So this guy gave me his number?

[Denima]

Ok so this guy gave me his number at work yesterday, and I will admit he wasn't bad looking and did make me laugh. Anyway, I know near to nothing about him and I would love to know if there's anyway for me to find his name with just a mobile number, seeing as weirdly enough he didn't give me his name. I searched it on Facebook but to no avail and it's an Australian number so the reverse number sites don't work. I just wanna know this guys name without giving him my number you know? I was wondering if I could put it in my contacts and maybe see if there's an app that find people's Facebook through your contacts but I don't really know haha, Thankyou for any answers
