SSS branch in Pasay is very accessible. This past week, I was able to visit the branch, it is basically just in front of the building where the NSO Pasay branch resides and is just next to PNB building. Going to the branch would allow a member to request for the processing of SSS ID, pay their respective monthly contribution, and update status of their membership. Aside from that a member can also request for medical and other related claims. SSS membership can also be done for non members.
Here are simple instructions on how a member can visit SSS branch in Pasay:
The fastest way is to ride LRT 1 then get off at Gil Puyat station. In front of Jac Liner bus terminal, ride a multi cab passenger jeep then tell the driver to drop you off at SSS.
If you have planned to visit SSS Pasay, based on my experience it would be better to go to the place before at 8AM or early as 9AM and in the afternoon at around 2PM. Things to bring are 2 valid IDs, ballpoint pen, light snacks and drinking water.
