Unknown calls in Poland
Unsure about a Polish number? Explore concise community notes to judge calls and texts. In Warszawa, Kraków, Wrocław, Poznań and Gdańsk you’ll see both legitimate callbacks (deliveries, banking, appointments) and waves of robocalls or phishing. Prefixes like 22 (Warsaw), 12 (Kraków), 71 (Wrocław), 61 (Poznań), 58 (Gdańsk) and mobile ranges (5/6/7) are helpful context but not proof of origin due to portability and VoIP.
Verification: return calls via the official number on the provider’s website/app, check in‑app notices, and never share one‑time codes by phone. Use device/carrier blocking for repeats and leave a short, factual note here to help others.

FAQ — Poland
How to verify callers in Poland?
Use the official website/app number and check in‑app messages; avoid calling back the unknown number.
Do prefixes prove location?
No. Portability/VoIP make 22/12/71/61/58 and mobile ranges unreliable as proof of origin.
Common patterns?
Delivery updates, bank callbacks, 2FA codes; robocalls, parcel/account phishing, scripted sales.
What to include in a report?
Caller type, purpose, date/time, and cues that guided your decision.
