How to change the mobile phone number of social security card

The mobile phone number bound by social security card can be modified.

If the local social security card is linked to the bank and the social security card is authorized by the five major banks, then if it is necessary to modify the mobile phone number bound to the social security card, only the original social security card and the original ID card need to be provided, and the mobile phone can be directly changed to the corresponding bank.

If the local social security card is still set separately, I need to bring my social security card and mobile phone (which needs SMS verification) to the automatic service machine (or manual counter) in the social security service hall in the city to modify it myself.

There are different requirements for handling social security cards in different places. It is recommended to call the local social security card management department directly to change the mobile phone number.
