What are the two social security numbers?

There are two social security numbers that may be due to the following reasons:

1. Social security is handled incorrectly, or different units have registered for social security.

2. The insured person has both the payment history of urban workers and the insurance experience of urban and rural residents, farmers who have moved in and landless farmers. There are multiple personal social security numbers because of different identities.

Use of social security number:

1, social security number is the information that everyone must provide when participating in social security, and it is the only sign that citizens participate in social security and enjoy social security benefits. Through the social security number, you can easily handle all kinds of social security-related matters, such as inquiring about social security payment details, enjoying social security benefits, handling social security cards, applying for social security subsidies, and so on.

2. The social security number can be used as an important symbol of citizens' personal identity, and can be used as a voucher for employment, enrollment, medical treatment, etc. It is an important symbol of a citizen's social security rights and interests, ensuring that citizens can enjoy the social security benefits they deserve.

3. The social security number also helps to realize the connection of social security rights and interests. When a person participates in social security in different regions or units, the previous social security rights and interests can be associated with the new insurance record through the social security number to ensure the continuity and integrity of social security rights and interests.

To sum up, social security number plays an important role in the field of social security. It is not only necessary information to participate in social security, but also an important certificate to enjoy social security benefits and handle related affairs. It is also a sign of personal identity and social security rights.
