The FAQ says travelers do not have to print it, but they should download the document with the QR code after submitting or from email. It also says printing a copy is a good idea if the traveler will not have a device.
Can Jetseen submit TDAC for me?
No. Use the official TDAC site for submission. Jetseen can help you track Thailand entry and exit dates, notes, documents, reminders, and CSV records.
