Why can't social security be paid in? What is the reason?

This situation may be that the social security card has not been activated and the social security password has not been modified.

1. The social security card is not activated: the social security card has two passwords, one is the bank card password and the other is the social security password. You need to activate the social security card at the bank to modify the initial social security password.

2. The social security card has not changed the social security password: the social security card is a card with two passwords, which has the functions of both social security card and bank card. It is not enough to activate the social security card only in the bank. You need to hold a social security card and valid identity documents to set up a social security password at the county (district) level social security bureau or a designated pharmacy.
