A phone number on Caller ID - wondered whose number it is, reverse phone lookup is for you. You can find out the person's name, address by using free reverse phone lookup or reverse
phone directories available on the Web.
A reverse telephone directory (also known as a greypages directory, criss cross directory or reverse phone lookup) is a collection of telephone numbers and associated customer details. However, unlike a standard telephone directory, where the user uses customer's details (such as name and address) in order to retrieve the telephone number of that person or business, a reverse telephone directory allows users to search by a telephone service number in order to retrieve the customer details for that service.
Reverse telephone directories are used by law enforcement and other emergency services in order to determine the origin of any request for assistance, however these systems include both publicly accessible (listed) and private (unlisted) services. As such, these directories are restricted to internal use only.
Publicly accessible reverse telephone directories may be provided as part of the standard directory services from the telecommunications carrier in some countries. In other countries these
directories are often created by phone phreakers by collecting the information available via the publicly accessible directories and then providing a search function which allows users to search by
the telephone service details.
