Case Study: Carousell achieves 67% reduction in fraudulent activity and faster, secure user communications with Vonage

Carousell Enhances Customer Engagement and Safeguards Against Fraud with Vonage

Carousell, a leading consumer-to-consumer marketplace in Southeast Asia and beyond, faced rising fraud from fake and multiple-account sign-ups that evaded email verification and threatened user trust and expansion plans. The company needed a reliable way to verify identities and improve timely communication between buyers and sellers while protecting brands and users.

Carousell integrated Vonage’s Verify and SMS APIs to implement phone-based two-factor authentication and real-time messaging for listings and inquiries. The solution boosted platform reliability and engagement, cut fraudulent activity by 67% by Q4 2020, and led to a drastic reduction in user support tickets.
