Do I have to go to the original unit to issue a certificate to transfer social security?

Social security transfer must be certified by the original unit.

Because the social security payment certificate is an important material to prove the social security payment of the original unit. If there is no social security payment certificate, it is impossible to prove the social security payment in the original unit, and it is impossible to transfer social security smoothly.

However, if you have left the original unit, or the original unit has been dissolved or bankrupt, you can't go to the original unit to open a certificate. You can apply to the local social security bureau for a social security payment certificate, which is issued according to personal information and social security payment records.
