You apply for SSI through Social Security, not through a separate program
To start the process, you contact Social Security directly — either by phone, in person at a local office, or online through their website. Social Security handles both SSI and regular Social Security benefits, so when you apply, you'll be assessed for whichever programs you might be may be able to access for based on your age, disability status, and income.
The application itself asks about your living situation, income, resources, work history, and medical conditions. You'll need documents to back up what you report — birth certificate, proof of citizenship or legal residency, bank statements, and medical records if you're applying based on disability. Social Security will tell you what specific documents they need once you start the process.
Processing takes time. Most decisions come within three to six months, though some cases take longer if Social Security needs more information from you or your doctors. You can check the status of your application online through your Social Security account, by phone, or at your local office.

Applying online through Social Security's website
The fastest way to start is often through ssa.gov. You can begin an SSI application without leaving home, and Social Security will contact you to finish the process. Create a my Social Security account first — this lets you check your application status and manage your benefits later.
The online application asks basic questions about your age, living situation, income, and why you believe you need SSI. You don't upload documents during the online application; Social Security will ask for them later. Once you submit, Social Security sends you a confirmation number and tells you what happens next.
Online applications work well if you have a clear situation — you're over 65, or you have a documented disability and straightforward finances. If your case is complicated, starting by phone or in person might move things faster because you can explain your situation directly to someone who can ask follow-up questions.
Applying by phone or in person
Call Social Security at 1-800-772-1213 (TTY 1-800-325-0778 for deaf and hard of hearing callers). They're open Monday through Friday, 7 a.m. to 7 p.m. your local time. Have your Social Security number, birth certificate, and proof of citizenship or legal residency nearby when you call. The representative will walk you through the application and schedule an appointment if needed.
You can also walk into your local Social Security office without an appointment, though wait times vary. Find your nearest office at ssa.gov/locator. Going in person works well if you need help filling out forms, have questions about what documents to bring, or prefer to talk face-to-face.
Whether you call or visit in person, Social Security will schedule a follow-up appointment to collect documents and go over details. Bring everything they ask for to that appointment — missing documents delay your case.
What documents you'll need to gather
Start collecting these before you apply: your original birth certificate or certified copy, proof of U.S. citizenship or legal residency (passport, naturalization papers, or green card), and your Social Security number. You'll also need a photo ID issued by a government agency.
For income and resources, bring recent bank statements (usually the last two months), pay stubs if you work, and proof of any other income like pensions or unemployment benefits. If you own a car, you may need the title or registration. If you own property, bring documentation of that too.
If you're applying based on disability, gather medical records from doctors who have treated you — hospital discharge summaries, test results, prescription records, and notes from your most recent visits. You don't need to collect everything yourself; Social Security can request records directly from your doctors, but it moves faster if you provide them.
What happens after you submit your application
Social Security sends you a notice confirming they received your application. They'll contact you if they need more information — usually by mail, but sometimes by phone. Respond quickly to any requests; delays in sending documents can slow your case by weeks.
If you applied based on disability, Social Security may send you to a doctor they choose for an exam. This exam is free and helps Social Security understand your medical condition. You're not required to agree with the doctor's findings, but you should attend the appointment.
Once Social Security makes a decision, they mail you a notice explaining whether you were approved or denied. If approved, the notice tells you your monthly payment amount and when payments start. If denied, the notice explains why and tells you how to request reconsideration or appeal.
If Social Security denies your application
A denial doesn't end the process. You have the right to request reconsideration, which means Social Security reviews your case again with fresh eyes. You have 60 days from the date on the denial notice to request reconsideration. Submit this request in writing to your local Social Security office or online through your my Social Security account.
When you request reconsideration, send any new information or documents that support your case — updated medical records, new test results, or additional proof of income or resources. Reconsideration takes another two to three months.
If reconsideration is also denied, you can request a hearing before an administrative law judge. This is a more formal process where you can present evidence and argue your case. Many people hire a representative (lawyer or non-lawyer advocate) for a hearing. Social Security has a list of representatives on their website.
What to do while you wait for a decision
Keep your contact information current with Social Security. If you move, change your phone number, or change your mailing address, tell Social Security right away. Missing mail about your case can cause delays or problems with your benefits later.
Don't stop working or making changes to your finances just because you applied. Social Security looks at your situation at the time you apply and at the time they make a decision. If your income or resources change, report it to Social Security — hiding changes can cause problems later.
If you have questions while waiting, call Social Security or check your application status online. You can also visit your local office. Social Security staff can tell you what stage your case is in and what documents they're still waiting for.
Frequently Asked Questions
Can I apply for SSI if I'm already getting regular Social Security?
Yes. You can receive both SSI and Social Security retirement or disability benefits at the same time, though SSI payments are reduced by the amount of your other benefits. Social Security will assess you for both programs when you apply.
What if I don't have a birth certificate?
Contact your state's vital records office to request a certified copy. This usually costs $10 to $25 and takes one to two weeks. If you can't get a birth certificate, Social Security may accept other documents like a passport or naturalization papers as proof of age and citizenship.
Do I need a lawyer to apply for SSI?
No. You can apply on your own without paying anyone. However, if Social Security denies your application and you appeal, having a representative can improve your chances. Social Security limits what representatives can charge — currently $6,000 or 25% of your back pay, whichever is less.
What if my income or resources change after I apply?
Tell Social Security right away. Changes that happen after you apply can affect whether you're approved and how much you receive. Social Security won't penalize you for reporting changes honestly.
How long does it take to get my first payment?
If approved, your first payment usually arrives one to two months after Social Security makes the decision. The exact timing depends on when in the month you're approved and how Social Security processes your case. Your approval notice will tell you when to expect your first payment.
