CoC documents serve as proof of a vehicle meeting the legally defined safety and environmental compatibility standards. Every vehicle manufacturer must first obtain type approvals from the EU authorities for each vehicle type it produces.
Subsequently, a Certificate of Conformity needs to be created and issued for each vehicle of each approved type as a prerequisite for the following registration procedures. In light of the considerable administrative burden this process entails, paper CoCs are gradually being replaced by electronic documents.
An electronic CoC (IVI) is a digital data record in XML format that contains exactly the same information as the paper-version of a CoC - including all necessary technical details and values of the vehicle in question, such as dimensions, weight, fuel consumption and emission values.
