Natural persons who wish to cancel your valid qualified certificate for electronic signature (digital certificate) of the Greek State Certifying Authority (APEA) that you hold should follow the relevant instructions for the withdrawal of a certificate for electronic signature of the CADD. This service should only be used for the revocation of an electronic signature certificate of the APDD issued since 17/1/2022, and only if the mobile phone number registered at the time the electronic signature was issued has changed and you do not remember the issue/revocation code. To issue the self-declaration of withdrawal you will need:

• either your web banking codes or your personal Taxisnet credentials (after registering in the National Communication Register (EMEP) to confirm your mobile phone number)
• your mobile phone where confirmation codes will be sent to you before the document is issued

The process of revoking the digital certificate should continue with the submission of the online revocation request in the APED Certificate Management Application .
