    Lost your card? No problem Check your pay slip, look for letters from your insurer, or call your insurance provider directly — many have English-speaking support.

Quick tip: If your employer asks for your “health insurance number” before you start a job, they almost certainly mean the SV-Nummer (social security number) for payroll — not your KVNR. Check your previous pay slip first, or contact your insurer to request one.
