OSINT Resources for Phone Numbers

Phone numbers are essential in open-source intelligence (OSINT) for gathering details about individuals and organizations. This page highlights free tools for utilizing phone numbers in investigations. From identifying the origins of phone numbers to exploring associated social networks, these tools transform phone numbers into key investigative insights.

🗒️ As part of OSINT Tools Tuesday, this compilation also serves as a guide for tutorials available to paid subscribers. Each tool will eventually be linked to a tutorial explaining its use, application, and relevance, organized by Web Apps, GitHub projects, and Use Cases.

This page is a work in progress. In the future, I want to expand this beyond just tools and also into techniques.
