I would like to ask if I can get two social security certificates in Beijing and Tianjin, and finally I can get more than two places.

At present, there is no national social security network, so it is possible for both cities to participate in the insurance. However, when you need to merge into one place (you need to accumulate social security payment years) or later, you will be told that if different regions pay social security at the same time, you need to voluntarily give up the social security payment years on one side and return the personal account amount to the individual.

On the whole, it is not recommended to insure in different places at the same time. If you are insured by stages, it is best to have a place where the payment period exceeds 10 years, and choose this area as the area for retirement procedures. (When reaching retirement age, the old-age insurance needs to be paid in 15 years, and many regions require that it be paid in the local area at least in 10 years before going through retirement procedures in the local area. )
