social security number

The Social Security Administration (SSA) changed the way Social Security Numbers (SSNs) are issued on June 25, 2011. This change is referred to as “randomization.” The SSA developed this new method to help protect the integrity of the SSN. SSN Randomization will also extend the longevity of the nine-digit SSN nationwide. We are in the process of updating this article accordingly.

About Social Security Numbers

In the United States, a Social Security number (commonly known as SSN) is a number issued to U.S. citizens, permanent residents, and people that are temporarily working in the country. The number is issued to an individual by the Social Security Administration, an agency of the federal government. Its primary purpose is tracking working individuals for taxation purposes and to track Social Security benefits. Since it was initially introduced, the SSN has become the primary national identification number, even though it was not originally indended to be used as a form of identification.

There is no law directly requiring a natural born United States citizen to apply for a Social Security number, or SSN, to live or work in the United States.  Although some people still live without a Social Security number, it is becoming ever increasingly difficult to engage in normal acts of commerce or banking activities without providing an SSN. Such prohibitions against persons that refuse to enter into what amounts to a voluntary government program, raises a variety of constitutional concerns.

Since 1972, social security numbers have been issued by the central office of the  Social Security Administration. 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 1972, social security numbers were assigned by Social Security Administration field offices.  The number merely established that his/her card was issued by one of the Social Security Administration offices in that State.

In 2011, the Social Security Administration (SSA) changed assignment process to a process known ad SSN randomization. This process eliminates the geographical significance of the first three digits of the number.

Social Security Number – Area Group Serial

The Social Security number consists of nine (9) digits, usually written in the format – 1 2 3 – 4 5 – 6 7 8 9. The first three digits of a social security number denote the area (or State) where the application for an original Social Security number was filed.

Within each area, the group number (middle two (2) digits) range from 01 to 99 but are not assigned in consecutive order. For administrative reasons, group numbers issued first consist of the ODD numbers from 01 through 09 and then EVEN numbers from 10 through 98, within each area number allocated to a State. After all numbers in group 98 of a particular area have been issued, the EVEN Groups 02 through 08 are used, followed by ODD Groups 11 through 99.

Within each group, the serial numbers (last four (4) digits) run consecutively from 0001 through 9999.

This chart below shows how Group numbers are assigned:

  • ODD – 01, 03, 05, 07, 09——EVEN – 10 to 98<
  • EVEN – 02, 04, 06, 08——ODD – 11 to 99

  1. i have a question it says the 1st 3 numbers say where one was born i have 149 the list says that is the number for new Jersey and i was born in Oklahoma. why?

    • The first three numbers actually represent the geographic area where the social security number was issued, rather than where a person was born.
