According to the Social Security Administration, your nine-digit Social Security Number (SSN) is divided into three parts: 1. The first three digits are known as the area number. Until June 25, 2011, this is generally the State or territory where your SSN was assigned. Thereafter, the number was randomly assigned.
The first three digits of a person's Social Security number numbers can often help you to determine where your ancestor may have possibly been living when his/her SSN was issued (see exceptions below). These numbers can also be helpful in determining which listings in the SSDI may belong to your ancestor. The first three digits of a person's Social Security number were, prior to 1973, determined by the state where the person applied fo their social security card. Since that time, the first three digits have been assigned based on the ZIP Code of the mailing address on the Social Security number application.
