As others have suggested, many companies do still have SSNs stored as packed 
decimal. So sure, a namespace expansion is possible, but it's a bigger change 
than one might think, however it's done. I've even seen at least one company 
who stored them as binary! I sure hope someone got a big bonus for saving that 
byte...

They use the same namespace--that is, if your SSN is 123-45-6789, an estate or 
business could also have that number. Since they're uses for different things, 
it's more that they happened (!) to choose the same format than that they're 
"the same". (And actually they're theoretically formatted differently: an EIN 
is xx-xxxxxxx vs. the SSN xxx-xx-xxxx, not that most folks store them with the 
hyphens.)
