Does the UDID ever change?


I thought this was a unique # but I did read that the UDID is interchangeable just like a Computer's MAC address, based on the logic apple currently applies to get the UDID#.


My iPad UDID definitely changed as I didn't purchase a new iPad, I was using this as a Unique # to store in our main system's DB to keep track of what the last Order # for that device (each device as a order range).

Can anyone confirm this? I'm trying to find a solution, if anyone has any advice it'll be greatly appreciated.
 
You haven't been able to rely on the UDID for a looooong long time.
It's even against the rules trying to track the hardware.
