Individuals need to pay social security in both Beijing and Tianjin.

No, although there is no internet connection now, you have achieved the goal of payment between the two places, but you will eventually merge together. If you find such a situation, you can only return the duplicate part paid by the individual to yourself, and the part paid by the unit will not be returned. Speaking of it, it is a loss to individuals and payment units.

Therefore, it is absolutely impossible.

If it is necessary, such as issuing an insurance certificate, it should be easy. Just swipe your ID card on the self-service printer of the social security center at the place of payment.
