Unknown calls in Taiwan
Unsure about a Taiwanese number? Explore concise community notes to judge calls and texts. In Taipei, Kaohsiung, Taichung, Tainan and Hsinchu you’ll see both legitimate callbacks (deliveries, banking, appointments) and waves of robocalls or phishing. Prefixes like 02 (Taipei), 07 (Kaohsiung), 04 (Taichung), 06 (Tainan), 03 (Hsinchu) and mobile ranges 09xx are useful context but not proof of origin due to portability and VoIP.
Verification: return calls via the official number listed on the provider’s 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 — Taiwan
How to verify callers in Taiwan?
Use the official number from the company website/app; avoid calling back the unknown number; check in‑app messages.
Do prefixes prove location?
No. Portability/VoIP make 02/07/04/06/03 and 09xx ranges unreliable as proof.
Common patterns?
Delivery updates, bank callbacks, 2FA codes; robocalls, parcel/account phishing and scripted sales.
Helpful report details?
Caller type, purpose, date/time, and cues that guided your decision.
