Why does a social security have two numbers?

A citizen has two social security numbers, which may be because the multiple payments are not from the same company and there is no transfer. The social security account number is identified by the ID card. If the ID card is not duplicated, the social security account number cannot be duplicated.

Citizens with two social insurance numbers can be dealt with in the following ways:

1. If the ID number and name of the reserved number are correct and the merged number is suspended, and the ID number or name is wrong, the social security agency will merge the individual social security number, and then the local tax department will directly cancel the merged number;

2. If the ID number or name of the reserved number is wrong, and the combined number is suspended and corrected, the social security agency will issue a business cooperation letter asking the local tax department to modify the personal basic information first, and then return to the social security agency to operate according to the original business process of the combined personal social security number.

3. The insured person not only has the payment history of urban workers, but also has the insurance experience of urban and rural residents, farmers who moved into rural areas and landless farmers, and has multiple personal social security numbers because of their different identities, and will apply for it when they reach the legal retirement age.

The role of social security card:

1, social security card records personal social security related information, electronic certificate and information inquiry, etc.

2. Record the insured's name, ID number, date of birth, gender, nationality, household registration and other basic information.

3. You can check my pension, unemployment, medical care, work injury and maternity insurance payment.

4. You can take the card to the hospital and go to the pharmacy to buy medicine.

5, can handle medical care, unemployment, pension, work injury and maternity and other social security affairs.
