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.
