At a glance
For internet-based vehicle registration (i-Kfz), you need the hidden security codes on your vehicle documents and license plate seals. All Registration Certificates Part I and plate seals issued since January 1, 2015, and Part II certificates issued since January 1, 2018, feature these codes.
This guide applies to all registration offices in Altenkirchen.
1. Security code on Registration Certificate Part I (Fahrzeugschein)
On the back of your Fahrzeugschein (issued from 2015 onwards), there is a silver scratch-off field or peel-off foil covering a 7-character alphanumeric code and a 2D DataMatrix code.
2. Security codes on the license plate seals (Stempelplaketten)
For online deregistration or a license plate change, uncover the 3-character codes under the state seals on both plates:
- Peel off the colored state seal or gently scratch off the center field using a coin.
- Do not use a sharp knife or screwdriver so the code beneath remains legible.
3. Security code on Registration Certificate Part II (Fahrzeugbrief)
For new registration, transfer of ownership, or re-registration, scratch off the silver field on the bottom right of the front side of Part II (issued from 2018 onwards).

- What if the security code gets slightly damaged while scratching?
- The adjacent square 2D DataMatrix code usually remains readable. You can upload a photo in the online form so the code can be verified.
