How to do reverse lookup in a Hash?

How do you conduct a reverse phone lookup?

• I tried a site called http://www.WhosePhoneIsThis.com to try and uncover the identity of an unknown phone call. However, the site wanted to charge me for a premium reverse phone lookup. Are there any free reverse phone lookup services out there?

• Answer:

  I am in charge of research and testing for an online consumer review site (www.CompleteReviews.net) and my assignment for the last 3 months has been public record search sites. Reverse Phone Lookup sites fell under that and I have to tell you, I found more garbage in this area than in any other public search category. There are so many sites that try to make you pay for a phone number you could just as easily find in the phone book. That is a scam! The only kind of reverse phone lookups for which you should pay are unlisted and cellular numbers because the lookup site has to pay for access to this information. The problem for you at this point is that, since you are dealing with an unknown caller, you have no idea if that number is unlisted or not. The scam sites will charge you either way so you need a site you can trust. I can only vouche for the sites that passed our testing requirements. You can find the top 3 at http://www.completereviews.net/reversephonelookup.html . They have access to billions of records and provide guarantees to their customers. Good luck in your search.
