My family's social security card is insured by my company. Can I use this card? Should I merge?

Hello, because I don't know what you belong to, I can't answer the question. The analysis is as follows:

1.

The company helps you pay social security: if so, your company helps you pay social security, and it doesn't matter if you apply for a social security card yourself, because your company has already paid it for you;

2.

You are paying social security yourself: if you pay social security card yourself, it is ok for your company to pay social security for you in the future;

3.

You are paying social security yourself: if you are still paying social security yourself, you may not be able to pay it in the same city if you apply for a card.

4.

I don't know what kind of situation you belong to. You can ask me when you adopt the answer, so that I can understand your situation and help you solve it.
