Important Information

1. The birth certificate is an important document necessary for submitting a request to register a child's name in the household register with the local registrar. This is required to obtain a person’s entry and a 13-digit ID number in the national population database. It is also related to the individual's rights and responsibilities, such as voting and applying for a passport. Therefore, the recipient of the birth certificate should check the details to ensure the information is recorded correctly. If any information is incorrect, please notify the authorities to correct it immediately.
2. In the case of a Thai national born abroad who wishes to add their name to the temporary household register to obtain a 13-digit ID number, the child’s parents, if they are not of legal age, may issue a letter of authorization for a representative to handle the matter on their behalf.
3. If the birth certificate is lost, report it to the local police, and you can request a certified copy of the birth certificate from the Royal Thai Consulate General or the Central Civil Registration Office, Department of Provincial Administration (Wang Chaiya, Nang Lerng), Nakhon Sawan Road, Dusit District, Bangkok. Telephone numbers: (02) 281-3900, (02) 281-3121.
4. If you need to request a retroactive birth certificate for a child born before 1992 to acquire Thai nationality (under Section 10 of the Nationality Act, Amendment No. 2), please fill out the form for the interview Click here.
