As you may know, cell phones have a caller ID which tells you directly who is calling you and the respective number.
If your home phone has a caller ID too, you can easily see the incoming call info.
Before this, you couldn't see the caller name on your phone and even before that you couldn't even see the calling number.
When this feature was available on our phones, it allowed us to identify who is calling before picking up the phone and to know which numbers belong to our family and friends.
After this it was introduced the reverse phone lookup and this makes possible to regular users to discover the caller details like its real name and address.
The reverse phone lookup directory has several uses.
If someone is calling you frequently and you just have the missed calls from an unknown number you may want to know if this is a serious caller or if there is an emergency or if someone has nothing to do and is just messing with you.
Of course, the only way to know this is by using a reverse phone lookup search service.
You may also want to reverse search a number to find out who owns a certain number you may have on your phone book with no name.
You may also want to identify someone who may be harassing you or someone you don't want to talk to, so it's better to reverse search that phone number and verify who it belongs to.
Of course, if you are on a relationship and you think your partner may be cheating on you, you can always get the number which your partner receives their calls or makes calls to and make a reverse phone lookup search on it.
This way you can always track the story down and discover if you are really being cheated or not.
