I wonder how close we are to running out. We have 300 million in the country, but some are illegals without numbers. But I don't think they reuse numbers of the dead, so everyone who's lived counts toward the 1 billion limit right?
Another thing I am not sure about, what happens to the SS # of someone who dies? Does it go to a trash heap never to be used again? If so, then we would be steadily eating into the supply of 9 digit #'s till we run out and some kind of addition made, maybe a letter prefix or something, that would bump the available up to 26 odd billion, enough for the whole planet, eh.
