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.
他们打电话给我，我礼貌地回复说我对他们的服务不感兴趣，那个粗鲁的销售人员威胁我，如果我不听他的话，他每5秒钟就会给我打一次电话，他真的这么做了，不断地打电话给我，直到我屏蔽了这个号码，不会有人可以采取措施来对付这些骚扰电话吗
一个非意大利的女操作员打来电话，拒绝后她变得很执着
Man ruft immer wieder an, bis man ans Telefon geht, und dann wird eine Meinungsumfrage angeboten. Nach sieben Erklärungen, dass ich kein Interesse habe und nicht angerufen werden möchte, bleibt das unbeeindruckt.

我见到业不吃意这点数字说明语気上叠不这丁叠是WeChat账弅5尚不可以或老作异
È stata effettuata una chiamata appena ora. Non ho risposto poiché il numero mi è sconosciuto e non desidero partecipare al GFK (se è quello).
未知号码，未知目的，很奇怪。
Inmediatamente en la lista negra
Fui contactado varias veces por personas que no hablan bien el italiano y se hacen pasar por alguien más, además son muy descorteses, es inaceptable
Si reciben llamadas de números como este, bloquéenlos y vayan a la policía, es muy sencillo
Am Samstag um 12:30 kam ein Anruf, ich befand mich im Zug mit schlechtem Empfang. Ich teilte mit, dass ich nicht an der Umfrage teilnehmen will, und das war erledigt.
市场调查电话有时会提供有用信息，但频率太高会让人感到打扰。
销售热线，推销股票，听起来不太可靠。

Quince llamadas en dos días, no hay necesidad de agregar más pruebas

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.
