Please document how the id of a randomuser is generated, or can be interpreted.

Hello,
when generating users they do by default include an object named id, which looks like the following

{name: 'SVNR', value: '68 160549 B 117'}

How can this id be interpreted? Or what is the theoretical concept, which guarantees, that they are really unique?

I want to generate social-network-like clusters of users, which persist a collection of id's of other users, which would represent their contacts and considered to use this id instead of the login.uuid.
