EC type approval number, sales type and sales/trade names
Since 1 January 1998, all passenger vehicles licensed for road use within the European Union must have a type approval in line with EU guidelines; vehicles licensed for road use with a single vehicle approval according to § 21 StVZO in Germany are excluded from this regulation.
This means the same guidelines apply to all automobile manufacturers. As a consequence, international trade within the EU has become easier.
The COC paper contains the EC type approval number and comprehensive technical vehicle data such as the emission class and all permissible wheel/tyre combinations.
