HUD HCV Guidebook § 9.2.2

When adding a new household member who is under six years of age and does not have a SSN (for example,
when adding a newborn child to the assisted household), the participant must54 disclose and document the
SSN for the new member within 90 days of the child’s addition to the household. PHAs may grant a 90-day
extension if the failure to provide the information was beyond the family’s control (for example, if the delay
was due to delayed processing by the Social Security Administration (SSA), a natural disaster, or a death in the
family). A PHA must add the child to the assisted household pending submission of the SSN and the family
must receive all associated benefits and deductions. For submissions to the Inventory Management
System/Public and Indian Housing Information Center (IMS/PIC) system, PHAs must assign an “alternate ID”
to the child. PHAs must later replace the alternate ID with the child’s assigned SSN.
