Symptoms

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:

• 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.

• 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. SSN's containing group number 00 or serial number 0000 will continue to be invalid.

• Randomization will also introduce previously unassigned area numbers for assignment, excluding area numbers 000, 666 and 900-999.

• System validates SSN entered by the user while hiring a person with the National ID formats that were setup in the system. If the format does not match with the defined format, system will throw a warning message to make sure that the users can re-enter the SSN correctly.
