Executive Order 13478

Amendments To Executive Order 9397 Relating To Federal Agency Use of Social Security Numbers

This executive order amends a 1943 order on federal use of Social Security numbers, making agency use permissive ('may' rather than 'shall'), updating outdated agency names and legal citations, and adding standard disclaimers about legal enforceability and appropriations availability. It does not impose new privacy restrictions or operational requirements.

Key directives

  • Replace 'shall' with 'may' in E.O. 9397 paragraph 1 regarding agency use of SSNs
  • Remove 'exclusively' from SSN use description
  • Update legal citation from Title 26, section 402.502 to title 20, section 422.103
  • Remove 'the 1940 Supplement to' reference
  • Replace 'Bureau of the Budget' with 'Office of Management and Budget'
  • Renumber paragraph 6 as paragraph 8
  • Add new paragraphs 6 and 7 on implementation subject to law/appropriations and no private right of action
  • Replace 'Board' with 'Administration' throughout

Timeline

Risks & tensions

  • Permissive 'may' language weakens prior mandatory obligation, though practical effect unclear given 65 years of established practice
  • No new privacy safeguards added despite policy statement on protecting personal identifiers
  • Standard OMB/litigation disclaimers (paragraphs 6-7, Section 3) limit accountability mechanisms
