How did he find me on Facebook?

Ok so I met this person I have never met before, we have zero mutual friends, and we did not know each other. Only thing he knew was my FIRST NAME and CELL NUMBER.

My first name is common, and my cell number is NO WHERE on my Facebook. Even if you search it, I don't pop up. I'm confused how this person found me on Facebook? He does not know anyone I know and I do not know anyone he knows...

Not a keeper, searching through over 500,000 people with the same first name, is creepy. He could of just asked me in a text to add him or for him to add me. This creeps me out.

More update:


No not from same city. I live almost 30 minutes away from where he does. My city/town or where I'm from is not posted on Facebook. (I'm very picky with posting stuff on Facebook, so I DO NOT).


I met him at a bar. He found me cute, took my number. Only said my first name. He only have like 70 Facebook friends. I searched through all of them, NONE are mutual or have friends I know of. So this is really creeping me out.


He added me on Facebook two days after we met.
