WARNING On June 25, 2011, Social Security changed the SSN assignment process. The information below explains how we established and issued SSNs prior to the new SSN assignment process. We continue to provide it strictly for historical and informational purposes. Please see SSN Randomization for more 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. See also High Group List of SSN's.

THIS DATA IS STRICTLY FOR INFORMATIONAL PURPOSES

The chart below shows the first 3 digits of the social security numbers assigned throughout the United States and its possessions. The same area, when shown more than once, means that certain numbers have been transferred from one State to another, or that an area has been divided for use among certain geographic locations.
