Will the social security transfer voucher be invalid?

1. The social security individual account and the overall account themselves will not expire: however, the transfer procedures of the parties have a certain period (please consult the staff of the social security department at the transfer place for details); 2. During this period, the transfer formalities have not been handled (or during the period when the transfer has not been handled, the party concerned is no longer employed in the new unit, etc.). )
