Change Your Name in Thailand

Application at District Office (อำเภอ / สำนักงานเขต)

Submit your name change application (คำขอเปลี่ยนชื่อตัว/นามสกุล) at your local district office. You must provide grounds for the change. Thai law permits name changes for marriage, spiritual/auspicious reasons, or court-ordered changes. Bring your national ID, house registration document (ทะเบียนบ้าน), and supporting documents.

House Registration Update (ทะเบียนบ้าน)

Once your name change is approved, update your household registration document (ทะเบียนบ้าน) at the district office. This is a critical record used by all government institutions.

New National ID Card (บัตรประชาชนใหม่)

Apply for a replacement National ID card at your district office using your updated house registration and name change approval document.

Passport — Department of Consular Affairs

Apply for a new Thai passport at the Department of Consular Affairs (กรมการกงสุล) with your updated National ID card and house registration. Walk-in and appointment options available.

Driver's Licence — Department of Land Transport (DLT)

Visit a DLT office with your updated National ID to have your driving licence reissued in your new name.

Social Security Office (SSO)

Notify the Social Security Office (สำนักงานประกันสังคม) of your name change. This affects your social security contributions and benefit records.

Revenue Department — Tax Records

Update your tax identification and personal income tax records with the Revenue Department (กรมสรรพากร) using your updated ID documents.

Banks & Financial Institutions

Visit each bank branch with your updated National ID and house registration document to update all accounts. Major Thai banks (Bangkok Bank, Kasikorn, SCB, Krungthai) all require in-person updates.
