After users complete a call, Truecaller displays an After Call Screen (ACS) summarizing the call duration and other details. This is a moment when the user is still actively engaged with the phone, making it a high-value ad slot. Display ACS places a banner ad on this screen, ensuring your brand is seen at just the right time. These ads are ideal for promoting offers, app downloads, or increasing brand awareness with measurable impressions.

Video ACS takes engagement to the next level by delivering rich media content post-call. These full-screen video ads play automatically after a call ends, offering a premium viewing experience. Brands can use this format to tell a deeper story, launch a campaign, or showcase a product in action. With the user’s full attention on the screen, Video ACS delivers higher retention and brand recall rates compared to traditional video ad placements.

Display In-App ads are standard banner or medium rectangle ads placed within the app’s UI. These can appear while users are browsing contacts, searching for numbers, or interacting with app features. This always-on format ensures constant visibility and brand presence, ideal for campaigns focused on sustained awareness. The ads can be targeted by demographics, location, and user behavior, ensuring relevant impressions.

This is one of the most performance-driven ad formats Truecaller offers. Click-to-action ads feature buttons that let users instantly contact a business via WhatsApp, SMS, or a phone call. Whether it’s for lead generation, customer support, or direct purchase inquiries, this format creates a seamless bridge between the user and the brand. These ads are perfect for driving immediate engagement and conversions, making them highly effective for service-based businesses and e-commerce.

Carousel ads allow multiple creatives to be displayed within one ad unit. Users can swipe horizontally to view a series of images or promotions. This format is especially effective for brands that want to showcase a range of products, features, or offers in a single frame. It supports storytelling and sequential messaging, making it suitable for campaigns that aim to educate, demonstrate, or entice with variety.

Brand Sponsored Icons appear during the call interface, where the caller ID and other on-screen details are shown. These icons can be customized with the brand’s logo or identity, subtly integrating the brand into a core utility experience. This high-frequency, low-intrusion format ensures continuous exposure every time a call is made or received, reinforcing brand familiarity without disrupting the user’s activity.

Sponsored Bubbles are floating branded icons that appear on the screen while the user navigates the app or their device. Similar to chat heads in messaging apps, these bubbles stay visible and can be interacted with. Clicking on the bubble can expand to show a message, offer, or redirect to a landing page. It’s a creative and persistent format that keeps the brand top-of-mind during extended user sessions.

Interstitials are full-screen ads shown at natural transition points within the app, such as when opening the app or switching tabs. These high-impact visuals are impossible to miss and are excellent for bold campaigns, app installs, or brand takeovers. Since these ads take over the full screen, they are ideal for messages that need maximum attention and visual real estate.

Caller ID ads are one of the most integrated and seamless ad formats in Truecaller. These appear during an incoming or outgoing call, displaying a small, branded banner or message alongside the caller ID information. Since users rely heavily on caller ID, this format ensures strong visibility without being intrusive. It blends into the user’s natural experience while reinforcing brand presence at a key utility moment.
