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.
來自刑事/警政/海巡的未知來電，語氣嚴肅，讓人緊張。
這通電話讓我感到非常不安，語氣威脅且毫無禮貌，建議大家直接掛斷。

自稱大禾建設的營造公司，說要找許世燦董事長，留了0968-675-666號碼，結果查證後發現多起類似投訴，判定為詐騙。

诈骗
來自某貸款租賃公司，聲稱是XX營造股份有限公司許董事長（0968675666）要找我司董事長，詢問具體事宜卻說不清楚，這套劇本已使用多時，每次提到找X董或財務長就顯示是租賃貸款詐騙，請換個腳本吧。
對方聲稱是宏瑞金屬，然而同一號碼兩個月前已撥過，堅稱公司老闆未要求回電，卻一直索取老闆手機。
台新銀行信貸的未知來電讓我有點疑慮，建議先核實。
此訊息來自台新銀行的信貸推廣。

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.
