Dennis, Almost, but not quite. Gallup apparently is dialing semi-random numbers. Some of them link to listed people, some link to unlisted numbers, and some link to businesses. Some don't link.
Gallup still can't find out the number of a person whose phone is unlisted. You could dial numbers at random, as well as they, and get the same sorts of unlisted people. Of course, they have a machine that does this..... dennis roberts wrote: > one paragraph in the description is rather disturbing ... > > ------------- > > The computer program then takes each phone exchange selected and "creates" > an actual 10-digit phone number by adding random digits to the exchanges. > There is no such thing as an unlisted phone exchange, so the randomly > created phone numbers include unlisted as well as listed numbers.
