You file for Social Security Disability through the Social Security Administration, either online, by phone, or in person at your local office

The Social Security Administration (SSA) accepts applications for Social Security Disability Insurance (SSDI) through three routes: the SSA website at ssa.gov, by calling 1-800-772-1213, or by visiting your local Social Security office in person. The online route is fastest — you can start an process, save your progress, and return to finish it later. Phone applications take about 15 to 20 minutes. In-person applications at your local office take longer but may help if you have questions during the process.

Before you file, gather documents showing your work history, medical records, and proof of your condition. The SSA will ask for your Social Security number, birth certificate, and the names and dates of your doctors and hospitals. Having these ready speeds up the process. You do not need a lawyer to file, though some people hire one to help with the process or to represent them if the SSA denies the claim.

Key Takeaways

  • You can file online at ssa.gov, by phone at 1-800-772-1213, or in person at your local Social Security office.
  • Gather your Social Security number, birth certificate, medical records, and a list of doctors and hospitals before you start.
  • The SSA will ask detailed questions about your work history, your condition, and how your condition affects your daily life and ability to work.
  • The SSA typically takes three to five months to make a decision, though some cases take longer.
  • If the SSA denies your claim, you can request reconsideration or appeal within 60 days of the denial letter.

What documents you need before filing

Gather these documents before you start your process: your Social Security number, birth certificate, proof of citizenship or legal residency (passport, green card, or naturalization papers), and your most recent tax return or W-2. The SSA also needs a complete list of all jobs you have held in the past 15 years, including the dates you worked and the names of your employers.

For your medical records, write down the names, addresses, and phone numbers of every doctor, hospital, and clinic that has treated you for your condition. Include the dates of your visits if you have them. Bring copies of recent test results, imaging reports, or hospital discharge summaries if you have them. The SSA will request these records directly from your providers, but having them on hand helps you answer questions accurately during the process.

Filing online at ssa.gov

Go to ssa.gov and look for the "explore for Disability" button on the homepage. Click it and select "Start Your process Now." You will create a my Social Security account if you do not already have one. The account requires your email address, a password, and answers to security questions. Once your account is set up, you can begin the disability process.

The online form asks about your medical condition, your work history, your daily activities, and how your condition limits what you can do. You can save your progress and return to finish the process later — the SSA will hold your incomplete process for 60 days. Once you submit it, the SSA will send you a confirmation number by email. Write down this number and keep it with your records.

Filing by phone or in person

To file by phone, call 1-800-772-1213 Monday through Friday, 7 a.m. to 7 p.m. your local time. Have your documents ready before you call. The representative will ask the same questions as the online form and will take notes on your answers. At the end of the call, you will receive a confirmation number. Ask the representative to mail you a summary of what you reported so you can check it for accuracy.

To file in person, find your local Social Security office at ssa.gov/locator or call 1-800-772-1213 to make an appointment. Bring originals or certified copies of your documents. The office staff will help you fill out the process and answer questions about your work history and medical condition. In-person appointments typically take 30 to 45 minutes. You will receive a confirmation number and a receipt before you leave.

What happens after you file

After you submit your process, the SSA sends it to your state's Disability information Services (DDS) office. The DDS office reviews your medical records, contacts your doctors for more information, and decides whether your condition meets the SSA's definition of disability. This process typically takes three to five months, though some cases take longer if the SSA needs additional medical evidence.

You can check the status of your process by logging into your my Social Security account on ssa.gov or by calling 1-800-772-1213. The SSA will contact you if it needs more information — for example, if your doctors have not yet sent their records or if the SSA needs you to have a medical exam. Respond to these requests promptly, as delays can slow down your case.

Understanding the decision letter

The SSA will mail you a decision letter that says either "approved," "denied," or "approved for a different reason than you expected." If approved, the letter tells you when your benefits start and how much you will receive each month. Benefits typically begin the month after the SSA approves your claim, though some people receive back pay for months before the approval date.

If the SSA denies your claim, the letter explains why and tells you how to request reconsideration. You have 60 days from the date on the denial letter to ask for reconsideration or to appeal. Reconsideration means a different SSA examiner reviews your case. An appeal means a judge reviews your case at a hearing. Many people who are denied on the first process succeed on appeal, especially if they gather additional medical evidence.

If your claim is denied

Request reconsideration within 60 days of your denial letter. You can request reconsideration online at ssa.gov, by phone, or in person. Reconsideration is free and does not require a lawyer. The SSA will send your case to a different examiner who will review all the evidence again. Reconsideration typically takes two to three months.

If reconsideration is also denied, you can request a hearing before an Administrative Law Judge (ALJ). This is called an appeal. You have 60 days from the reconsideration denial letter to request a hearing. At a hearing, you can present evidence, answer questions, and have a representative speak on your behalf. Many people hire a disability lawyer for the hearing stage. Lawyers typically charge a fee only if you win, and the fee comes from your back pay rather than from your pocket.

Frequently Asked Questions

Can I file for SSDI if I am still working?

Yes, you can file while working. However, the SSA requires that your condition prevent you from doing substantial work — meaning earning more than a certain amount per month (the limit changes yearly). If you are earning above that limit, the SSA may deny your claim. If you are earning below it, you can file and continue working while your case is reviewed.

How much back pay will I receive if I am approved?

Back pay covers the months from when your disability began until the SSA approves your claim. The SSA calculates your benefit amount based on your work history and earnings record. The exact amount varies by person. Your approval letter will tell you how much back pay you will receive and when it will be paid.

Do I need a lawyer to file for SSDI?

No, you do not need a lawyer to file. Many people file on their own and are approved. However, if your claim is denied and you appeal to a hearing, a lawyer can help you present your case. Disability lawyers work on contingency, meaning they charge a fee only if you win, and the fee is taken from your back pay.

What if I do not have all my medical records?

You do not need to have all your records before you file. The SSA will request them directly from your doctors and hospitals. However, having as much medical evidence as possible helps your case. If you have recent test results or hospital records, include them with your process. If you are missing records, ask your doctors' offices to send them to the SSA after you file.

Can I file for SSDI on behalf of someone else?

You can help someone file, but they must sign the process themselves unless they are unable to do so due to their condition. If someone cannot sign, a representative payee (usually a family member or caregiver) can file on their behalf and manage their benefits once approved. Contact your local Social Security office for help with this process.
