Regardless of what you read online… as of this writing (please check the date of my post!), there is only one EASY way of knowing what your PhilHealth ID Number is without access to your PhilHealth ID (if you have lost it or left it at home and need your number for any reason at all):
From the province: (02)-441-7442
This is PhilHealth’s Official Call Center.
Now, be ready to wait. The last time I called, I waited for 5-7 minutes for a representative to answer the phone because they were queuing and literally being flooded with calls! However, the wait will definitely be worth it, as you just need to give your name and birthday and you will get what you called in for, plus any other PhilHealth-related information you might happen to want to know the answer for.
