As you know, to be able to apply for a new passport you need to have at least one valid ID.
Good news to all applicants, another ID has been added to the list of acceptable valid ID’s for passport applications.

Starting 1 August 2019, the Department of Foreign Affairs (DFA) will start accepting the Philippine Postal Corporation (PhlPost) ID as a valid government-issued ID for passport applications.
This comes after the DFA and the PhlPost signed a Memorandum of Agreement (MOA) on the acceptance of PhlPost IDs as a valid ID for passport application on 08 July 2019.
The MOA also provides the establishment of the Postal ID Online Verification System (POVS), a software application that facilitates the easy verification of the PhlPost ID.
