Check unknown Chinese numbers with recent reports (Beijing, Shanghai, Guangzhou, Shenzhen) and share your experience.
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.

Recibí un correo indicando que había sido aprobado para una Mastercard; al seguir el enlace observé que inicialmente dirigía a roofingmansfieldtx.com y luego redirigía a millstonemastercard.com. La búsqueda WHOIS del primer dominio mostró que estaba bajo Domains by Proxy, ocultando al propietario real. Al buscar el número, aparece asociado a una persona llamada Nina en Domains by Proxy, Arizona.
Use the official number from the website/app; avoid calling back the unknown number and check in‑app messages.
No. Portability/VoIP make 010/021/020/0755 and 13x/15x/18x ranges unreliable as proof.
Delivery updates, bank callbacks, 2FA codes; robocalls, parcel/account phishing and scripted sales.
