Foreign household registration pays social security.

Legal analysis: social security payment means that social security payment is interrupted for some reason and has not been paid for several months. Now, due to recruitment or other reasons, it is necessary to make up the part that has not been paid before, in order to obtain a complete social security period and ensure the normal identification of recruitment and settlement. Under normal circumstances, the general unit can only make up for 2 months. If it takes longer, it has to be operated through some agencies.

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.
