RPi server licensing and recovery question

Hi. Does the server Serial Number VirtualHere uses on Raspberry Pis change with reinstallation of Linux, or does it stay consistent on the same hardware? If I reinstall Linux, or switch between the different versions of Linux, can I then simply enter my activation code for the server again or would I need to contact support every time? Is there a difference between the different models of Raspberry Pi?

Stays consistent with the same hardware. Just put in the license key again and it will work. If you switch using cloudhub it does require a different key.
