Unknown calls in Switzerland

Unsure about a Swiss number? Explore concise community notes to judge calls and texts. In Zürich, Genève, Basel, Bern and Lausanne you’ll see legitimate callbacks (deliveries, banking, appointments) and waves of robocalls or phishing. Prefixes like 044 (Zürich), 022 (Genève), 061 (Basel), 031 (Bern), 021 (Lausanne) and 07x mobile ranges are useful context but not proof of origin due to portability and VoIP.

Verification: return calls via the official number on the company website/app, check in‑app notices, and never share one‑time codes by phone. Use device/carrier blocking for repeat issues and leave a short, factual note here to help others.

Eine seriöse Marktforschung zu Radiosendern wurde durchgeführt; als festgestellt wurde, dass in meiner Region bereits genug Befragungen stattgefunden hatten, dankte der Interviewer und beendete das Gespräch.
