Possible ways for the identity verification


Application for a User Certificate

User Certificates issued by the DFN-PKI Global contain the applicant's first and last name in the field "Common Name". Consequently, it is necessary to formally check the identity of the applicant. There are currently two different procedures for identity verification:

  1. In person at the IT-ServiceDesk.
  2. In person at the ZHV-Helpdesk, if you are a ZHV employee.

In both cases you need to show a valid identity document (alongside your signed request).

Accepted identity documents are passports, identity cards and German residency permits. Beware: Drivers licences are not accepted as an identity document.

Application for a Group Certificate

  • Bring the application in person to the IT-ServiceDesk or the ZHV-Helpdesk (for ZHV employees). Verification of the applicants' identity is based on a valid identification document.
  • Send the hand-signed application in a digitally signed (and preferably encrypted) e-mail to
  • Please note:
    • the digitally signed e-mail needs to be sent from your personal email account, we can only verify your identity if the corresponding DFN-PKI user certificate has been issued for "CN=Firstname Lastname".
