Facebook Inc (NASDAQ:FB) will celebrate its ten years of existence on February 4 this year. To celebrate this event, The Guardian has revealed the first ten users of what was initially known as “The Facebook.” The company co-founder Mark Zuckerberg was the fourth user of the social network he co-founded. That’s because he had reserved the first three accounts for testing.

In the beginning, everyone on Facebook Inc was given a user ID number when joined. The first few million users were numbered on the basis of university. For example, 0-99999 were assigned to Harvard users, 100000-199999 were strictly for Columbia users, 200000-299999 were for Stanford users, and so on.
