How to apply

You can apply for SSI online, by phone, or in person at an SSA office. Adults aged 65 or older can apply online in full; disabled and blind adults generally start online or by phone and complete the application with an interview; children's applications usually begin by phone or in person. Whichever route you take, the application date matters: if you are approved, back payments generally start from your application date, not from when your condition began.

Routes and what happens next

Online: the fastest route for those who can use it — the application for aged claimants is fully online, and disability applicants can start online and finish with a phone interview. By phone: call SSA's national number and book an appointment; an interviewer takes the application with you. In person: visit a local SSA office, ideally with an appointment. After you apply, SSA checks the non-medical rules (income, resources, residence) and, for disability claims, sends the medical part to the state Disability Determination Services for a medical decision.

Decisions can take several months — this site gives no hard promise on timing, because medical evidence gathering varies widely. You can check the status of your application online or by phone, and you should respond quickly to any request for documents: a slow response is one of the most common causes of delay.

Documents to gather

• Identification and, if applicable, immigration documents
• Social Security numbers for you (and your spouse, for couples)
• Bank statements and records of what you own (accounts, vehicles, property)
• Pay stubs, pension and benefit letters, and any other income records
• Rent or mortgage details, and who pays your household costs
• Medical records, doctor and hospital contacts, and school records for children
• Marriage or divorce papers, if relevant

Do not delay applying because a document is missing — apply first and supply the rest afterwards. SSA will tell you exactly what it still needs.

Representative payees

If SSA decides you cannot manage your own payments — because of age, a condition, or another reason — it appoints a representative payee, usually a family member or a trusted organization, to receive and spend the payment for you. A payee must use the money for your needs, keep records, and report to SSA. If you disagree with a payee decision, or with who was chosen, you can appeal. Payees are a protection, not a punishment, but they do change who controls the money — so the choice of payee deserves care.
