Use a reverse telephone directory to know the contact details of the cell phone or landline owner. Also use it to identify an unknown caller, to know if the call is a wrong number and to determine the precise location of the phone owner.
The reverse telephone directory provides the name and address of the phone owner. It is normally used by emergency services and the law enforcement agencies to know who called them requesting for assistance.
The directory is also used by individuals to know the name and address of the caller of an unrecognized number. Using the reverse telephone directory, individuals can also identify the geographical location corresponding to the phone number's area code. This helps to know where the unknown caller is calling from.
Additionally, such directories provide a map pinpointing the exact location of the caller. Through it, these directories enable people to get the directions to the place using the name and telephone number of the phone owner.
Once a number is identified as a sales or promotional call or as a wrong number using the reverse phone directory, individuals can determine if they need to call back.
Further, the reverse phone directory helps to determine if the calls to an unknown number, as indicated on the bill, were genuinely made by an individual. This way, the person can identify any errors in the phone bill and pay only for the calls he made.
