What is type approval (field 24) on the Swiss vehicle registration certificate?

Type approval (in German: Typenschein or Typengenehmigung) is the official Swiss homologation system managed by FEDRO (Federal Roads Office). Every vehicle — car, motorcycle, truck — authorised to drive in Switzerland receives a 6-character type approval number (e.g. 1TD812), recorded in field 24 of the vehicle registration certificate (Fahrzeugausweis). This number provides access to the complete approval sheet: dimensions, authorised weights, engine, displacement, power, fuel type, emission standards, approved wheels and tyres, and all approved variants. SwissCarInfo allows you to view these approval sheets online using the field 24 number.

Where can I find the type approval number on my registration certificate?

The type approval number is found in field 24 of your Swiss vehicle registration certificate. It consists of 6 alphanumeric characters, for example 1TD812 or 1BA801. On older certificates, it may appear as a 6-digit number such as 000101. If your field 24 shows 'IVI' or 'IVIX', your vehicle was registered via the European Certificate of Conformity (eCOC): in this case, use the registration number in field 18 to search on SwissCarInfo.

How to search for technical data of a Swiss vehicle online?

On SwissCarInfo, you have several methods to find the technical data sheet of a vehicle registered in Switzerland. The most precise method is searching by type approval number (field 24 of the registration certificate). You can also search by chassis number (VIN), European approval number (e1*, e9*, e4*...), or by make and model. Results include official technical data: weight, dimensions, engine, consumption, CO2 emissions, approved wheels and tyres, and much more.

What does IVI or IVIX mean in field 24 of the registration certificate?

Some vehicles registered in Switzerland via the electronic European Certificate of Conformity (eCOC) show 'IVI' or 'IVIX' in field 24 of the registration certificate, instead of a standard type approval number. IVI stands for 'Individual Vehicle Registration'. IVIX is identical, but the 'X' indicates that the importer has declined publication of certain technical data. For these vehicles, SwissCarInfo uses the registration number from field 18 to retrieve the complete technical data from the European database.
