Verifying Social Security numbers for all adults is essential because SSNs are the unique identifier used by HUD to confirm each household member’s identity and to check eligibility records. This verification helps ensure that the right person is linked to the right benefits, prevents duplicate participation across programs, and supports accurate income and eligibility determinations by cross-referencing with SSA and HUD databases. Date of birth alone won’t reliably identify a person or prove eligibility, since many people share birth dates and it doesn’t provide a cross-check against official records. Employer contact information isn’t a standard factor used to determine eligibility, and residency status, while relevant in some contexts, does not by itself establish eligibility for most HUD programs. So, the required information for all adults is the Social Security number.
