Summary of US Legislative Change: 

The Social Security Administration (SSA) is changing the way Social Security Numbers (SSNs) are issued. This change is referred to as "randomization." The SSA has developed this new method to help protect the integrity of the SSN.  In addition, SSN Randomization will also extend the longevity of the nine-digit SSN nationwide.  The SSA implemented the new assignment methodology on June 25, 2011. 

The changes that will result from randomization include the following: 

  1. The elimination of the geographical significance of the first three digits of the SSN, currently referred to as the area number, by no longer allocating the area numbers for assignment to individuals in specific states.
  2. The significance of the highest group number (the fourth and fifth digits of the SSN) for validation purposes will be eliminated. SSN randomization will not assign group number 00 or serial number 0000.  SSNs containing group number 00 or serial number 0000 will continue to be invalid. 
  3. Randomization will also introduce previously unassigned area numbers for assignment, excluding area numbers 000, 666 and 900-999.
