Tracking phone calls in GA4, as of early 2026, relies on attributing conversions to marketing efforts by linking phone calls initiated from your website or ads to specific GA4 events and user journeys.

• GA4 Enhanced Conversions: Current systems include the ability to upload offline conversion data – meaning calls received – directly into GA4, linking them to Google Ads campaigns.
• Call Tracking Integrations: GA4 now features native integrations with leading Australian call tracking providers like CallRail and Telstra’s Smart Messaging platform. These integrations automatically send call data (duration, source, outcome) to GA4.
• Event-Based Tracking: You can set up custom events in GA4 triggered by clicks on phone numbers on your website. These events can then be linked to call tracking data for a complete picture.
• Consent Mode Integration: Crucially, in 2026, respecting user privacy is paramount. GA4’s Consent Mode integration ensures call tracking data is handled compliantly with Australian privacy regulations.

This is particularly important for Australian businesses, where a significant portion of leads still initiate contact via phone. Accurately tracking these calls allows you to optimise your marketing spend, understand which channels drive the most valuable phone inquiries, and personalise the customer experience based on call data.
