On June 25, 2011, the Social Security Administration changed how it assigns Social Security numbers. The information below explains how SSNs were established prior to the new assignment process. We continue to provide it strictly for historical information on Social Security’s new assignment process and how it may affect you.
“Since 1973, social security numbers have been issued by our central office. The first three (3) digits of a person’s social security number are determined by the ZIP Code of the mailing address shown on the application for a social security number. Prior to 1973, social security numbers were assigned by our field offices. The number merely established that his/her card was issued by one of our offices in that State”
This chart shows the first three (3) digits of the Social Security numbers assigned throughout the United States and its possessions. (See Note)
