Planning a family trip to Thailand requires careful planning, especially when traveling with children.
This guide breaks down everything you need to know about Thailand’s entry requirements for children, including the Thailand Digital Arrical Card (TDAC) policy.
Thailand’s Mandatory Entry Documents for Children
When traveling to Thailand with kids, every child must meet the entry requirements individually. This is regardless of age.
Essential documents for each child:
- Valid passport (minimum 6 months validity)
- Completed TDAC (Thailand Digital Arrival Card)
- Approved Thailand visa (if required)
- Proof of onward or return travel
- Accommodation details (hotel or address in Thailand)
Important: Even infants need their own passport and travel authorization.
Completing the Thailand Digital Arrival Card (TDAC) for Children
The Thailand Digital Arrival Card (TDAC) is mandatory for all travelers, including minors.
Important note: The TDAC replaces the previously planned ETA. You only need a TDAC, as the ETA does not exist.
How it works for families:
- Parents can submit TDACs on behalf of children
- Each child must have a separate application
- Information must match the passport exactly
Tip: Submit all family TDACs at the same time to avoid inconsistencies at immigration.
Thailand Required Documents for Solo Parents or Guardians
Traveling with only one parent or as a guardian requires additional documentation. This is one of the most common reasons families face delays.
You may need:
- Notarized parental consent letter
- Birth certificates and proof of relationship
Find out more below.
Notarized parental consent letters
If a child is traveling with:
- Only one parent
- A legal guardian
- Another adult (e.g., grandparents)
You should carry a notarized consent letter from the non-traveling parent(s).
The letter should include:
- Child’s full name and passport details
- Names of both parents
- Travel dates and destination (Thailand)
- Signature of the non-traveling parent
- Notary certification
Important: Airlines in the U.S. may request this before boarding, not just at Thai immigration.
Birth certificates and proof of relationship
Carry supporting documents to prove your relationship to the child:
- Birth certificate (showing parents’ names)
- Adoption papers (if applicable)
- Custody documents (if relevant)
These are especially important if surnames differ.
Thailand’s Financial Requirements for Families
Thailand requires proof of financial means upon entry. For families, this should be a minimum of 20,000 THB (~$600 USD).
Can be shown via:
- Cash
- Bank statements
- Credit cards (supporting evidence)
Immigration officers may not always ask, but you must be prepared.
Health & Vaccinations: Entry Rules vs. Recommendations
Currently, Thailand has no mandatory vaccinations for most travelers.
However, these are recommended for families:
- Example Item
For young children, bring basic medications and check pediatric care availability at your destination.

FAQs for Traveling to Thailand With Kids
Here are some of the most common questions from families:
Can children use an emergency passport to enter Thailand? Toggle faqs
That depends on the passport type and the airline’s policy. Some emergency or temporary passports can create issues with pre-travel authorization systems or boarding checks.
Families should verify passport policies well in advance before traveling.
Do adopted children or children with a different surname need extra documents? Toggle faqs
When a child’s surname does not match the accompanying parent’s, it’s highly recommended to carry supporting documents that clearly explain the relationship. This helps avoid confusion at check-in or immigration.
Should parents keep all family travel documents together or separately? Toggle faqs
It’s best to do both: keep one main folder with everyone’s documents, but also save each child’s records separately in digital form.
Covering both options makes it much easier to find the right file quickly if an airline or immigration officer asks for one child’s details only.
Is it a good idea to translate family documents into English? Toggle faqs
Yes, especially if original documents are in another language.
While not every document will be requested, having an English version of key family papers can make checks smoother and faster.
What is the most common mistake families make with children’s travel paperwork? Toggle faqs
One of the biggest issues is assuming a child can be processed under the parent’s documents without needing separate attention.
In practice, children’s details often need to be checked just as carefully. Families should review each child’s information separately before traveling.
