There is no instant lookup or database with the customer information for all toll free numbers.  You can try Google.com, Anywho.com and GoTollFree.com.  The end user information is one of the most valuable things you can get when you're pursuing a good number, but unfortunately there is no good nationwide pool or database to get this important information.  It's often very hard to get the end user after a toll free number has been disconnected. 

One of the most valuable tools I've developed that is the key to securing great numbers for my consulting clients, is one of the very best professional investigators in the country for tracking down end user information.  I not only use but make this professional service available because it's often the best way to come up with a really good toll free number.  I recommend and use this for really good numbers that don't go to any active customer but show up as active in the national database.  There's often a good chance you'll be able to get this number if you could just reach the owner.  It costs $195 and takes a couple days since it's not an automated lookup but this is one of the most valuable tools in tracking down a really good number.

I usually recommend that clients contact the phone company for a number first because if you can get the end user information from the phone company you wouldn't want to pay for it.  (See phone company lookup)  Having this information can also help you in pursuing the number through the phone company too.  There is also more information on how to locate and then approach the end user in "The Process" or my ebook "Phone Numbers That Make Money."

There's no way to guarantee or really even predict whether the owner will be willing to give you the number or even be alive or locatable any more.  But I can guarantee you that we'll get you the end user information or you'll get your money back.  And even if we get you the customer name and address, if you still can't get the number, we'll also deduct the CNA fee from our consulting fee if you want us to pursue this number for you.  That way you can't lose, except by not trying!
