Deciphering SS #'s -informational purposes only
I saw this and thought it might be useful in some of the cases here.
The Social Security Number (SSN) is composed of 3 parts,XXX-XX-XXXX, called the Area, Group, and Serial. For the most part, (there are exceptions), the Area is determined by where the individual APPLIED for the SSN (before 1972) or RESIDED at time of application (after 1972). The areas are assigned as follows:
000 unused 387-399 WI 528-529 UT
001-003 NH 400-407 KY 530 NV
004-007 ME 408-415 TN 531-539 WA

The fourth and fifth digits of the SSN (the group number) are assigned sequentially, and knowing when that particular state reached that number, can give you a time frame as to when the SSN was assigned, hence a place and time of residence.
When searching the Social Security Death Index (SSDI), you can focuss your sort If you know where the person was from. For instance, if you are looking for a Joe Jones and you know that he always lived in Utah, then you can enter that state and your results will show all persons in the death index named Joe Jones who were issued a SSN from Utah. Knowing a birth date will help in narrowing the search even more, but keep in mind that mistakes can be made in data entry, or in memory of those who report the death.
Social Security Numbers are protected from release by Federal offices and by many (if not all) state offices. This is becoming more and more an issue due to problems with identity theft, and higher security concerns. Once a person dies, however, his or her SSN is no longer covered by any Privacy Act laws. In fact, it is published within a month on the SSDI.
