Development Story
Every day, millions of Vietnamese face sophisticated scam calls impersonating banks, police officers, or even distressed family members. Many families have lost their life savings to a single unexpected phone call.
Trang Trắng was born from a simple idea: if each user shares information about a suspicious number, the entire community becomes protected. We built a platform where people connect and warn each other about potential dangers hidden behind unknown calls.
Today, every report you make not only protects yourself but also helps millions of others avoid unfortunate risks. Trang Trắng brings people together to build a safer community for everyone.
