What is it and when to act?
The eVB-Nummer is a mandatory code from your insurer — without it the Zulassungsstelle will refuse to register your car. Obtain it after signing the Kaufvertrag (you need the VIN) and before going to the Zulassungsstelle. The whole process takes 5–10 minutes online.
Where to get it
Compare prices on Check24 or go directly to an insurer (HUK, ADAC, Allianz, etc.). After payment, the eVB code appears in your online account or is emailed to you.
Common mistakes
I arrived at the Zulassungsstelle without the eVB — I had the payment receipt but not the actual code. Had to call the insurer from the waiting room. Write down the 7-character code separately and don't rely on the email.
I took out insurance with a start date one week away to 'save money'. The eVB was issued with a future start date — the Zulassungsstelle refused it: insurance must be active from the registration date itself.
