Unknown calls in the Czech Republic

Unsure about a Czech number? Explore concise community notes to judge calls and texts. In Praha (Prague), Brno, Ostrava and Plzeň you’ll encounter both legitimate callbacks (deliveries, banking, appointments) and waves of robocalls or phishing. Geographic prefixes and mobile ranges (e.g., 2x/3xx/5xx, 60x/77x) are useful context but not proof of origin due to portability and VoIP — treat them as helpful hints, not certainty.

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 so others can benefit.
