SSN numbers are good for 999,999,999 people alive or dead. At some point the US will hit that, right? Do we start reusing numbers? Sounds like a disaster waiting to happen.

Why not?
Reserved for employer identification numbers.
Or newborn babies. I still got a 950 number written on the back of my official birth certificate.
Interesting, never heard of that. I’ve certainly obtained EINs that begin 95-…
I don’t make the rules, but here ya go…

I think they’re used as placeholders while they file the documents. My OG SS number started with 950, but that only lasted until the paperwork was complete.
Obviously I won’t be sharing my private info here though, but yeah, those numbers can’t officially start with a 9.
There are several more that aren’t used. There are a few reserved for promotions or movies and such. 666, 900-999 and 000 numbers are out as well.
I believe that SSNs have to pass a luhn check too.
But that would mean there’s already duplicates in use as you’d be limited to 90 million rather than 900 million.

From the second.
Yeah, personally, I have questions about the luhn check myself. (I am not in a state to research more this evening, unfortunately.)
I’ll save you the bother. It doesn’t have one. :)
If it did, there wouldn’t be enough numbers for everyone to have a unique one.
