South Korea-based mobile services provider Kakao has chosen Vonage to safeguard its platform against fraud and enhance the speed and efficiency of customer notifications.

Kakao is using Vonage’s Number Insight Advanced API to authenticate new users of the KakaoTalk 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.

“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,” said Sunny Rao, Vonage Senior Vice President, API Global Sales.

“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,” said Rao. “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.”

KakaoTalk averaged more than 52 million monthly active users in August 2020 in South Korea. It is available in 15 different languages with more than 150 million users worldwide. Messages sent on KakaoTalk reach a daily average of 11 billion.

With an ever-growing network of more than one million registered developers, the Vonage Communications Platform promises to make it easy for businesses to use APIs to disrupt their industries, and enable the type of business continuity, remote work, and remote delivery of services that is so essential in today’s environment. 

Vonage APIs allow developers to easily enhance and build innovative customer experiences directly into their existing applications and devices. The Vonage Communications Platform offers a full suite of programmable voice, video, messaging, and email services to forward-thinking businesses worldwide.
