Thousands of men and women reverse search cell phone numbers everyday in the USA.
Among the commonest reasons for people to trace cell phone numbers are:

• To nail a cheating girl/boy friend
• To nail a prank caller
• To check on who their teenage children are talking to

Whatever your reason may be, there are several options you can try

1. White Pages
2. Private Investigators
3. Online reverse phone search databases

White pages - Neither the white pages nor any other publicly available phone book have access to cell numbers.
This is not a deficiency of the system.
Instead it has been done deliberately to protect mobile phone users' privacy rights.
There are even actual privacy laws that safeguard wireless phone subscribers.
So the short answer is, no white pages can not help you with any of the unlisted numbers.
Private detectives - Not only were they great, but they were also our only option a decade ago.
They were 'pricey' yet slow.
Nowadays they have got cheaper and faster, because they also use the same databases that you and I have access to.
So why go through a detective when we can access these online databases ourselves? Online databases - undoubtedly the best option because:

• In today's world, time is of essence.
  Good databases give you results in as little as 2-3 minutes.
  
• You get access to quite a lot of information on the phone owner such as - his/her Full name, Age, Exact Address, Relatives, Associates, Average Home Value and Income etc.
  
• It's 100% confidential - you can do it from the comfort of your home/office computer whenever you please
• You're not limited to searching a single number.
  You can reverse lookup as many wireless/land/unlisted numbers as you wish
