Can Unicom customer service ask for verification code?

I can't. According to Zhaofa's inquiry. Com, Unicom customer service needs to verify the mobile phone number and pass the company's internal system verification. Unable to verify whether the caller is a customer service person. In order to reduce unnecessary losses, don't tell others the verification code casually, and don't provide the verification code of your mobile phone to anyone.
