Is it normal for mobile customer service to require verification code?

1, confirm the identity

Confirm whether the customer service identity you are talking to is true. Regular mobile customer service will contact you through official channels, and will not obtain your personal information or ask you to provide sensitive information through unofficial channels.

Step 2 confirm the purpose

Need to confirm the purpose of customer service. If this is the purpose of customer service, it is reasonable to provide the verification code.

Step 3 protect personal information

Don't easily provide personal sensitive information, such as ID number and bank card number. If customer service must ask you to provide this information, you need to be very careful.
