What happens when you sign up for SSDI

When you sign up for SSDI, you are submitting a claim to the Social Security Administration (SSA) that you have a medical condition severe enough to prevent you from working. The SSA will assign your claim a number, send you a receipt notice, and begin gathering medical records from your doctors. You will not hear back about approval or denial for several months — the average wait is three to five months, though some cases take longer.

Signing up does not cost money and does not obligate you to anything. If your claim is denied, you can appeal. If you are approved, your benefits begin the month after you have been disabled for 12 months (this is called the waiting period). The whole process is free; SSA does not charge you to file.

Key Takeaways

  • You can sign up for SSDI online at ssa.gov, by phone at 1-800-772-1213, or in person at your local Social Security office.
  • You will need your Social Security number, birth certificate, W-2s or tax returns from the past year, and a list of all doctors and hospitals that have treated you.
  • The SSA will request medical records directly from your doctors; you do not have to collect them yourself, though you can speed up the process by providing them.
  • After you sign up, you will receive a receipt notice with a claim number; use this number to check the status of your claim online or by phone.
  • The decision process typically takes three to five months, and you will be notified by mail whether you are approved, denied, or need to provide more information.

Three ways to sign up

Online at ssa.gov is the fastest route if you have a computer and internet. Go to ssa.gov/applyfordisability, create or log into your my Social Security account, and follow the form. You can save your progress and come back later. The form asks about your medical condition, work history, and doctors. Once you submit, you will receive a receipt notice by mail within two weeks.

By phone at 1-800-772-1213 (TTY 1-800-325-0778) connects you to an SSA representative who will ask the same questions and file the claim for you. Call between 7 a.m. and 7 p.m. Monday through Friday. Wait times are longest early in the week and early in the morning. You will still receive a receipt notice by mail.

In person at your local Social Security office is an option if you prefer to speak face-to-face or need help filling out the form. Find your office at ssa.gov/locator. Bring the documents listed below. You do not need an appointment at most offices, but calling ahead can reduce your wait time.

Documents you need before you sign up

Have these items ready before you start, whether you are filing online, by phone, or in person:

  • Your Social Security number
  • Your birth certificate or other proof of birth date
  • Your W-2 forms or tax returns from the past year (to verify your work history)
  • A list of all doctors, hospitals, and clinics that have treated you, including their names, addresses, and phone numbers
  • The dates you last worked and the names of your employers for the past 15 years
  • Information about any medications you take

You do not need to bring medical records with you. The SSA will request them directly from your doctors. However, if you have recent test results, imaging reports, or specialist letters that clearly describe your condition, you can submit them yourself to speed up the process. You can mail them, upload them through your my Social Security account, or bring them to your local office.

What the SSA does after you sign up

Once your claim is filed, the SSA sends you a receipt notice within two weeks. This notice has your claim number on it — save this number because you will use it to check your claim status. The SSA then requests medical records from every doctor and hospital on your list. This step usually takes four to eight weeks.

While the SSA is gathering records, a disability examiner is assigned to your case. The examiner reviews your medical evidence and work history to decide whether your condition meets SSA's definition of disability. If the examiner needs more information — for example, a recent test result or clarification from your doctor — they will contact you by mail and ask you to provide it within 10 days.

You can check the status of your claim online at ssa.gov/myaccount or by calling 1-800-772-1213 and providing your claim number. The SSA will tell you whether they are still gathering records, whether they have sent a request for more information, or whether a decision has been made.

Timeline from sign-up to decision

The typical timeline is three to five months from the day you sign up to the day you receive a decision. However, this varies. Cases with straightforward medical evidence — for example, a recent cancer diagnosis with clear treatment records — may be decided in six to eight weeks. Cases that require multiple requests for records or additional medical exams may take six months or longer.

If your case is assigned to a Disability information Service (DDS) office in your state, the wait may be longer during busy periods. Some states have backlogs that push decisions to six or seven months. You can ask the SSA whether your state's DDS is currently experiencing delays when you call to check your status.

What happens after you receive a decision

The SSA will mail you a decision notice. If you are approved, the notice will tell you the month your benefits begin. Remember that there is a five-month waiting period — you must have been disabled for 12 months before benefits start, so your first check will not arrive for at least 17 months after you sign up (12 months of disability plus five months of waiting). If you have been disabled for longer than 12 months already, your waiting period may be shorter or already complete.

If you are denied, the notice will explain why. You then have 60 days to file an appeal. The most common reason for denial is that the SSA does not believe your medical condition is severe enough to prevent all work, or that you did not provide enough medical evidence. If you appeal, you can request a hearing before an administrative law judge, which gives you a chance to present your case in person or by phone.

Speeding up your sign-up

You can reduce delays by providing medical records yourself rather than waiting for the SSA to request them. If you have seen a doctor in the past three months, ask for copies of recent test results, imaging reports, and clinical notes. Mail them to the SSA with your claim number, or upload them through your my Social Security account if you filed online.

You can also help by being thorough on the initial form. The more detail you provide about your condition, your symptoms, and how they affect your ability to work, the less likely the examiner will need to contact you for clarification. If you have difficulty filling out the form because of your disability, you can ask a family member or advocate to help you, or you can file in person at your local office and ask a representative to information you.

Frequently Asked Questions

Can I sign up for SSDI if I am still working?

Yes. You can work and sign up at the same time. However, if you are earning more than $1,550 per month (in 2024), the SSA may question whether you are truly unable to work. The amount changes each year. If you are working but earning less than this, or if you are working part-time while managing a severe condition, explain this in your claim.

What if I do not have all my doctors' contact information?

Provide the information you have. If you remember the name of a hospital or clinic but not the exact address, the SSA can usually find it. You can also call your health insurance company — they have records of every provider you have seen. If you realize after you sign up that you forgot to list a doctor, call 1-800-772-1213 and ask to add them to your claim.

Do I need a lawyer to sign up?

No. Signing up is free and you can do it yourself. However, if your claim is denied and you appeal, many people find it helpful to work with a disability advocate or lawyer who specializes in SSDI appeals. You only pay them if you win, and the fee is capped by law at 25 percent of your back pay.

What if I sign up and then my condition improves?

Tell the SSA when ready. If you are approved and your condition improves enough that you can work, you can return to work without losing your benefits right away — there is a trial work period that lets you test your ability to work. If you are still in the decision process when your condition improves, the SSA may deny your claim because you no longer meet the definition of disability.

Can I sign up for both SSDI and SSI at the same time?

If you have never worked or do not have enough work history for SSDI, you may be able to sign up for Supplemental Security Income (SSI) instead. The SSA will evaluate you for both programs if you are unsure which one you may have access to for. When you sign up, mention that you want to be considered for both if you think you might may have access to for either one.
