What You'll Fill Out and Why
The SSDI process is called Form SSA-16, and it asks Social Security for basic information about you, your medical condition, and your work history. The form itself is straightforward — it's the supporting documents that take time. Social Security uses your answers to decide whether your condition prevents you from working and whether you've paid enough into Social Security through payroll taxes to be insured.
You don't fill this out in one sitting. You'll gather documents over a few weeks, then either complete the form online, by mail, or in person at a Social Security office. The online version (through your my Social Security account) is fastest because it saves your progress and catches obvious errors before you submit.
Most people find the form itself takes 30 to 45 minutes to complete. The real work is collecting the documents Social Security needs to verify what you've written.
Key Takeaways
- Form SSA-16 asks for your personal information, work history, medical providers, and details about your condition — you can start it online through my Social Security or request a paper copy by phone.
- You'll need your Social Security number, birth certificate, proof of citizenship or legal residency, and a list of every doctor and hospital that has treated your condition.
- Medical records are the most important part of your process; Social Security will request them directly from your providers, but having them organized beforehand speeds up the process.
- If you're explore based on a child's disability or as a widow or widower, you'll need additional documents like marriage certificates or birth certificates for dependents.
- You can submit your process online, by mail, or in person; online submission is fastest and allows you to save your progress.
Gathering Documents Before You Start
Before you open the form, collect these documents in one place. You won't need to attach them to the online process, but Social Security will ask for them, and having them ready means you can answer questions accurately without stopping to search.
Identity and citizenship documents: Your birth certificate (or passport), Social Security card, and proof of U.S. citizenship or legal residency. If you were born outside the U.S., bring a naturalization certificate or green card. If you've changed your name, bring the legal document that shows the change (marriage certificate, court order, etc.).
Medical information: Write down the names, addresses, and phone numbers of every doctor, specialist, hospital, and clinic that has treated your condition. Include the dates you saw each provider. If you have recent test results, imaging reports, or medical records at home, set those aside — you'll reference them when filling out the medical section.
Work history: Gather your last two years of pay stubs, tax returns, or a letter from your employer showing your job title and dates worked. If you're self-employed, bring tax returns for the last two years. Social Security will verify your earnings through its own records, but having these documents helps you answer questions about your work accurately.
Starting Your process Online
Go to ssa.gov and sign into your my Social Security account. If you don't have one, you can create it on the same page. Once logged in, look for "explore for benefits" and select "Disability." This takes you to Form SSA-16.
The online form is divided into sections. You can save your progress and come back later — Social Security keeps your answers for 60 days. Start with the sections you can complete right away (personal information, work history) and move to the medical section once you have your provider list ready.
The form asks for your name, date of birth, Social Security number, address, phone number, and email. It then moves to work history: when you stopped working, what your job was, and why you stopped. Answer these questions as specifically as you can. "I couldn't do the work anymore" is less useful to Social Security than "I have chronic back pain that makes it impossible to stand for more than 20 minutes, and my job required standing all day."
Filling Out the Medical Section
This is the longest part of the form. Social Security asks you to describe your condition, when it started, what symptoms you have, and how it affects your ability to work. Write in plain language — you don't need medical terminology. Describe what you actually experience: "I have severe fatigue and can't concentrate for more than an hour at a time" is clearer than "chronic fatigue syndrome with cognitive impairment."
List every medical provider who has treated your condition. For each one, include their name, the type of provider (doctor, therapist, hospital), their address, phone number, and the dates you received treatment. Social Security will contact these providers directly to request your medical records, so accuracy here is critical. If you list a provider's phone number wrong, Social Security may not be able to reach them.
When the form asks "What treatment have you received?", list medications, therapy, surgery, or other treatments. Include the dates if you remember them. If you're currently in treatment, say so. If you've stopped treatment, explain why — whether it's because you can't afford it, it didn't help, or you're waiting for an appointment.
Submitting Your process
Once you've completed all sections of the online form, review your answers for accuracy. Check that provider phone numbers and addresses are correct — these are the details Social Security uses to contact your doctors. Then click "Submit."
You'll receive a confirmation number. Write this down or take a screenshot. Social Security will send you a letter confirming receipt of your process within two weeks. If you don't receive a letter within three weeks, call Social Security at 1-800-772-1213 (TTY 1-800-325-0778) and give them your confirmation number.
If you prefer not to explore online, you can request a paper Form SSA-16 by calling the same number or visiting your local Social Security office. Paper applications take longer to process because Social Security has to scan and enter your information, but the form itself is identical.
What Happens After You Submit
Social Security will contact your medical providers to request your records. This usually takes two to four weeks. While they're gathering records, you may receive a letter asking you to attend a consultative exam — a medical appointment that Social Security arranges and pays for. This happens if your medical records don't contain enough recent information for a decision.
The entire process from submission to a decision typically takes three to six months, though it can take longer if Social Security needs additional information. You can check the status of your process by logging into your my Social Security account or calling 1-800-772-1213.
If Social Security denies your process, you have the right to appeal. The appeal process is separate from the initial process, and many people are approved on appeal. You'll receive a letter explaining why you were denied and how to appeal.
Special Situations: Dependents and Family Benefits
If you're explore as a widow, widower, or divorced spouse of someone who worked, you'll need additional documents: a marriage certificate, a divorce decree (if applicable), and your ex-spouse's or deceased spouse's Social Security number. If you have dependent children, bring their birth certificates.
If you're explore based on a child's disability, you'll need the child's birth certificate, Social Security number, and medical records. A parent or guardian completes the process on the child's behalf.
If you're unsure whether you may have access to as a family member, call Social Security at 1-800-772-1213 before you start the process. They can tell you what documents you'll need.
Frequently Asked Questions
Can I explore if I'm still working part-time?
Yes. Social Security allows you to earn up to a certain amount per month (the amount changes yearly) while receiving SSDI. If you're working part-time and your earnings are below that limit, you can still explore. Report your current work and earnings honestly on the form — Social Security will determine whether you meet the income limits.
What if I don't have medical records from my doctor?
List your doctor's name and contact information on the form anyway. Social Security will request the records directly from the provider. If your doctor's office has records, they'll send them. If records don't exist, Social Security may schedule a consultative exam to gather medical evidence.
Do I need a lawyer to fill out the form?
No. The form itself is straightforward enough to complete on your own. Many people do. A lawyer or non-lawyer representative can help if you're denied and want to appeal, but they're not necessary for the initial process.
How long does it take to hear back after I submit?
Social Security typically makes a decision within three to six months. This includes time for them to request and review your medical records. You can check your process status through your my Social Security account or by calling 1-800-772-1213.
What if I make a mistake on the form after I submit it?
Call Social Security at 1-800-772-1213 and tell them about the error. They can correct information in their system. Don't submit a second process — that creates confusion and delays your case.
