HSN/TSN: Find the key number in the vehicle registration document
The Manufacturer Key Number (HSN) and Model Key Number (TSN) indicate the exact car model. They are mainly required for car insurance, ordering spare parts and for car tax. But you can also use it to find out the right engine oil for the vehicle in question. Here we show you where the HSN and TSN are in the vehicle registration document and how you can find them out.

What is the HSN and TSN?
Insurance companies, administrative offices, workshops and vehicle owners can use the manufacturer and type code number to identify the exact vehicle model:
- HSN = Hcreatorskeynnumber (consists of 4 numbers)
- TSN = Ttypesskeynnumber (consists of 3 letters and 5 numbers)
For older vehicles up to 2005, the TSN consists only of numbers.
Example: The VW GOLF IV 1.8 GTI has the HSN 0603 and the TSN 424.
The vehicle key number is entered both in the vehicle registration document and in the vehicle registration document. You can also find out the respective HSN/TSN via the Federal Motor Transport Authority, as we show below.
