Truecaller South Africa

In a digital advertising landscape full of clutter and ad fatigue, finding a channel that captures genuine, undistracted user attention is increasingly difficult. Until now, there has been a near-complete content void on how to leverage one of the most powerful mobile platforms available in the South African market: Truecaller.

As the exclusive reseller for Truecaller Ads inventory in South Africa and Kenya, 365 Digital is here to provide the definitive guide. Truecaller is an essential communication platform for over 450 million active users globally. By combining Truecaller’s platform intelligence with our deep local market expertise, we unlock new value and data-driven advertising solutions at scale for South African brands.

The ROI of Verified Attention

Why does Truecaller work so effectively? It all comes down to trust and verified attention.

100% Screen Attention: When a phone rings, users pay 100% attention to the screen to see who is calling. Your ad is unmissable because users must look at the screen to interact with their calls.
Zero Competition: Your brand owns the entire screen. There is no clutter and no distractions, just your message.
Brand Credibility Transfer: When brands appear in Truecaller’s verified environment, they gain credibility by association.
Identity-First Moments: Every interaction begins with a cognitive pause where users ask, "Who is this?". This creates behaviour rooted in trust and awareness, meaning exposure is shaped by intent rather than accidental clicks.

Precision Targeting for the South African Market

Truecaller moves beyond traditional cookie-based tracking by leveraging unique offline and online signals to reach your exact customer.

In South Africa specifically, brands can target massive vertical-specific segments:

Entertainment: 4M+ Users
Social & Communication: 3M+ Users
Finance & Insurance: 2M+ Users
Home & Lifestyle: 2M+ Users
Automotive: 1M+ Users

How we target:
