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.
市场调查的电话态度友好，但问卷太长，稍显打扰。
Meglio non rispondere, tipo!

未知
未知来电没有任何提示，最好先确认再回拨。
收到一条来自未知号码的诈骗短信，声称中奖了，要求提供个人信息。幸好我没上当，赶紧拉黑了。真是太可恶了，这些骗子到处都是。
这个号码打进来只是ping通话，没有任何声音或内容，就挂断了。感觉像是网络测试或什么的，没造成什么影响。
Solo due squilli e poi fine, è spam (con rischio di perdere credito telefonico/Ping Call). Dopo aver visto il credito scendere, ho smesso di chiamare questi numeri, mah.
Suona due volte e poi si interrompe.
Ping通话的来电没有任何价值，直接忽略吧。
Si tratta dell’assistenza di Open Fiber, che contatta per fissare gli appuntamenti di attivazione della fibra ottica. Il numero è legittimo, potete rispondere. Tuttavia non è richiamabile: la chiamata rimane in attesa indefinita e non viene mai risposta; Open Fiber utilizza solo un modulo online, con risposte che possono richiedere settimane o mesi.
Appena rispondi, ti riagganciano subito, boh.
Con TrueCaller l'ho bloccato così non squilla più, ok!
Kurzer Klingelton, dann sofort Auflegen.
Messaggi indesiderati, suona per due secondi e poi riattacca.
Ich habe geantwortet, aber niemand reagierte und die Leitung wurde beendet.
Una chiamata è arrivata sabato sera alle 21:40 e di nuovo alle 21:50! Incredibile, ma non ho risposto.
Mi hanno telefonato sostenendo di condurre un sondaggio per le radio italiane sulla frequenza d’ascolto. Ho risposto subito che non mi interessa, che noia.
来电显示未知，通话内容不明确，建议保持警惕。
Un solo segnale
对方说话清晰，信息透明，给人可靠的感觉。

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.
