What is a Reverse Phone Lookup?

A reverse phone directory (also known as a greypages directory) is a set of telephone numbers and associated caller information. However, unlike a standard telephone lookup, where the user searches customer's details (such as name and address) to find the telephone number of that person or business, a reverse phone directory allows a preson to search with a phone number in order to locate the customer information.

Reverse phone directories can be used by law enforcement or other emergency services in order to find the place of a call for assistance.
