Guidance: States are reminded that CCDF eligibility may not be denied because a parent chooses not to provide their Social Security Number. (See ACYF-PI-CC-00-04 issued October 27, 2000). The Bureau requires that SSN's of children in protective service cases be reported in place of the head of the family (element #3), if a SSN is provided. If no SSN is provided, the unique identifier identifies the child, not the head of the family. This requirement ensures that the system will not generate missing data error messages and allows the system to match for longitudinal research studies.
