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.

FAQ — Switzerland

How to verify callers in Switzerland?

Use the official company number (website/app); avoid calling back the unknown number and check in‑app messages.

Common patterns?

Delivery updates, bank callbacks, 2FA codes; robocalls, parcel/account phishing, scripted sales calls.

What to include in a report?

Caller type, purpose, date/time, and cues that guided your decision.
