Tested most of the numbers on the useful phone numbers page located HERE
Crossed out all numbers that no longer work, or no longer provide the function they are listed for.
Numbers remain (but crossed out) for historical, and archival purposes. As phone numbers can eventually be reassigned, please refrain from calling the crossed out numbers, unless there is a reason to do so, as I have personally confirmed they no longer function as specified, and may no longer belong to the same owner. The owner of a toll free number pays for incoming minutes, so be reasonable.
