Changing surname

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. 

How to notify us of a name that has been changed abroad

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.

Price

The processing fee for the application for a change of forename is EUR 95 per change of name or per person applying for it

How we process your application 

1. Submitting the application 

Use the instructions below to apply.  

We will not send a separate message to acknowledge receipt of your application. 

2. Processing the application 

We will not start processing your application until you have paid the processing fee. We will process the applications in the order we have received them. Applications that have been paid directly in connection with applying may therefore progress faster. Please note! The fee will not be returned even if you cancel your application, or we reject the application. 

We may ask you to provide additional information about the name you would like to adopt or any missing documents. Sometimes we also request an opinion from the Names Board. In that case, it will take longer to process your application.  

Unfortunately, you will not be able to monitor the progress of your application. However, you can find the average processing time on this page.  

3. Resolution of the case 

Once we have processed your application, you will receive a written decision by post, email or Suomi.fi Messages if you use the service. Your new name will be entered into the Population Information System on the day the decision is made, if the name you have applied for is approved.  

After the name has been changed, you will automatically receive a new Kela card in the post. However, you will have to renew your passport, electronic ID card and driving licence in your new name yourself.  

If you are not satisfied with the decision, you have the right to appeal against it to an Administrative Court.
