Our subscriptions grant a certain number of credits to unlock the contact info of a person.  However, to use a credit you have to do a few things.

First, you have to either click Show Contact Info for a profile, export a profile or list of profiles, or send an email (basically 3 ways to engage a person).  Then, if WhoKnows has a verified email or phone number, we'll charge you a credit for that profile.  

Lastly, that profile is unlocked forever and you can access their contact info as long as you want.
