What form you need and where to get it

The form you need is called Form SSA-16-F, officially titled "process for Disability Insurance Benefits." This is the only form Social Security uses to start an SSDI claim. You do not fill out different forms depending on your condition or age—everyone uses SSA-16-F.

You can get a printable copy directly from the Social Security Administration website at ssa.gov. Search for "SSA-16-F" and you will find a PDF you can read and print at home. The form is also available at your local Social Security office, and you can call 1-800-772-1213 to request a printed copy by mail.

The form itself is 8 pages long and includes sections for your personal information, work history, medical conditions, and details about any treatment you have received. You will also need to gather supporting documents before you start filling it out—having these ready makes the process faster and reduces the chance that Social Security will ask you to resubmit information later.

Key Takeaways

  • Form SSA-16-F is the only process form Social Security uses for SSDI claims, and you can read it free from ssa.gov or request it by phone or in person.
  • Gather your medical records, work history, and proof of citizenship or legal residency before you start filling out the form to avoid delays.
  • You can submit a printed form by mail, drop it off in person at a Social Security office, or file online through your Social Security account without printing anything.
  • If you mail the form, keep a copy for your records and consider using certified mail so you have proof Social Security received it.
  • Social Security will contact you within a few days of receiving your process to schedule a telephone interview and ask follow-up questions.

Documents to gather before you print and fill out the form

Social Security will ask for specific documents when you submit your process. Having these ready before you start filling out SSA-16-F means you can submit everything at once instead of mailing it in pieces.

You will need proof of citizenship or legal residency—a birth certificate, passport, or permanent resident card. You will also need your Social Security number and a photo ID. For your work history, gather your last W-2 form or tax return, or a list of employers, job titles, and dates you worked for each one going back 15 years. Social Security uses this to calculate your benefit amount if you are found to have a disability.

For your medical history, collect the names and addresses of all doctors, hospitals, and mental health providers who have treated you for your condition. Include dates of treatment and the type of care you received. If you have recent test results, imaging reports, or medical records, include those too. Social Security will request your full medical file from your providers, but submitting what you have speeds up the process.

How to fill out the form step by step

Start with Section 1, which asks for your name, date of birth, Social Security number, and contact information. Use your legal name as it appears on your Social Security card. If you have changed your name, include your former name in the space provided.

Section 2 asks about your citizenship and residency. Answer honestly about whether you are a U.S. citizen, lawful permanent resident, or other immigration status. Social Security will verify this with immigration records, so any mismatch will delay your case.

Section 3 covers your work history. List every job you have held in the past 15 years, including the employer name, your job title, the dates you worked, and how much you earned. If you are still working, include your current job and your current monthly earnings. This section is important because Social Security uses it to determine whether you are engaging in substantial gainful activity—work that earns above a certain threshold (in 2024, $1,550 per month for non-blind individuals). If you earn more than this amount, Social Security will likely deny your claim.

Section 4 asks you to describe your medical condition and how it limits your ability to work. Be specific: instead of writing "back pain," write "severe lower back pain from a herniated disc that prevents me from standing for more than 30 minutes." Describe what you cannot do, not just what you have. This section does not require medical jargon—plain language is fine and often clearer.

Submitting your completed form

Once you have filled out SSA-16-F and gathered your supporting documents, you have three ways to submit your process.

By mail: Send the completed form and copies of your documents to your local Social Security office. You can find the address on ssa.gov or by calling 1-800-772-1213. Make a copy of everything for your records before you mail it. Using certified mail with return receipt gives you proof that Social Security received your process, which is useful if there is ever a dispute about when you filed.

In person: Walk into your local Social Security office with the completed form and documents. A representative will review what you brought, make sure nothing is missing, and give you a receipt showing the date you filed. This is the fastest way to confirm your process was received.

Online: If you have a my Social Security account, you can file your process through the website without printing the form. Log in, select "explore for Retirement, Family, or Disability Benefits," and follow the prompts. You will still need to upload or mail supporting documents, but the form itself is completed digitally.

What happens after you submit the form

Social Security will send you a notice confirming receipt of your process within a few days. This notice includes a claim number—save this number because you will use it to check the status of your case and to contact Social Security about your claim.

Within one to two weeks, a Social Security representative will call you to conduct a telephone interview. They will ask detailed questions about your medical history, your work, your daily activities, and how your condition affects you. Answer these questions as thoroughly as you can. This interview is recorded and becomes part of your official file.

After the interview, Social Security will request your complete medical records from every doctor and hospital you listed on the form. This process usually takes four to six weeks. Once Social Security has your records, a medical consultant employed by the state disability agency will review them and write a medical assessment. This assessment is sent to a disability examiner at Social Security, who makes the initial decision on your case.

You will receive a written decision in the mail. If you are found to have a disability, the notice will include your benefit amount and your first payment date. If you are denied, the notice will explain why and tell you how to request reconsideration within 60 days.

Common mistakes to avoid when filling out the form

Do not leave sections blank. If a question does not explore to you, write "N/A" so Social Security knows you saw the question and chose not to answer it. Blank spaces can cause Social Security to contact you asking for clarification, which delays your case.

Do not understate your limitations. Social Security reviewers read thousands of applications. Vague descriptions like "I cannot work" do not help your case. Instead, describe specific activities you cannot do: "I cannot lift more than 10 pounds," "I cannot sit for longer than one hour without severe pain," "I cannot concentrate for more than 15 minutes at a time." The more specific you are, the easier it is for the medical consultant to match your description to the medical evidence in your file.

Do not list only recent treatment. If you have been seeing a doctor for five years but only mention the last six months of visits, Social Security will think your condition is new. List all relevant treatment, even if it was years ago. Social Security wants to see the full history of your condition.

Do not submit original documents. Always submit copies. Original birth certificates, passports, and medical records can be lost in the mail or in Social Security's files. Keep the originals and send photocopies.

Frequently Asked Questions

Can I print the form and fill it out by hand, or do I have to type it?

You can do either. The PDF form accepts typed input if you open it on a computer, but you can also print it and fill it out by hand with a pen. If you write by hand, use black or blue ink and write clearly so Social Security can read your answers. Handwritten applications are processed the same way as typed ones.

What if I do not have all my medical records when I submit the form?

Submit the form with the information you have. On the form, list the names and addresses of all your doctors and hospitals, and Social Security will request your records directly from them. You do not need to collect and mail the records yourself. However, the sooner Social Security has your complete medical file, the sooner they can make a decision.

Do I need to notarize the form or have it witnessed?

No. You do not need a notary or witness. straightforward sign and date the form where it asks for your signature. Social Security does not require notarization for SSDI applications.

How long does it take Social Security to process the form after I submit it?

Initial processing takes three to five months on average, though some cases take longer depending on how complex your medical history is and how busy your local office is. You can check the status of your process anytime by logging into your my Social Security account or by calling 1-800-772-1213 with your claim number.

Can I submit the form online instead of printing it?

Yes. If you have a my Social Security account, you can file your entire process online without printing anything. The online version asks the same questions as the paper form. You will still need to upload or mail copies of your supporting documents, but the process itself is completed digitally.
