I was filling out the ol' 4473 this weekend and noticed something that had I had always passed over. There is a spot to put your SS# but it states that it "isn't necessary but helps with identification". What on Earth does this mean? Does anyone know what use your Social Security number could possibly play in the process? They don't read your SS# to NICS obviously, so why do they ask for it voluntarily? They aren't documenting your purchases by your SS# are they?
