TDAC Thailand 2026:Your Digital Arrival Card in 5 minutes

The problem: The field asks for your full name as it is in your passport. Travellers type a short name, leave out a middle name, or swap the family name and the first name. The update function cannot change the name later.

How to avoid it: Copy the name from the two lines of letters at the bottom of the passport photo page (the MRZ). Family name goes in the family name field. If you have no family name, the form accepts a dash (-).

The problem: The portal can read your passport data from a camera scan or a photo of the MRZ. The official user guide asks you to recheck the data every time you use this function.

How to avoid it: After the scan, compare every field with the passport, letter by letter, before you continue.

The problem: Letters and digits that look alike, such as O and 0 or I and 1, are easy to mix up. The official FAQ lists the passport number among the details you cannot update.

How to avoid it: Read the number from the passport photo page, not from an old booking or a copy. If it is wrong after you submit, file a new card. The latest submission is the valid one.

The problem: The card is for one arrival on one date. You submit it within 3 days before you arrive, counting the arrival day. A date one day off, or a card made for an earlier trip, does not match your entry.

How to avoid it: Enter the date your flight lands in Thailand, in Thai time, not the date you leave home. File a new card for every trip.

The problem: The field is Flight No./Vehicle No. With a connection, travellers often enter the first flight from home instead of the flight that lands in Thailand.

How to avoid it: Enter the number of the last leg, the one that arrives in Thailand. Check the airline code and the digits against your ticket.

The problem: The accommodation section asks for the type of stay, province, district, sub-district, post code and address. Travellers enter only a hotel name, or pick a district that does not match the address.

How to avoid it: Copy the full address from your booking confirmation. The address line takes up to 215 characters, so there is room for the property name, street and number.

The problem: All details must be in English. Some travellers type their occupation or city in their own language or script.

How to avoid it: Use a plain English word for your job, for example TEACHER or ENGINEER, and English spelling for place names.

The problem: The card and its QR code go to the email address you enter. One wrong letter and nothing arrives.

How to avoid it: Check the address twice before you submit. If the email does not arrive, the official advice is to contact the immigration officer at the entry checkpoint.
