The process process has three routes, and the fastest one depends on your situation

You can file for Social Security Disability Insurance (SSDI) online through the Social Security Administration website, by phone, or in person at your local Social Security office. The online route is usually fastest—you can start an process at ssa.gov/applyfordisability and finish it in one sitting, though you will need to upload medical records later. By phone, you call 1-800-772-1213 (TTY 1-800-325-0778) and a representative walks you through the questions. In person, you visit your nearest Social Security office with your documents and complete the process with staff help.

Whichever route you choose, the Social Security Administration will ask the same questions and request the same documents. The difference is mainly in how long you wait on hold and whether you can do it from home. Most people who file online report the fastest decisions, because the form is submitted when ready and there is no transcription step.

Key Takeaways

  • You can file online at ssa.gov/applyfordisability, by phone at 1-800-772-1213, or in person at your local Social Security office.
  • You will need your birth certificate, proof of citizenship or legal residency, medical records from your doctors, and a list of your medications and dosages.
  • The Social Security Administration typically makes an initial decision within three to six months, though some cases take longer if they need more medical evidence.
  • If you are denied, you can request reconsideration, which sends your case to a different reviewer, or you can appeal to an administrative law judge.

What documents to gather before you start

Have these items ready before you begin the process, whether online, by phone, or in person: your Social Security number, birth certificate, proof of U.S. citizenship or legal residency (passport, green card, or visa), and your most recent tax return or W-2. You will also need the names and addresses of all doctors, hospitals, and clinics that have treated you for your condition, plus the dates you saw them.

Medical records are the most important piece. Gather recent reports from your doctors—test results, imaging scans, lab work, mental health evaluations, or hospital discharge summaries. If you have not seen a doctor in months, the Social Security Administration may ask you to get an examination before they decide. You do not need to submit everything at once; you can upload records after you file the initial process.

Make a list of every medication you take, including the name, dosage, and how often you take it. If you have been hospitalized or had surgery related to your condition, gather those records too. The more complete your medical history, the faster the Social Security Administration can make a decision.

How to file online at ssa.gov

Go to ssa.gov/applyfordisability and click "explore Now." You will create a my Social Security account if you do not have one already—this requires your email address and a password. The system will ask you to verify your identity by answering security questions or uploading a photo ID.

Once you are logged in, the process walks you through your personal information, work history, medical conditions, and doctors' names. You can save your progress and come back later if you need to. When you reach the end, you will see a summary of what you entered. Review it carefully, then submit.

After you submit, the Social Security Administration will send you a confirmation number and tell you what happens next. Within a few days, you will receive a letter in the mail asking you to upload your medical records and other documents. You can do this through your my Social Security account or by mailing them to the address in the letter. Do not wait to be asked—upload them as soon as you can.

Filing by phone or in person

To file by phone, call 1-800-772-1213 between 7 a.m. and 7 p.m. Monday through Friday. Have your documents nearby so you can answer questions about your medical history and work. The call usually takes 30 to 45 minutes. At the end, the representative will mail you a confirmation letter with your process number.

To file in person, find your local Social Security office at ssa.gov/locator or call the same number. Walk-ins are accepted, but wait times can be long. You can also call ahead to schedule an appointment, which usually gets you in within a week or two. Bring all your documents—originals or certified copies—and be prepared to spend an hour or more at the office.

What happens after you file

The Social Security Administration sends your process to a Disability information Services office in your state. This office reviews your medical records and decides whether your condition meets the Social Security Administration's definition of disability—meaning you cannot work for at least 12 months or have a condition expected to result in death.

The review usually takes three to six months, but can take longer if the office needs more information from your doctors. You may receive a letter asking you to attend a medical examination paid for by the Social Security Administration, or asking your doctor to send additional records. Respond to these requests as quickly as you can, because delays slow down the decision.

You will receive a decision letter in the mail. It will say you are approved, denied, or approved for a different benefit than you requested. If you are approved, the letter will tell you when your benefits start and how much you will receive each month.

What to do if you are denied

If the Social Security Administration denies your claim, you have the right to challenge the decision. You have 60 days from the date on the denial letter to request reconsideration, which sends your case to a different reviewer at the Disability information Services office. This person looks at your file fresh and can reach a different conclusion.

If reconsideration is also denied, you can request a hearing before an administrative law judge. This is a formal process where you can present evidence and testimony. Many people hire a disability lawyer or advocate for this step, because judges are more likely to approve cases when someone represents you. Lawyers typically take their fee only if you win—usually 25 percent of your back pay, up to a maximum set by the Social Security Administration.

The entire appeal process can take one to three years. During this time, you can continue to work and earn income, but if you eventually win, your benefits will be backdated to the date you first filed.

How much you will receive each month

Your monthly SSDI payment is based on your earnings record—specifically, how much you earned during your working years. The Social Security Administration calculates an average and applies a formula. The average payment in 2024 is around $1,550 per month, but yours could be higher or lower depending on your work history.

You can see an estimate of your future benefits by creating a my Social Security account and viewing your earnings record. This also shows how much you have paid into Social Security through payroll taxes. If you have not worked much, your payment will be lower. If you have worked steadily for many years, it will be higher.

Once you start receiving SSDI, you can earn a limited amount of money from work without losing benefits. This is called the trial work period. After nine months of trial work, the rules change and you may lose some or all of your benefits if you earn above a certain amount. The Social Security Administration will explain these rules in detail when you are approved.

Frequently Asked Questions

Can I work while my process is being reviewed?

Yes. Working does not disqualify you from SSDI, and it does not slow down your process. However, if you earn more than a certain amount per month (called substantial gainful activity), the Social Security Administration may use that as evidence that you can work and deny your claim. Keep records of your earnings and any work limitations you experience.

What if my doctor has not documented my condition thoroughly?

Contact your doctor and ask them to send updated records to the Social Security Administration. You can provide the doctor with the address from your process letter. If you have not seen a doctor recently, schedule an appointment and bring a copy of your process so the doctor understands what information is needed. The Social Security Administration may also order a consultative examination at no cost to you.

How long does it take to get my first payment?

If you are approved, your benefits usually start the month after the Social Security Administration makes the decision. Your first payment arrives by direct deposit or check within a few weeks. If your process takes six months to decide, your first payment could arrive seven months after you filed.

Can I explore for SSDI and SSI at the same time?

Yes. If you have limited work history or low income, you may be able to receive Supplemental Security Income (SSI) while your SSDI process is being reviewed. You can file for both at the same time, and the Social Security Administration will process them together. SSI has different rules and lower income limits, so you may be approved for one but not the other.

What if I disagree with the medical evidence the Social Security Administration used?

You can submit your own medical evidence at any stage—during the initial process, during reconsideration, or during an appeal. If you have newer test results, a letter from your doctor explaining why you cannot work, or records from a specialist, send them to the Social Security Administration when ready. This new evidence can change the outcome of your case.
