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 number is divided into three parts. The Area Number, the first three digits, is assigned by geographical region. Prior to 1973, cards were issued in local Social Security offices around the country and the Area Number represented the office code where the card was issued.
