Compile and maintain identifiable records with Social Security Numbers only when required by law

SSN2: New collection processes or new research grants effective on or after July 1, 2017: Identifiable records containing full SSNs may be compiled and maintained only to comply with a specific legal requirement. Full SSNs plus identifiable information may only be used or printed in documents where it is legally required. Identifiable records with full SSNs may not be compiled or maintained if there is no legal requirement for that specific data. For example, maintaining full SSNs only as a tool for differentiating records does not satisfy a legal requirement; the same purpose could be...
