SSA is proposing to change the way that we assign SSNs. We intend to eliminate the geographical significance of the first three digits of the SSN (the ``area number'') by no longer allocating entire area numbers for assignment to individuals in specific States. Instead, the SSN will be randomly assigned from the remaining pool of available SSNs, and the first three digits of the SSN will no longer have any geographical significance. We believe that by changing the way we assign the SSN we will ensure that there will be a reliable supply of SSNs for years to come. Additionally, we believe that this will also help reduce opportunities for identity theft and SSN fraud and misuse.
It seems to me that there may be more practical reasons behind this. A computer system that has to assign Social Security numbers both geographically and randomly is more complicated than one which assigns Social Security numbers merely randomly across the entire country.
This may sound silly, but I am already nostalgic for geographically assigned Social Security numbers.
