You can apply for a change of the personal data registered by SIRI.

If you received your residence permit or residency document from the Danish Immigration Service, they decide whether your personal data can be changed.

In that case you must contact the Danish Immigration Service

If you are a citizen of one of the Nordic countries and wish to change your personal data, you must submit an application to the Civil Registration Office (CPR) in the municipality where you live.

Missing information

When you get a Danish residence permit by SIRI, we register your basic personal information, including your name, date of birth, country of birth and citizenship. We get the information from the documents submitted with your application, such as your passport, Certificate of Personal Data (birth certificate) and marriage certificate.

If your date of birth cannot be identified, e.g. due to a lack of documentation, SIRI will estimate one.

Questions and answers

You can apply for a change of the following data:

  • Name

  • Date of birth

  • Country of birth

  • Nationality (citizenship)

If you need to have your personal data changed as a result of a decision or event in Denmark (if, for example, you change your name due to marriage), the civil registrar in the parish where you live must make the changes.

Once SIRI has processed your application to change your personal data, we will send you our decision. If there are grounds for changing your data, we will also send a copy of our decision to the municipality where you live and request that they make the necessary changes in the Civil Registration System (CPR).

If SIRI rejects your application to change your registered personal data, you can appeal the rejection to the Immigration Appeals Board.
