Conduct a Numident query to identify an invalid SSN. A Numident query is the most
reliable means of determining whether we assigned an SSN. If we never assigned the
SSN, the online message reads INVALID SSN. Also, identify invalid SSNs with:
-
•
The first three digits (former area number) as "000," "666,” or in the 900 series.
-
•
The second group of two digits (former group number) as "00."
-
•
The third group of four digits (former serial number) as "0000."
