Is it still viable to get a Postal ID?

This is coming from someone who has a PhilID, NPDL, and Passport. Siyempre ekis talaga sa pag bitbit ng passport everywhere. Di naman rin pwede iwanan yung NPDL sa gate ng subdivisions or schools kasi that already a failure to carry violation. Praning naman ako mawala yung PhilID lalo na ang tagal bago makakuha ng plastic card haha.

Was looking to get a Postal ID as my pang-iwan na ID. Is this advisable?
