Hey lordbyroniv.
someone mentioned above that
www.tollfreenumbers.com is the place to go.
They are right..
If you have any questions, please feel free to pm me.
I've done toll-free phone numbers for the past 10 years.
I've got numbers such as 866 real estate, 800 home 411, 800 certified, 800 tree expert etc.
The business is a lot like domaining.
However the problem is there are legal implications as stated above with hording and brokering phone numbers.
the Federal Communications Commission does not view phone numbers as property that can be owned by citizens.
They view phone numbers as "on lease".
Therefore you never really own the phone number.. you have what are known as "end user" rights, but you never technically own phone number.
Therefore, if you don't own it you can't sell it.
PM me and I'll be more than happy to tell you all about it.
thanks
Mark
