Note that this number resides in normal program memory, and it will be erased if you erase the part for reprogramming. Edit The reason controllers most often don't have this at chip level is that it's expensive: the programming is done by lasering, which is an extra production step. Mass-programmed microcontrollers can easily have the unique ID programmed with the software, and this doesn't require an extra step.
An alternative would be an SSN (Silicon Serial Number) like the Maxim. These are also laser-programmed, so not cheap either, but you avoid the extra logistic steps, where there can always go something wrong. How To Play Chess Endgames Download. I've known it happen.
