A system for examining service certifications with multi-sides based on customer experiences is provided, including: a database, an analysis processor, a certification system, an accreditation system, a registration system for a certification officer to register, an internal system of a service firm and a mobile terminal. A first time certification is performed on services from the service firm by the certification system to obtain a service certification credential. A first QR code is identified to obtain an organization name of the certification organization, basic information of the service certification credential, accreditation information of the accreditation system, registration information of the certification officer registered in the registration system and authorization information, authorized by the Certification and Accreditation Administration, for carrying out service certification businesses of the certification organization. After a second QR code is identified, the mobile terminal is linked to a customer experience collecting interface via the database.
