I got this recently. Is this a sign of the new re-recon? If it is, I don't expect it to amount to much. This sort of thing doesn't seem like a priority. Even if it were, the staffing isn't there to do much.
By the way, notice that "DDS Case Number." It wasn't the claimant's Social Security number. Is this a sign that Social Security itself will start moving away from the use of the Social Security number as much as possible?
