How do you find out a person's cellphone number?

To find out someone's cell phone number, a person can use Yellowbook or National Cellular Directory. To use the former, all one has to do is enter the first name, last name and state location of the person into the relevant search boxes.

Then the "Search" icon should be clicked on. For those who are unsure of state location, they can select "Nationwide" to do the search. To find out using National Cellular Directory, all one has to do is enter the person's first name, last name and city and state location into the relevant search boxes before clicking on the "Search" icon. The National Cellular Directory offers one "Happy Hour" during which time anyone can use the premium directory for free.
