Health insurance certificate (Krankenversicherungsnachweis)
An official document from your insurer confirming that your health insurance coverage is valid.
What it means in plain English
Health insurance certificate. An official document from your insurer confirming that your health insurance coverage is valid.
Common confusion
This is the proof document, not the insurance policy itself. Authorities and universities often want the formal confirmation from your insurer, not just a card, screenshot, or payment receipt.
