The documents needed for a Thai passport depend on your age, whether it is your first passport or a renewal, and where you apply. Applications for children also depend on parental consent and custody arrangements.
This guide explains the main points to check before booking an appointment in Thailand or the UK.
Need Help Preparing Your Documents?
Tell our Thailand office the applicant’s age, where they will apply and whether they already hold a Thai passport. We can discuss available document assistance.

For a straightforward adult application, the original Thai national ID card is normally the principal identity document. Bring your existing passport if renewing and check the chosen office’s current checklist.
Additional civil-registration evidence may be needed after a name change, marriage or a discrepancy in official records. Ensure your details are consistent before attending.
The Department of Consular Affairs publishes separate document guidance for applicants aged 20 and over and those under 20.
Thai Passport Applications for Children
Prepare the child’s Thai birth certificate, existing passport if applicable, Thai ID card where required, and the parents’ identification. House-registration evidence and documents relating to consent or custody may also be required.
Confirm the checklist for the child’s age and circumstances. Both parents normally need to provide consent, but the supporting evidence differs where a parent cannot attend or only one person has parental authority.
What If One Parent Cannot Attend?
Contact the passport office or embassy before booking. Depending on the circumstances, it may require an officially witnessed consent document, custody evidence, a court order or a death certificate.
Do not assume that a privately signed letter is sufficient. Explain the family circumstances clearly and ask which documents will be accepted.
Applying for a Thai Passport in the UK
Thai nationals in the UK should use the Royal Thai Embassy London’s passport guidance and appointment system. The embassy requires an appointment; passport walk-ins are not permitted.
Its checklists distinguish adult renewals, minor renewals and first applications. Requirements can include the current passport, Thai ID, application form and additional civil documents.
For children born abroad without a Thai birth certificate, birth registration through the appropriate Thai embassy or consulate must be addressed before the passport application.

Do Applicants Need to Attend?
Plan for the applicant to attend for identity checks and biometric capture. Document assistance does not replace attendance required by the issuing authority.
Confirm parental attendance and any authorised accompanying-person arrangements for a child.
Fees, Delivery and Travel Plans
Check the issuing office’s current fee, payment method and collection or postal arrangements when booking. Processing in Thailand and through an overseas embassy can differ.
Allow time for document corrections and delivery. Avoid relying on an assumed passport arrival date when making travel arrangements.
