Former surname (maiden name) notation

Inclusion of former name (maiden name) on copies of Certificate of Residence, My Number Card, seal registration certificate, etc.

With the enforcement of the ordinance to partially amend the Enforcement Order of the Basic Resident Register Act, starting from November 5, 2019, upon request from the individual, it has become possible to include the former surname (the surname recorded in the family register, family register extract, certificate of removal, and extract of removal) alongside the current surname on the Certificate of Residence, My Number Card, and seal registration certificate.

Documents that can include the former name

• Copy of Certificate of Residence
• Certificate of Residence Details Certificate
• Seal Registration Certificate (You can also register a seal with a former name.)
• My Number Card
• Electronic Certificate for Signature of Public Personal Authentication Service

• Note: When registering a former surname, the former surname will be listed on all of the above [Documents where former surname can be included]. (It is not possible to display only one of either the former surname or the current surname on the family register.)
• Note: Foreign nationals cannot include their former surname.

Former surnames that can be listed together

Registration

• Only one former surname can be listed for each person.
