If you don’t have time to go to the nearest NSO office to get your birth certificate, you can do it online now.
All you have to do is to go to the E-census website and file your application there. You can pay online via credit card and your birth certificate will be delivered to your house. You can also pay over the counter on any Equitable PCI Bank and Unionbank branches nationwide.
Their service is not limited to birth certificate. You can also get your marriage certificate, certificate of no marriage (CENOMAR or singleness) and even death certificate.
I actually used their service last week and I’m still waiting for the documents to be delivered this week. It is already on the “Processed” status when I checked it today. Just go to their website for more information.
