Unknown calls in Mainland China
Unsure about a number from mainland China? Explore concise community notes to judge calls and texts. In Beijing, Shanghai, Guangzhou and Shenzhen you’ll see both legitimate callbacks (deliveries, banking, appointments) and waves of robocalls or phishing. Prefixes like 010 (Beijing), 021 (Shanghai), 020 (Guangzhou), 0755 (Shenzhen) and mobile 13x/15x/18x ranges 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.
Alle 21:00 è stata effettuata una chiamata, non ho risposto. Fastidioso.

Debt Collector
这个号码打来的讨债公司电话，感觉很紧张，不想接听。
J'ai reçu deux appels manqués de ce numéro, puis deux autres appels une heure plus tard, que j'ai rejetés, et j'ai immédiatement bloqué le numéro, car ils sont trop insistants et m'envahissent d'appels

Robocall
Sono stato chiamato alle 4 del mattino, probabilmente era un tentativo di ping call con una prefisso sconosciuta!!
自称是CIBANCO的讨债公司，感觉不太真实。
Credit Agricole的电话，内容挺有用，值得信赖。
这个人似乎没有什么正经事做，总是打电话过来
Intrusive and persistent calls have been made
Die Telefonnummer wurde sofort abgewiesen; bei Fragen wurde viel zu schnell weitergeleitet, sodass man nichts notieren kann. Der Fragebogen war miserabel – vielleicht war der Interviewer nicht geschult? Ich brach nach fünf Minuten ab. Sehr nervig.
Es recomendable bloquear este número, ya que llaman de manera insistente
Sono chiamate che disturbano senza uno scopo, meglio bloccarle
Comercio en línea
交易公司的付费电话，感觉还挺正常的。
trading online的销售热线，推销产品，有点烦。
Una telefonata da un call center straniero con un operatore molto scortese, non si riusciva a capire cosa stesse dicendo, appena ho capito che era una solita telefonata di trading, ho detto di non essere interessata e mi hanno riattaccato in faccia, pertanto va inserita nella lista nera.
未知号码打来，又是推销广告，真是烦人！
trading online 的付费电话，感觉没什么用。

FAQ — China
How to verify callers in China?
Use the official number from the website/app; avoid calling back the unknown number and check in‑app messages.
Do prefixes prove location?
No. Portability/VoIP make 010/021/020/0755 and 13x/15x/18x 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.
