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.
电话内容不太可信，但也没有特别让人反感。
Se trata de un número serio de Auto Hero.
Qualcuno mi ha detto che era la telekom e voleva vendermi un tariffa per la fibra ottica, ma non ci credo, e' troppo bello per essere vero
It's suposed to be TIM, they keep calling me at odd hours, so i just blocked the number
Sono gli soliti idioti, pero' non so cosa volessero, forse erano solo dei disturbatori, pero' non sono sicuro
Otrzymane nagrody są bardzo świeże i smaczne, naprawdę pyszne
电话那头的声音太搞笑了，好像是在现场制作奖品，讓我们吃到最新鲜的食物，真是太好了d
Che piacere! Ho ricevuto un premio con tanti prodotti deliziosi: curry, cioccolato, birra e tè. Non mi aspettavo una tale generosità, e tutto è così buono! Il tè, però, mi ha fatto venire sonno, ma non importa, continuerò a godermi i miei premi
这个奖品真的是太好了，讓我想起了我過世的家人，感覺很温暖，谢谢你们g

Use the official number from the website/app; avoid calling back the unknown number and check in‑app messages.

Delivery updates, bank callbacks, 2FA codes; robocalls, parcel/account phishing and scripted sales.
