What is a requirement for applying for Supplemental Security Income (SSI)?

Applying for Supplemental Security Income (SSI) requires individuals to provide a Social Security card or a record of their Social Security number. This requirement is crucial because SSI is a federally funded program administered by the Social Security Administration, which uses the Social Security number to verify identity, eligibility, and other benefits associated with the program.

The Social Security number helps the administration track an individual's financial history and verifies their citizenship or immigration status, as residency is a primary eligibility factor for SSI. Therefore, the presence of a Social Security number is a fundamental requirement in the application process for SSI, ensuring that applicants can be correctly identified within the system.

In contrast, while the other options may be relevant in different contexts, they do not fulfill the core requirement for applying for SSI. Employment history isn't necessary, as SSI is designed to assist those with limited resources and income, including individuals who are not currently employed. Proof of home ownership or current medical insurance documentation may be relevant for other types of benefits or services but are not critical in the initial application for SSI.
