Is it illegal to pay two social insurances in different places?

Legal analysis: it is not illegal to pay two social security in different places. But it is impossible to receive two pensions in the future. For everyone, social security is the only identification object with ID card. When you retire, you can only choose one place to retire. For the social security part paid repeatedly, the social security fee paid in one place will be refunded after retirement in another place. There is no situation that two places buy social security and two places receive two pensions after retirement.

Legal basis: Article 58 of People's Republic of China (PRC) Social Insurance Law. The employing unit shall handle social insurance registration for employees within 30 days from the date of employment. If the social insurance has not been registered, the social insurance agency shall verify the social insurance premium it should pay.

Employees-free individual industrial and commercial households who voluntarily participate in social insurance, part-time employees who do not participate in social insurance in the employing unit and other flexible employees shall apply to the social insurance agency for social insurance registration.

The state establishes a national unified personal social security number. Personal social security number is a citizen's identity number.
