What SSDI Forms Are and Why You Need One

An SSDI form is the official document Social Security uses to collect information about your disability, work history, and medical condition. There is no single "SSDI form"—instead, Social Security sends you specific forms based on your situation. The main form most people start with is the SSA-3368, called the "Disability Report." Other forms arrive later if Social Security needs more details about your medical treatment, work history, or living situation.

You do not fill out forms and mail them in to start the process. Instead, you file a claim in person at your local Social Security office, by phone, or online through Social Security's website. Social Security then sends you the forms they need you to complete. This matters because many people waste time hunting for forms that Social Security will send automatically once your claim is filed.

The forms ask straightforward questions, but they are long and detailed. Social Security uses your answers to decide whether your condition prevents you from working. The more complete and accurate your answers, the faster the process moves.

Key Takeaways

  • Social Security sends you forms after you file a claim—you do not need to find and submit them first.
  • The SSA-3368 (Disability Report) is the main form most applicants receive, asking about your medical condition, treatment, and work history.
  • Additional forms arrive if Social Security needs details about your medical providers, work you did before your disability, or where you live.
  • Forms must be returned within the important date Social Security gives you, usually 10 days, or your claim may be delayed.
  • You can request forms by mail, phone, or online—ask Social Security which method is fastest for your situation.

The Main Form: SSA-3368 Disability Report

The SSA-3368 is the form you will almost certainly receive. It asks you to describe your disability in your own words, list all doctors and hospitals that have treated you, explain what work you did before you became disabled, and detail how your condition affects your daily activities. The form is typically 4 to 6 pages and takes 30 to 60 minutes to complete carefully.

The form asks specific questions like "What is your main condition?" and "When did it start?" It also asks you to list every medical provider you have seen in the past year, including their names, addresses, and phone numbers. Social Security uses this list to request your medical records directly from those providers. If you leave out a provider, Social Security may not see important evidence of your disability.

The form also asks about your work history—what jobs you held, when you worked, and how much you earned. This section helps Social Security understand whether you have worked recently and whether your condition prevents you from returning to that work or any other work.

Other Forms You May Receive

After you return the SSA-3368, Social Security may send additional forms depending on what you reported. The SSA-3373 (Authorization to Disclose Information) is common—it gives Social Security permission to contact your doctors and get your medical records. You must sign and return this form, or Social Security cannot access your medical evidence.

If you worked in the past five years, you may receive the SSA-3369 (Work History Report), which asks for more detail about each job: the type of work, hours per week, physical demands, and how much you earned. This form helps Social Security understand whether your condition prevents you from doing that specific work.

If you receive treatment from a mental health provider, Social Security may send the SSA-3380 (Psychiatric Review Technique Form) or ask your provider to complete it directly. This form documents your psychiatric symptoms and how they affect your ability to function. You do not fill this out yourself—your provider does—but Social Security may ask you to sign a release so they can request it.

If you live with someone else or receive financial support from someone, Social Security may send questions about your living arrangement. This is routine and does not affect your claim; Social Security just needs to know whether you are paying your own expenses.

When Forms Arrive and How Long You Have

Social Security typically mails forms within 5 to 10 days after you file your claim. The envelope will include a important date—usually 10 days from the date on the letter—to return the forms. This important date is firm. If you miss it, Social Security may close your claim and you will have to file again.

If you cannot meet the important date, call Social Security when ready at 1-800-772-1213 and ask for an extension. Social Security can grant extensions, usually for 10 to 30 additional days, but you must request it before the original important date passes. Do not assume an extension will be granted—ask as soon as you know you need more time.

You can return forms by mail, in person at your local Social Security office, or online if you created a my Social Security account. Returning them in person or online is faster because you get confirmation when ready. If you mail them, keep a copy for your records and consider using certified mail so you have proof of delivery.

What Information to Gather Before Filling Out Forms

Before you sit down to complete the SSA-3368, gather these documents: a list of all doctors, hospitals, and mental health providers you have seen in the past year, including their phone numbers and addresses; dates of all medical visits and treatments; a summary of your work history for the past 15 years, including job titles, employers, and dates; and any medical records you already have, such as test results or hospital discharge summaries.

You do not need to have all your medical records before you fill out the form. Social Security will request them from your providers using the information you provide. However, if you already have copies of important records—such as an MRI result, surgery report, or recent doctor's note—include them with your form. This speeds up the process because Social Security does not have to wait for providers to respond.

If you cannot remember exact dates, write down what you do remember. For example, if you do not know the exact date you saw a doctor, write "sometime in March 2023" or "about six months ago." Social Security will contact the provider to confirm the date. Approximate information is better than leaving the field blank.

Common Mistakes When Completing Forms

The most common mistake is leaving fields blank or writing "see attached" without actually attaching anything. Social Security interprets blank fields as "this does not explore to me," which can hurt your claim. If a question does not explore, write "N/A" or "not applicable" so Social Security knows you read the question and considered it.

Another mistake is being vague about your condition or how it affects you. Do not write "I have back pain." Instead, write "I have chronic lower back pain from a herniated disc. I cannot sit for more than 30 minutes without severe pain, and I cannot lift anything heavier than 10 pounds." Specific details help Social Security understand the severity of your condition.

A third mistake is forgetting to list a medical provider. If you saw a doctor even once in the past year, include them. Social Security uses these records to build a complete picture of your condition. Missing a provider means missing evidence that could support your claim.

Finally, do not sign the form without reading it. Make sure all the information is accurate before you sign. If you make a mistake, cross it out, write the correction, and initial the change. Do not use white-out or tape.

How to Request Forms if You Do Not Receive Them

If you filed a claim but did not receive forms within two weeks, contact Social Security at 1-800-772-1213 or visit your local office. Have your Social Security number ready. Ask Social Security to confirm that your claim was filed and to send you the forms you need.

You can also create a my Social Security account at ssa.gov and check the status of your claim. The account will show you which forms Social Security has sent and which ones they are still waiting for. If a form is listed as "pending," it means Social Security sent it and is waiting for you to return it.

If you need a form in a language other than English, Social Security can provide it. Call 1-800-772-1213 and tell them which language you need. Social Security also offers interpreters at local offices if you prefer to complete forms in person with help.

Frequently Asked Questions

Can I fill out forms online or do I have to print and mail them?

If you have a my Social Security account, you can upload completed forms directly through your account. Otherwise, you can print the forms, fill them out by hand or on a computer, and mail them back or bring them to your local Social Security office. Uploading through your account is fastest because Social Security receives them when ready.

What happens if I make a mistake on a form after I submit it?

Call Social Security at 1-800-772-1213 and tell them about the mistake. They can send you a corrected form or allow you to provide the correct information over the phone. Do not assume Social Security will ignore the mistake—correct it as soon as you notice it.

Do I need to provide medical records with my forms or does Social Security get them?

Social Security will request records from the providers you list on the SSA-3368. However, if you already have copies of important records, include them with your form to speed up the process. Do not wait for Social Security to request them if you have them available.

What if I do not remember all my doctors' phone numbers and addresses?

Write down the information you do remember—the doctor's name and the city where they practice. Social Security can locate the office using that information. If you are unsure, call your insurance company; they have a record of all providers you have seen.

Can someone help me fill out the forms?

Yes. A family member, friend, or disability advocate can help you complete forms. If someone other than you signs the form, they must also print their name and relationship to you. You must still sign the form yourself to confirm the information is accurate.
