5 093 are in service. I have backed up my claim with Chinese source which is more crediable than RevolvingPersonalityConduct's US Department of Defense Source. 093 is a Chinese SSN 

Hello Iwilsonp, I have added sources to the 093 page. Please protect that page from RevolvingPersonalityConduct. He is an online troll whom repeatedly vandalize Wikipedia pages !

Thank you
