The DoD ID Number as PII
By DoD White Paper - Published, August 16, 2019
The SSN has been used throughout the DoD as a means to identify and authenticate individuals and its expanded use has increased efficiency, enabling DoD information systems and processes to interoperate and transfer information with a greatly reduced chance of errors. However, the threat of identity theft has rendered this widespread use unacceptable, resulting in the requirement that all Federal agencies evaluate how the SSN is used and to eliminate its unnecessary use where possible.
One effort initiated to reduce the use of the SSN is to replace it with the number now known as the DoD ID number (formerly the EDI-PI). The attached DoD white paper will explain how the DoD ID number should be used in and, in rare cases, outside of DoD.
