Citizen Certificate and electronic identity

The Citizen Certificate is a form of electronic identification to help identify someone reliably when they are using electronic services. Among other things, it contains a first name, a last name and an electronic client identifier. An electronic Unique Identification Number (SATU) serves as the person’s unique identifier in the certificate.

The Citizen Certificate is contained in the personal identity card

In Finland ID cards are issued by the police and abroad by Finnish consulates. The Citizen Certificate stored on an ID card allows

  • people to identify themselves electronically, for example, when accessing the e-services of authorities
  • encrypt emails
  • encrypt documents
  • create an electronic signature.

For the Certificate to be used for e-services it first has to be activated.

You can use your ID card as a form of personal identification and as a travel document, and the Citizen Certificate stored on it can be used for e-services. If you do not intend to use the Citizen Certificate for e-services, the Certificate does not need to be activated.

A Citizen Certificate may only be issued to a Finnish national or a foreign national who is resident in a Finnish municipality as referred to in the Act on the Municipality of Residence (201/1994), whose details are stored in the Population Information System and whose identity has been reliably established. The foreign national must also either hold a valid residence permit or card or his/her right of residence must have been registered.
Using the Citizen Certificate

In addition to the ID card, to use the Citizen Certificate to access services you will also need the following:

  • a computer
  • a card reader
  • card reader software
  • PIN/access codes

You create your PIN/access codes yourself when you activate the certificate.

You can download the card reader software from the card reader software web page.

Electronic transactions using the Citizen Certificate are secure. An electronically signed document is as legally binding as one signed by hand. Electronic signatures created using the Certificate on an ID card are still valid even after the card has expired.


Identification and signature certificates issued by the Digital and Population Data Services Agency meet the requirements under Regulation (EU) No 910/2014 and the Act on Strong Electronic Identification and Electronic Signatures (617/2009). The aim is to ensure high standards of information security and accurate identification in e-services. The Digital and Population Data Services Agency is a provider of an identification service that satisfies the requirements for high standards in its production of certificate-based identification tools. The Agency is, Finland’s first and, for now, only provider of signature certificates that are of an acceptable standard. The Finnish Communications Regulatory Authority oversees the work of the CA.
