Legal analysis: college students can pay social security. Anyone who has reached the age of 16 can participate in social insurance, but college students are not employees of enterprises, and enterprises do not have labor customs departments, so they cannot participate in endowment insurance for urban employees. College students can only participate in flexible employment or residents' pension insurance. If you want to participate in the endowment insurance for urban workers, you must sign a labor contract with your unit after graduation, and you can only participate if you have labor relations.

Legal basis: Article 10 of People's Republic of China (PRC) Social Insurance Law * * * Employees shall participate in the basic old-age insurance, and the employer and employees shall jointly pay the basic old-age insurance premium. Individual industrial and commercial households, part-time employees and other flexible employees in useless units who have not participated in the basic old-age insurance can participate in the basic old-age insurance and pay the basic old-age insurance premium.
