If you lose your identity card or temporary identity card, you are obliged to inform the identity card authority of your (residential) municipality immediately. An identity check is required there.

The identity card authority must also be notified if your identity card is found again and the previously lost identity card must be presented. As a new document is usually issued, this is essential, also to prevent problems when using these identity documents.

If a criminal offense is involved, contact the local police station (see "Reporting a criminal offense to the police" under "Related topics").

If a report is not made to the ID card authority or not made in good time, an administrative offense is committed which can be punished with a fine.

In order to prevent misuse, the ID card holder must immediately report the loss (loss, theft) of the ID card to the blocking hotline (116 116) or to the ID card authority to block the online ID card function (see "Related topics").

If you have also applied an electronic signature to the ID card, you must have the signature function blocked separately. To do this, please contact the provider from whom you purchased the signature certificate and report the loss to them. Neither the revocation hotline nor the ID card authority can block the signature function.
