Everyone must have a surname.
You can change your surname in Finland in the following situations:
- You live in Finland and your data has been entered in the Finnish Population Information System.
- You are a Finnish citizen and live abroad outside Norway, Sweden and Denmark. If you live in Norway, Sweden or Denmark and would like to change your name, please contact the authorities in your country of residence.
You can apply for a change of surname with us when you want
- to change your surname
- a compound surname for yourself
- to drop a surname included in your current compound surname
- add or remove a hyphen in your current compound surname.
The initial letter in the name must be a capital and the other letters cannot be capitals (for example, Korhonen will be accepted, but not KORHONEN or korhonen). When writing the name on your application, remember to make a clear distinction between the letters that should be in upper case and those that should be in lower case.
Change of name abroad
You do not need to submit an application for a name change to us if you have had your surname changed by a decision of the authorities of another country. Instead, you can ask us to record your new name free of charge.
Changing surname upon marriage
If you want to change your surname when you get married, do not submit an application for a change of surname, but follow the instructions on the surname upon marriage page.
Notification and change of your child's name
If your child's name has not yet been recorded in the Population Information System, it is a matter of notification of the child's personal details. Instead of submitting an application for a name change, notify us of the personal details of your child according to the instructions on a different page.
The name of a minor child entered in the Population Information System can be changed using the instructions on this page.
Do the following
Select the most suitable way for you to submit an application for a name change:
1. Electronic name change service
You can only submit an application for yourself in our electronic service if you live permanently in mainland Finland and are an adult.
Strong identification is required for using the service. Please also note that the processing fee is paid when submitting the application.
Appendices cannot be attached in the service at the moment (e.g., the separate consent form), so please send us any attachments by e-mail or post.
2. Online form
Use the online form to submit your application, if
- you are a minor and you have online banking IDs
- you are applying for a name change for your minor child
- you are simultaneously applying for a change of name for several family members or both spouses
- you cannot submit an application in the electronic name change service for any other reason.
Strong identification is required for using the service. We will send you the invoice by post to your home address or Suomi.fi message service if you have enabled it. We will process your application after payment.
If consent is required for the application, the person giving consent may also sign this form.
If any of the signatures required for the application are missing, we will request them separately. The application can be processed faster if all required signatures are already there. You can also submit your consent for a change of name separately using the consent form (in Finnish) or e-mail.
3. Downloadable form
You can also use a printable online form to submit the application. Save the form on your computer before filling it out.
Send the filled-in form to us with all the signatures by post to the following address: Digital and Population Data Services Agency, P.O. Box 1003, 00531 Helsinki, or use encrypted e-mail. You will then receive the invoice by post to your home address or Suomi.fi Messages if you have enabled it.
4. Using our services at a service location
If necessary, you can fill in the application by visiting one of our agency’s service locations. However, we recommend that you primarily fill in the application online. Visiting a service location in person does not speed up the processing of the application.
