Individual industrial and commercial households can pay social security for several people.

Legal analysis: the law does not clearly stipulate the limited number of self-employed people to purchase social security. In principle, enterprises or self-employed individuals are obliged to pay social security for all employees. The specific procedures are as follows: within 30 days from the date of obtaining the business license (or being approved to be established), go to the local tax collection hall to register the unit payment and individual payment with the following documents and materials: (1) documents approved by relevant departments (photocopies); (2) Business license (copy); (3) Organization Code Certificate issued by Technical Supervision Bureau (copy); (4) Identity card (photocopy), transfer order, preparation card, letter of introduction of cadres and workers (photocopy) or labor contract of the insured.

Legal basis: Article 4 of People's Republic of China (PRC) Social Insurance Law. Employers and individuals in People's Republic of China (PRC) pay social insurance premiums according to law, and have the right to inquire about payment records and personal rights records, and require social insurance agencies to provide social insurance consultation and other related services. Individuals enjoy social insurance benefits according to law and have the right to supervise the payment of their own units.
