Reverse Phone Lookup in Mainland China — Recent Community Reports
Check unknown Chinese numbers with recent reports (Beijing, Shanghai, Guangzhou, Shenzhen) and share your experience.
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.

Doxa indagini di mercato的来电没有说明具体用途，让人有点困惑。
付费电话直接扣费，根本没有提供任何服务。
Aiuto.
金彩群这个名字，我已经查到。
Il sondaggio sulle abitudini di ascolto radio mi ha coinvolto volentieri per circa dieci minuti, durante un momento di inattività, perciò non mi è dispiaciuto restare al telefono. Le domande riguardavano l’ascolto delle radio italiane, il comune di residenza, l’uso dell’auto e la composizione familiare, formulate per fasce di valore piuttosto che in modo dettagliato. Ho risposto a tutto, ma è possibile omettere risposte se lo si desidera.
Cercano di stipulare un contratto usando dati falsi.

付费电话若未提前提示费用，可能造成不必要的开支。

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.
