Corps 12333 Social Security Inquiry Network

Corps social security and municipal social security are still two independent systems, and there is no networking. Afraid of missing the Corps' good social security policy, you can continue to pay fees on both sides, and if you connect to the grid in the future (I don't know how many years later), you can pay fees while selectively returning. You can also stop paying one party's fees now and leave other things alone. When you retire in the future, the social security bureau will solve it for you. Anyway, it is very unlikely that both parties will get a pension.
