You have a "Licence Key" for Activation usually embedded on the Main Board.


Also it's best not to post those numbers, perhaps delete it.


Here's an article about it...


What is the reason for the question, a re-install  of the OS?


"KeyFinderInstaller" will tell the 'key'


If in doubt please ask.
