The SS-5 form is the form a person fills out to apply for a social
security
number. These forms are available for deceased individuals and can be
obtained
from the Social Security Administration. They can be an excellent
genealogical
source. The person does not have to be in the SSDI (Social Security
Death Index) in order for a
person to obtain the SS-5 form. Anyone who had a Social Security Number
completed an SS-5 form.
