    RDD sampling frames are designed so that you can only randomly dial a phone number within a designated landline prefix (the first three digits of your number). It's done that way because cell phone users effectively pay for the phone call whether or not they make the call themselves, whereas landline users don't pay for incoming calls.

    Of course, now that numbers are portable, the distinction between landline and cellular exchanges is breaking down, which further contributes to the problem.

    •  Thanks! It still seems goofy to me that (1+ / 0-)

      some polling outfit wouldn't do this anyway---or do some version of it---if it made their product better.

      Or is there actual legislation that makes this illegal?

      [And I'm betting it's becoming clearer and clearer that chrississippi is living without a cell phone contract . . . ]
