This part of ISO 24534 provides requirements for electronic registration identification (ERI) that are based on an identifier assigned to a vehicle (e.g. for recognition by national authorities) suitable to be used for: - electronic identification of local and foreign vehicles by national authorities; - vehicle manufacturing, in-life maintenance and end-of-life identification (vehicle life cycle management); - adaptation of vehicle data (e.g. for international resales); - safety-related purposes; - crime reduction; - commercial services. It adheres to privacy and data protection regulations. This part of ISO 24534 defines the operational requirements for the remaining parts of ISO 24534 and the more limited but relevant provisions of ISO 24535. Whilst the definition of the organizational framework required to implement, operate and maintain an ERI system is outside the scope of this part of ISO 24534, a list of potential stakeholders in the public and private sector has been included.
