When must Social Security numbers be disclosed and documented for applicants?

The requirement to disclose and document Social Security numbers for applicants is crucial in the eligibility determination process as it ensures compliance with federal regulations and helps in verifying identities. This step is essential to thoroughly assess an applicant's eligibility for housing programs.

Gathering Social Security numbers at the time of eligibility determination facilitates accurate record-keeping, helps in cross-referencing with various databases for verifying income and family composition, and provides a means to ensure that applicants are not receiving duplicate benefits across different programs. This can prevent fraud and promote fair access to housing resources.

Other choices aren't correct because asking for Social Security numbers During pre-application may not allow for proper verification, and waiting until after admission could lead to complications such as delays or issues in accurately documenting an applicant’s eligibility before they receive benefits. Thus, the timing around eligibility determination serves as the appropriate moment for this requirement.
