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.
For example, 123-45-6789. The first three digits of the SSN are the area number. For numbers assigned prior to 1973, the area number indicates the specific Social Security office from which the card was issued. After 1973, blocks of numbers were allocated to each state.
