Since 15.07.2017, the ID card has been issued as standard with an activated online ID function (also known as the eID function) to persons aged 16 and over; since 01.01.2021, EU citizens and nationals of the European Economic Area aged 16 and over can receive eID cards with an electronic proof of identity function. An activated eID function and PIN are required to be able to identify yourself online to companies and authorities.

The one-time PIN (contained in the PIN letter that is handed out when the application is made at the authority) can be replaced with a personal PIN when the document is handed out at the authority or by the person concerned themselves on their smartphone or at a citizen terminal. The online ID card is then ready for use.

If your PIN has been set but forgotten or the PIN letter has been misplaced, you can contact any ID card or eID card authority (e.g. citizens' office, town hall). If the online ID function has not yet been activated, you can contact the issuing or responsible ID card or eID card authority.
