Next to vehicle type data since 1st October 2019 also CoC data from the central database of certificates of conformity following § 45a of the Vehicle Registration Regulation (FZV) have been made available by the KBA for the retrieve by registration authorities
These data are technical records based on vehicle identification numbers, that describe in detail the individual vehicle. They are provided to the KBA by vehicle manufacturers and importers. The use of this dataset by the registration authorities replaces the hitherto required manual transfer of content from the submitted paper CoC. The CoC dataset is also the basis to enable the vehicle registration via internet.
