Effective June 25, 2011, the Social Security Administration (SSA) will implement the SSN Randomization Project. The purpose of the SSA randomization initiative is to help protect the integrity of the SSN by establishing a new randomized assignment methodology. SSN randomization will also extend the longevity of the nine-digit SSN nationwide.
SSN randomization will affect the SSN assignment process in the following ways:
- It will eliminate 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.
- It will eliminate the significance of the highest group number and, as a result, the High Group List will be frozen in time and can be used for validation of SSNs issued prior to the randomization implementation date.
- Previously unassigned area numbers will be introduced for assignment excluding area numbers 000, 666 and 900-999.
The SSA will not reassign SSNs. Randomization will provide enough new numbers to avoid reassignment.
PMSI MMSEA Section 111 Reporting Clients
Changes will be made to the SSN validation process currently in place for claims submitted to MedicareConnectsm. After the new validations are implemented, existing claims will be revalidated. At that time, it is likely that error counts will be reduced, if the error was specific to the SSN composition.
PMSI recommends clients pull reports that contain the errors specific to SSN composition prior to the production release scheduled for June 23, 2011 if they intend to continue correcting this data.
The following new SSN validation rules will apply:
- The SSN should be nine digits in length
- SSNs with all zeros in any digit group (000-xx-####, ###-00-####, ###-xx-0000) are not allowed.
- SSNs with Area Numbers (First 3 digits) 000, 666 and 900-999 are not allowed.
- SSNs from 987-65-4320 to 987-65-4329 are not allowed as they are reserved for use in advertisements and are invalid (SSNInvalid Table contains all these SSNs).
- Cannot be on the list of invalid SSNs provided by SSA. These include SSNs which are invalid because they were used for advertisement or for fraudulent purposes.
