To use an electronic certificate, it is necessary to have a certificate issued by a service provider recognised by the Administration (e.g., the Police, FNMT, Camerfirma, etc.). For example, certificates issued by certification authorities from other countries are not valid.

Likewise, the certificate must be valid, that is, it must not be expired or revoked. The expiry of the certificate can be directly verified by the user (the end date of validity appears on the certificate itself), however, the revocation status cannot.

A certification authority automatically revokes a certificate when a new one is generated for the same person. In the case of certificates for a public employee, if the person holds a position reflected in the certificate (e.g., department director, director, etc.), this may be revoked upon leaving the position.
