Article 58 An employing unit shall, within 30 days from the date of employment, apply to the social insurance agency for social insurance registration for its employees. 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.

Article 63 If an employer fails to pay social insurance premiums in full and on time, the social insurance premium collection agency shall order it to pay or make up within a time limit.

If the employer fails to pay or make up the social insurance premium within the time limit, the social insurance premium collection agency may inquire about its deposit account in banks and other financial institutions, and may apply to the relevant administrative department at or above the county level for making a decision on the allocation of social insurance premiums, and notify its bank or other financial institutions in writing to allocate social insurance premiums. If the balance of the employer's account is less than the social insurance premium that should be paid, the social insurance premium collection agency may require the employer to provide guarantee and sign a deferred payment agreement.

If the employer fails to pay the social insurance premium in full and fails to provide guarantee, the social insurance premium collection agency may apply to the people's court for sealing up, distraining and auctioning the property whose value is equivalent to the social insurance premium that should be paid, so as to offset the social insurance premium with the proceeds from the auction.
