Not only that, but you basically need to program in all the random numbers you do business with to make sure you don't miss something important. Dentist, doctor, real estate agent, mortgage officer, the random office you're only going to visit once who did your MRI. And still, someone can just as easily spoof one of those numbers (even purely by coincidence) and you'll pick up.
