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.

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.
