What should I do if I lose my social security book?

Legal analysis: 1. If the social security book is lost, the worker can report the loss at the nearest social security agency or replace it with his ID card (or household registration book);

2. If you want to change to a social security card, you need to provide a one-inch color photo (subject to the photo of the second-generation ID card);

3. If you entrust others to handle it, you should bring the ID card (or household registration book) of the principal and agent.

Legal basis: Article 74 of the Social Insurance Law of People's Republic of China (PRC), social insurance agencies obtain information needed for social insurance work through business handling, statistics and investigation, and relevant units and individuals shall provide it in a timely and truthful manner. The social insurance agency shall establish a file for the employer in a timely manner, completely and accurately record the social insurance data such as personnel's participation in social insurance and payment, and properly keep the original vouchers for registration and declaration and accounting vouchers for payment and settlement. The social insurance agency shall timely, completely and accurately record the individual's personal rights and interests such as social insurance payment, employer's payment and social insurance benefits, and regularly send the personal rights and interests records to me free of charge. Employers and individuals can inquire and check the records of payment and social insurance benefits from social insurance agencies free of charge, and ask social insurance agencies to provide social insurance consultation and other related services.
