If you're being bothered by unlisted callers you need reverse number look-up.
One simple Internet download can provide you with unlimited phone number traces - including unlisted numbers.
Before reverse number lookup services became easily available via the Internet, discovering the source of unfamiliar calls that showed up on your call display - or on your monthly phone bill - often proved difficult or impossible.
If you're like me and an out-of-area number shows up early in the evening, just when you're about to eat, it just screams "marketing call".
Rather than give yourself indigestion, you ignore it.
Often these callers won't leave a message on your answering service.
I think it's important to find out exactly who is calling.
If it is a marketing or opinion survey you can contact them and demand to be removed from their calling list.
But the ignored caller could also turn about to be a pest of a different kind...
like the taxman, for instance! You'd sure like to know he's after you - and for how much!.
And what if that call is a family member or friend out of town who urgently needs help? If you had a reverse number look-up service that told you a hospital in a distant city had called, you'd know this really needed to be followed up.
And let's not forget the possibility of harassment - repeated calls from someone who simply hangs up every time you answer.
A reverse number look-up will provide you with the name and address of the caller.
You might recognize the name of a disgruntled ex or a former employee - information the police must have to put a stop to the problem.
As well as finding out the name and address of the person or business that's been calling, you can also trace cellphones, pagers and fax numbers - even a public payphone.
And no one will ever know you secretly "looked them up" as all searches are 100% confidential.
