No, it is not possible to modify an IdCAT Certificate once it has been issued. The digital certificate is an electronic document that guarantees your identity in online procedures, and any change to its data would break its integrity and validity.

This is because the certificate is digitally signed by the certifying entity, and any alteration would make it no longer reliable for the administrations and services that recognize it.

If your details have changed (for example, name, ID or address) you will need to:

  • Revoke the current certificate .
  • Request a new one with the correct details
