Is the student social security card useful after graduation

Whether it is still useful depends on local regulations. In some areas, because the system of employee social security card and student social security card is the same, students still use the social security card issued by the previous school even if they graduate, work and pay employee social security. In some areas, the original social security card will be automatically cancelled after graduation, and you need to take part in the work and pay employee social security before you apply for a new social security card.

Do college students need to cancel their social security cards after graduation?

Not necessarily. Since the social security card is now universal in the whole country, some areas can use the social security card issued by the school after graduation, and then go to the unit to participate in employee social security after graduation, and then continue to use the "card synchronization" business.

But it is worth noting that policies and regulations will be different. For example, social security cards issued by schools in some areas will be automatically cancelled after graduation. If so, college students need to apply for a new social security card after graduation. If you don't know the specific regulations, you can also consult the staff of the local social security department.
