Can I apply for social security in two companies at the same time?

Legal analysis: social security can only be paid after registering identity information. Generally, the same person can't pay social security twice in the same overall planning area, and the payment period can't be superimposed in two units, so repeated payment is useless. Generally, only one unit can pay social security in the same overall planning area. Social security is an insurance system that the state forces employees of enterprises or units to pay to prevent accidents after retirement, which is essentially insurance.

Legal basis: Article 38 of People's Republic of China (PRC) Labor Contract Law. Under any of the following circumstances, the laborer may terminate the labor contract: (1) failing to provide labor protection or working conditions as agreed in the labor contract; (2) Failing to pay labor remuneration in full and on time; (3) Failing to pay social insurance premiums for laborers according to law; (4) The rules and regulations of the employing unit violate the provisions of laws and regulations and damage the rights and interests of workers; (5) The labor contract is invalid due to the circumstances specified in the first paragraph of Article 26 of this Law; (6) Other circumstances under which the laborer can terminate the labor contract as stipulated by laws and administrative regulations. If the employer forces the laborer to work by means of violence, threat or illegal restriction of personal freedom, or if the employer illegally directs or forces the risky operation to endanger the personal safety of the laborer, the laborer may immediately terminate the labor contract without notifying the employer in advance.
