Actually no. From reading here[1] it appears anyone is allowed to ask
you your SSN and they can do what they like with it.
What you're describing is more like the TFN in Australia. Apart from
the fact you're not required to have one or provide it if asked, if
you're not a bank, or share registrary or some other such institution,
you're not allowed to ask for it, let alone store it. Medicare number
the same, if you're not a health service provider, you can't ask for
it.
Anyway, this doesn't mean an SSN is a good key, for all sorts of other
reasons people have already stated.
