Call ID app Truecaller has announced plans to actively engage Africa's tech innovation space.

At a launch event held recently in Lagos, Priyam Bose, the company's Director and Head of Worldwide Developer Relations announced plans to establish headquarters in Africa and said the company will soon be recruiting.

The business also launched its SDK developer programme through which it is offering its mobile identity product to African startups and developers to quickly verify end users.

The Truecaller SDK for third party app developers, digital businesses and startups is available for Android, iOS, and web platforms. It can be used by any app or a website to instantly onboard, auto-fill user information, and verify user phone number-based identity through the users' Truecaller profile.

The company says it has over 50 million users and blocks over 500 million spam calls monthly.

More than half of all the messages the app has filtered in Africa are spam, it adds.

Bose also described Nigeria as one of the most promising ecosystems in Africa. "After engaging with some of the top tech startups and digital businesses in the country, we are even more convinced that Truecaller SDK mobile identity solution will help solve many of their challenges when on-boarding and verifying new users," Bose said.

In Nigeria, Truecaller said it has over 6.2 million users in Nigeria and claims its user base grew by over 80% in the past year.

"Truecaller is helping Nigerian users to block more than 13 million calls, and 25 million spam SMS every month."

The business added that Egypt, Kenya, Nigeria and South Africa rank high among the top 20 countries in the world plagued by unwanted spam calls.
