Hi mama! Yung pincode sa VIP sign-up ay yan talaga yung zip code ng address mo, so kung bakit ayaw mag-sign ng account mo, baka may spacing issue or special characters na hindi dapat there, try mo lang i-input as numbers lang without spaces or dashes. One of my mum friends had the same problema and nag-contact siya sa theAsianparent support, sobrang helpful daw sila sa ganitong technical stuff, so if it keeps giving you trouble, that's your best bet!
