Do I have to go to the bank to bind my social security card to my mobile phone number?

Social security card must go to the bank to bind the mobile phone number.

1. Reservations can only be made in the bank lobby, and individuals cannot modify them online.

Because you need to fill out a paper application form.

3. To modify the reserved mobile phone number, you can go to any branch of the corresponding bank and go to the counter. I can go to the bank counter with my ID card and bank card, or I can go to the bank with my personal ID card and bank card to fill out the application form for information change. After going through the binding formalities. Add the bank card to wechat. The social security card can be used normally on WeChat. Add the bound social security card to Alipay. Social security cards can also be used normally on Alipay. In other words, the social security card bound by the bank can conduct financial activities online.

It doesn't really make sense for banks to reserve mobile phone numbers. The mobile phone number reserved by the bank is just a way for the bank to contact you.
