Thai ID Card and the 13-Digit Number

Typically the hospital certificate of birth, Thai ID cards of the informant and the parents, the house register the child will be added to, and the parents' marriage certificate if any. Where the father is a foreign national, the passport plus a certified translation is requested. Requirements vary by office, so call the office you will visit before travelling.

Request a replacement or a certified extract of the record of birth at the registration office that made the entry, or at another office once the record sits in the central civil registration database. Bring the ID card of the record holder or of an interested party; a power of attorney is needed if someone else attends for you.

Update the whole set: ID card, house register, passport, driving licence, bank accounts, vehicle registration, insurance policies and educational records. If any foreign document or visa is in the former name, always keep the name-change certificate with a certified translation to present alongside it — otherwise the receiving authority treats you as a different person.

Yes. The law lets spouses agree to use either spouse's surname or to keep their own. To take a foreign spouse's surname, present the marriage certificate or marriage register with a certified translation at the registration office for recording, then update the ID card and passport in that order.

Present the divorce certificate or the final judgment at the registration office to revert to your former surname, then update the house register, ID card and passport. If the divorce took place abroad, the foreign judgment or divorce record must first be legalised and recorded as a change of family status in Thailand.

Under the ID Card Act B.E. 2526 as amended, Thai nationals must apply for an ID card on reaching seven years of age, and must file within 60 days of the duty arising. A holder whose card expires must likewise apply for a new card within 60 days of expiry, or face a fine.

In many districts a replacement for a lost or destroyed card is issued at the registration office without a police report, because officials verify identity from the fingerprint and facial-image database. Some offices still ask for supporting evidence, so bring another government-issued photo document such as a driving licence or passport.

Some Thai embassies and consulates-general issue ID cards to Thai nationals overseas, provided your name is in a Thai house register and your biometric data is already in the system. Check with the mission covering your area whether the service is offered and whether an appointment is required.

No. The 13-digit number stays with the individual for life — changing a given name, a surname or a house register does not change it. That makes it the strongest link when proving that documents in an old name and a new name belong to the same person.

Present the Thai birth certificate issued by the mission, or the legalised and translated foreign birth certificate, at the registration office where the parents are registered. The registrar assigns the child a 13-digit personal ID number, which is needed for schooling, healthcare and a future ID card.

Many civil registration tasks, such as requesting certified copies, can be handled under a power of attorney with signed copies of both parties' ID cards. Matters requiring personal declaration of intent or biometric capture — ID card issuance, marriage registration and legitimation — must be done in person.

Yes, if you live in Thailand lawfully at a fixed address. Apply at the local district registration office with your passport, valid visa or extension of stay, work permit if you have one, a lease or the house owner's consent, and your TM.30 receipt. The registrar enters you in the Tor Ror 13 house book for non-Thai nationals and issues a 13-digit number starting with 6 or 8 that banks and government offices accept as your identifier.

No. Thai law lets her keep Nangsao or use Nang, and lets her keep her own surname, take her spouse's, or use both. If she does change, the registrar issues the certificate and updates the house book and ID card first; the passport is amended afterwards, in that order.

Normally the foreign marriage certificate legalized by the issuing country and the Thai embassy — or, from 28 February 2027, carrying an Apostille — plus a Thai translation certified by the Department of Consular Affairs, the Thai spouse's ID card and house book, and the foreign spouse's passport. Call the district office first, as some ask for witnesses.

You can complete the move at the destination district office alone, without returning to your former district to file a move-out notice. Bring your ID card, the house book you are joining, and the house owner's written consent with a copy of their ID. The system removes you from the previous registration automatically.

The house registration, national ID card and passport, plus record holders such as banks, Social Security and the Revenue Department. For overseas use, keep the name change certificate with a certified translation as the evidentiary link to documents issued in your former name.

File a request with the district office where the marriage was registered for a registrar-certified copy of the Kor Ror 4 record, using your ID card or passport. If the marriage was registered at a Thai embassy abroad, request it through the Department of Consular Affairs, then have it translated and the translation certified before further use.
