    Public administrations offer electronic public services using electronic signature and advanced methods of identification or authentication based on digital certificates.

It is a reference solution to comply with the measures of identification and authentication described in Law 39/2015 of Common Administrative Procedure of the Public Administrations.

The services of the platform are applicable to all qualified electronic certificates issued by any certification service provider supervised by the Ministry of Industry, Tourism and Commerce in Spain, including DNIe certificates.

    The validation platform of the Ministry of Territorial Policy and Public Function operates as a non-intrusive service, which can be used by all the telematics services offered by the different public administrations, state, regional and local government.
