- Mobile phone numbers are often linked to billing addresses, frequently visited locations (through app usage data with consent), and even preferred store locations. This allows for targeting based on where customers live, work, or regularly visit, not just where they are at a given moment. Imagine targeting office workers near your cafe in Bandra during lunch breaks, even if they aren’t physically in your geo-fenced area at that exact second.

For example, a restaurant could target customers who live within a 5km radius and previously ordered Italian food with a special offer for their new pasta dish.
Implementing Location-Based Strategies with Phone Numbers
Leveraging phone number data for location-based advertising requires careful planning and adherence to privacy regulations.
