Can the social security paid by Yiwu, a foreign household registration, be used at home?

Of course. However, social security transfer is required. Once transferred to the local area, you can't use it when you return to your hometown.

In order to ensure that the insured can't use the social security card normally due to the change of work or study place, the insured can handle the social security card transfer business at the Social Security Bureau with his ID card and social security card.

If the insured person has a social security payment record outside the scope of overall planning, it is necessary to issue a certificate of insurance payment to the social security agency of the original insured place, and then go through the social insurance transfer formalities at the social security bureau, so that the social security paid by the original insured place can be transferred to the social security account of the current insured place.
