Before that, I worked in the counter position of a securities company for two years, and the position was counter handling. To put it bluntly, it is to open an account for investors! Opening a securities account requires me to go to the counter with a valid second-generation ID card, or you can follow the online account opening process! Here I only talk about the situation handled by the counter. When handling the counter, it is necessary to verify whether the account holder's mobile phone number is true, which is for the sake of compliance and to better serve the needs of investors in the future! Of course, your mobile phone number can be used as an emergency contact, that is, when you can't contact the investor who opened the account, you can contact the account holder.
