Hey mama! So the pincode they're asking for is basically your postal code, it's the 4-digit number na assigned sa iyong area para sa mail delivery, like how your barangay has its own code para sa addresses. Best way to find yours is to ask sa iyong barangay hall or check your recent bills (electricity, water), lagi nandoon yan, or you can search online using your barangay name! Let me know kung nahanap mo na, marami sa amin dito na VIP members kaya sigurado lang yan hehe.
