Finland introduces new characters in personal identity codes to meet future demand
The Finnish Digital and Population Data Services Agency has recently implemented new characters in the personal identity code system to ensure their adequacy for future needs. The first identity code featuring the new character 'Y' was issued on December 19, 2023. This update comes as a response to the limited availability of identity codes for certain birth dates under the old system. Existing identity codes will remain unchanged.
