How can I verify the information for you for no reason? You have to ask what happened when they called you first. Is it a business recommendation? Or a preferential notice? Or research? Or pay a return visit? Or something else?
It is too simple to know your name, ID number, address, work unit, family situation and other personal information, because there are personal information materials for sale online. This year's CCTV 3 15 party exposed that China Telecom helped others send spam messages, and also exposed that China Merchants Bank and Industrial and Commercial Bank Credit Card Center openly sold important personal information of customers.
In China, personal privacy is easily breached, and the laws are not perfect, so it is difficult to effectively protect personal information security.
