How to change the social security card ID number?

Hello! It is divided into the following situations: (1) automatic upgrade. At present, the citizen ID number displayed on the social security card is 18 digits. If the ID number of the insured is 15 digits, the insured will exclude the seventh, eighth and last digit of this 18 digit when checking these two digits. No need to check, other digits are consistent and the name is correct. The insured person does not need to go through the change formalities at the social security agency. (II) In addition to the above, if the name on the card and the number of the citizen's ID card are inconsistent with my ID card, the person in charge of the unit shall fill in the Application Form for Change of Insurance Information, and attach the social security card, the original insurance information (enrollment form), the unit certificate and a copy of the ID card to the social security agency for data change procedures. (3) I apply for a new identity card or change my identity card, etc. If my name or ID number is changed due to the expiration of my ID card or other reasons, the insured shall issue a certificate of change to the local public security bureau, and the unit administrator shall fill out the Application Form for Information Change of the Insured, and go through the formalities for data change with the original certificate, the original ID card and its copy, and the social security card.
