How to Get a Facebook Page Code?

[Happy Panda]

Ok, so on Facebook I`ve seen some pages with codes or IDs like [@0:360396305913] or something like that. So, I was wondering how you make/get one of those codes for my Facebook Page. Thanks ^_^

if you save the profile picture its name is the picture, or at least thats what it used to be with people

edit:find a page where you know the id and compare the id with the profile picture filname, its hidden somewhere in there
