Travelling to Thailand with family or friends? Each person still needs a TDAC. The official form lets you add other travellers so you do not have to start over every time.
Short answer
Every non-Thai traveller needs a TDAC, including children and babies. The official portal offers an individual option and a group option. Travel guides report the group option covers up to 10 people, but confirm the current limit on the official site because it can change.
What you need for each person
- Passport details exactly as printed, including the number and expiry date.
- Nationality and date of birth.
- Flight details for arrival, and the first accommodation address in Thailand.
- An email address where the confirmation can be sent.
Tips for families
- Collect all passports in one place before you start, so you do not mix up numbers.
- Check every name against the passport, especially for children whose passports may use a different spelling.
- Submit when the 3-day window opens for the shared arrival date.
- Save a confirmation for every traveller and keep it on one phone as well as a backup.
Common mistakes
- Assuming a child on a parent's passport does not need a card.
- Using a different arrival date for one person in the group.
- Paying an agent because a group form looks complicated. It is free on the official site.
Questions and answers
Do children need a TDAC?
Yes. Every non-Thai traveller, including children, needs their own entry on the card unless an official exemption applies.
How many people can I add to one group submission?
Travel guides report up to 10 people. Check the official site for the current limit.
Do we all need the same arrival date?
A group submission is meant for people arriving together. If someone arrives on a different date, submit a separate card for them.
