I don't think you can in the sense of making sure you have
a valid SSN. MIBEN's function will guarrantee that you
have the right pattern.

I KNOW that the last three digits are assigned sequentially
(as a matter of fact, you can use them to perform a random
selection from the SSN.......).

I have been told that the first 3 and middle 2 digits mean
something. Something about where in the country it was
issued, but I don't know what it is.


Good Luck
