What about the social security cards of the two places?

Legal analysis: two social security cards in different regions can be merged under certain conditions, otherwise only one social security card can be cancelled. The conditions that can be merged are that they have participated in comprehensive insurance or basic endowment insurance for urban workers, and there is no transfer between comprehensive insurance and basic endowment insurance for urban workers. Under this "premise", they can merge with the comprehensive insurance or the basic old-age insurance for urban workers from 2009 10, if they transfer their land to social security. According to the regulations on the management of social security cards, each resident can only apply for one social security card. I have received my social security card. When the cardholder (or legal representative, guardian, spouse, children and other relatives) applies for cancellation of the social security card, he should first apply for cancellation of the social security card to the social security card handling service agency of the social security department in the place where the card is issued or the social security card is transferred out, and then cancel the bank account at the social security card service bank outlet. So you can cancel it at the card office, or you can go to the local area before cancellation.
