Publication date 27.2.2023 11.17 | Published in English on 1.3.2023 at 12.44
Press release

The electronic ID cards issued by the police are renewed. In connection with this change, the Digital and Population Data Services Agency will renew the technology behind the citizen certificate that is on the electronic ID card’s chip, to ensure that the certificate can continue to be used easily and securely also in the future. The electronic ID card’s activation PIN letter will also be renewed. These changes will apply to electronic ID cards issued on or after 13th of March 2023.

In the renewed activation PIN letter, the activation PIN required for activating the citizen certificate will no longer be printed on a plastic strip. Instead, the PIN will be available on the front bottom right corner of the second page of the two-page letter. 

The renewed letter will include activation instructions in Finnish, Swedish and Northern Sámi. For activation instructions in English, please visit the Digital and Population Data Services Agency’s website at
