That's not completely true. If you're in an old Ameritech area in Ohio, pick up the phone, dial '0' and when the Operator comes on, say: "OBT-125, please read number on display." You'll get the NPA-NXX-XXXX read out to you and she'll tell you to have a good day. As of three years ago, you could call any of the embarq/sprint area operators in Ohio/Kentucky and just say, "ID Me." Phone phreaking is still alive, but, it's not as common as it once was.
