INVALID SOCIAL SECURITY NUMBERS

From Judy
The letter "A" means that she received social security monthly benefits on her own work record (an "A" signifys worker's account) - a "B" would have meant that she was receiving a monthly benefit as a wife on her husband's record. This "B" is converted to a "D" if she were widowed. There are about a 100 different combinations of letters/numbers to represent different types of benefits payable. Those with B's, C's, D's and E's are preceded by the worker's social security number (not the recipients number).
Hope this helps - Judy (an employee of Social Security Adm.)

From Linda Thiessen
The "-A" behind a Social Security Number may mean the following-they are all similar:

1) "Years ago when SS first began most women, unless they worked outside the home did not have their own # so "-A" was added to the husbands number for the wife. She was not a wage earner, but they still needed to keep a record for her thus the "A"".

2) "They are a Medicare designation - indicating a Medicare status and the actual SSN was not the same as this number".

3) "Women who did not work outside the home were given their husband's SS# with "A" attached when they became eligible for retirement benefits. This was her #".

4) "May indicate more than one person receiving some type of benefit under this number-husband and wife"


Also reasons given from Social Security Administration for not finding relatives on the SS death index:
Not everyone will be listed on Death index's unless 1) benefits were paid and 2) the person receiving the benefits has died.



Some more information on additional letters
A social security number with an "A" after it - designates the working individual
Followed by the letter "B" - this is the wife of the working individual
Followed by a "B1" - this is the husband of a working individual
Followed by a "C", plus a number (1,2, etc) - child of the working individual
Followed by a "D" - widow of the working individual (a "B" is converted to "D" in event of death of the worker)
The possible combinations of letter's, plus numbers is quite long.
