Kakao Corp is using Vonage’s Number Insight Advanced API to authenticate new users of KakaoTalk, South Korea’s leading instant messaging mobile application, before sending them a verification PIN code via SMS to enable registration. The Vonage API identifies phone numbers around the world, assesses risk, prevents fraud and blocks fake accounts — all without relying on customer input. Using real-time phone number intelligence, Vonage’s API determines if a phone number is valid, reachable, a virtual number or landline, triggers step-up authentication when needed, and prevents costly fraudulent transactions.
Kakao Corp quickly and easily implemented Vonage’s Number Insight Advanced API within its existing platform without changing current processes and uses the solution synchronously to minimise time spent validating numbers.
“The mobile industry is rapidly evolving and service providers face a rising flow of spam and fraudulent traffic that is increasingly difficult to detect and control. It has become critical for service providers to ensure customers of a secure platform, build trust, maintain their reputation and do so without incurring extravagant costs. The Vonage Number Insight Advanced API helps businesses verify their users easily, enabling them to create a safe environment for existing customers while attracting new ones,” said Sunny Rao, Vonage Senior Vice President, API Global Sales.

Markets in the region are responsible for approximately 60 percent of financial exposure worldwide.1 This has pushed businesses to invest more in security solutions to safeguard their applications.
