# Phone Number OSINT

Phone number OSINT focuses on investigating telephone numbers to uncover associated identities, accounts, and activity across publicly available sources. These techniques help analysts determine who may be linked to a number, where it has been used online, and whether it is connected to spam, fraud, or legitimate services.
