Many on-line telephone directories are available but their accuracy and accessibility vary. One of the primary on-line telephone directories is www.anywho.com This directory allows you to search for a person or business directly or reverse for phone number. The results are not consistent for an individual and people are associated with phone numbers and addresses that have no relationship to the address.
Using myself and my address, the database listed names that should and should not have been associated with the address and phone number. It offered no current phone number for me. When I put in my phone number into a reverse directory, it pulled up the names Troy Boyle (unknown person to me) and Archer Boyle who was the original number owner and who has been dead for 13 years.
