The username that appears in the box when logging in to eZPIZ is automatically read from the data of the digital certificate (e-mail address through which you downloaded the digital certificate). This information cannot be changed.
If you want to receive notifications to another e-mail address, you must submit an eApplication. When you are logged in to eZPIZ, select "eApplication submission" in the menu and then fill in the application "IT-EPOSTA - APPLICATION FOR CHANGE OF E-MAIL ADDRESS THROUGH EZPIZ". You digitally sign and submit the application.
In cases where you have downloaded the digital certificate to one e-mail address, only one user can be registered at a time. These cases will be resolved through authorization, which is still under development.
