The paper process for SSDI is called the SSA-16, and you mail it to your local Social Security office

If you cannot or prefer not to explore online through Social Security's website, you can request the paper form SSA-16 (process for Disability Insurance Benefits) and submit it by mail. You will need to fill it out by hand or type it, gather supporting documents, and send everything to the Social Security office that serves your area. The process takes longer than explore online—typically several weeks just for Social Security to receive and log your process—but the form itself asks the same questions and leads to the same decision.

You can get the SSA-16 by calling Social Security at 1-800-772-1213 (TTY 1-800-325-0778), visiting your local Social Security office in person, or downloading it from ssa.gov. Once you have completed it, you mail the original signed form along with copies of your supporting documents to the address Social Security provides for your region.

Key Takeaways

  • The SSA-16 is the official paper form for SSDI, and you must sign it in front of a witness or have it notarized depending on how you submit it.
  • You will need to gather copies of your birth certificate, proof of citizenship or legal residency, medical records, work history, and tax returns before you mail the form.
  • Mailing your process takes 1 to 3 weeks for Social Security to receive it, plus several more weeks to process and send you a receipt notice.
  • If you make a mistake on the form or forget to include a document, Social Security will contact you by mail to ask for corrections or missing information.
  • You can check the status of your mailed process by calling Social Security or visiting your local office, but you will need your Social Security number and the date you mailed it.

Where to get the SSA-16 form

You have three ways to obtain the paper process. The fastest is to call Social Security's main line at 1-800-772-1213 and ask them to mail you the SSA-16; they will send it within a few business days. You can also visit your local Social Security office in person and ask for the form there—they may give it to you when ready or mail it to you depending on the office's procedures.

The third option is to read and print the SSA-16 directly from ssa.gov. Search for "SSA-16" on the Social Security website, and you will find a PDF you can print at home. If you read it, you can fill it out by hand or print it blank and type on it before signing and mailing it. Whichever method you choose, make sure you are using the current version of the form—Social Security updates it occasionally, and an outdated form may cause delays.

What information and documents you need to include

Before you start filling out the SSA-16, gather copies of the documents Social Security will ask for. You will need your original birth certificate or a certified copy, proof that you are a U.S. citizen or lawful resident (such as a passport, naturalization papers, or a green card), and your Social Security card or a record of your number. Have these ready so you can reference them as you complete the form.

You will also need medical records that show your condition and when it started. These can include doctor's visit notes, hospital discharge summaries, test results, imaging reports, and mental health treatment records. Gather records from the past 12 months if possible, but include older records too if they show how your condition has progressed. If you have not seen a doctor recently, Social Security may ask you to get a medical exam at their expense before they make a decision.

Bring copies of your work history, including the names and addresses of employers you have worked for in the past 15 years, the dates you worked there, and the type of work you did. You will also need your most recent tax returns (usually the past two years) and W-2 forms or 1099 forms showing your earnings. If you are self-employed, bring copies of your business tax returns and profit-and-loss statements.

How to fill out the SSA-16

The SSA-16 has multiple pages and asks for personal information, work history, medical history, and details about your condition and how it affects your ability to work. Start with the top section and fill in your name, date of birth, Social Security number, and contact information exactly as they appear on your Social Security card. Use black or blue ink if you are writing by hand, and print clearly so Social Security can read it.

As you move through the form, answer every question that applies to you. If a question does not explore, write "N/A" rather than leaving it blank—this tells Social Security you read the question and decided it did not fit your situation. For questions about your medical condition, be specific: instead of writing "back pain," write "chronic lower back pain with herniated disc at L4-L5, diagnosed in 2019." The more detail you provide, the clearer your case becomes.

When you reach the signature line at the end, you must sign the form in front of a witness who is not a family member, or have your signature notarized. Some Social Security offices accept a witnessed signature; others require notarization. Call your local office or check the instructions that come with the form to find out which one applies in your area. Without a proper signature, Social Security will return the form and ask you to resubmit it.

Making copies and preparing to mail

Before you mail anything, make a complete copy of the signed SSA-16 and all supporting documents for your own records. Keep these copies in a safe place so you have proof of what you sent if Social Security loses something or if you need to follow up later. Then prepare the originals or certified copies to mail.

For most documents, you can mail photocopies instead of originals—Social Security does not need the original birth certificate or medical records. However, some documents must be originals or certified copies. Check the form's instructions or call Social Security to confirm which documents in your stack need to be originals. If you are mailing certified copies (such as a certified birth certificate), order them from the vital records office in the state or county where you were born or where the event occurred.

Do not mail original documents unless Social Security specifically asks you to. Use a mailing method that allows you to track the package, such as certified mail with return receipt or a carrier service that provides tracking. This way, you will have proof that you mailed the process and when it arrived. Write your Social Security number on the outside of the envelope so Social Security can match the mail to your case if the envelope gets separated from the contents.

Where to send your process

Social Security has regional processing centers, and the address where you mail your process depends on which state you live in. The SSA-16 form or the cover letter that comes with it will include the mailing address for your region. You can also find the correct address by calling 1-800-772-1213 and asking where to send your paper process, or by visiting your local Social Security office and asking them directly.

Mail your completed form and documents to the address Social Security provides. Do not mail it to the national Social Security headquarters or to your local office unless you are specifically told to do so. Using the wrong address will delay your process because it will have to be forwarded, adding weeks to the processing time.

What happens after you mail your process

After Social Security receives your mailed process, it typically takes 2 to 4 weeks for them to log it into their system and send you a receipt notice. This notice confirms that they have your process and provides a case number you can use to check on your status. Keep this notice in a safe place.

Social Security will then review your process and medical records. If they need more information or documents, they will send you a letter asking for what is missing. You will have a important date (usually 10 days) to respond. If you miss the important date, Social Security may deny your process, but you can ask them to reopen it if you have a good reason for the delay.

The total time from mailing your process to receiving a decision is typically 3 to 6 months, though it can take longer if your case is complex or if you need additional medical exams. You can check the status of your process by calling Social Security at 1-800-772-1213 and providing your Social Security number and the date you mailed the form.

Frequently Asked Questions

Can I mail my process to my local Social Security office instead of the regional address?

Some local offices will accept mailed applications, but most prefer you to use the regional processing center address. Call your local office or the main Social Security number to confirm. If you mail to the wrong address, your process will be forwarded, which adds 1 to 2 weeks to processing time.

What if I make a mistake on the form after I have already mailed it?

Call Social Security at 1-800-772-1213 and tell them about the error. They can note it in your file, or they may ask you to mail a corrected page. Do not mail a new complete process unless Social Security tells you to do so, as this can create confusion about which one is official.

Do I need to notarize my signature or just have a witness?

This varies by Social Security office. Check the instructions that come with the SSA-16 or call your local office to find out which method they accept. If the form says notarization is required and you only have a witness signature, Social Security will return the form and ask you to resubmit it with proper notarization.

Can someone else mail the process for me?

Yes, a family member, friend, or representative can mail your process on your behalf. However, you must sign the form yourself (or have it signed by a court-appointed guardian if you are unable to sign). The person mailing it does not need to sign anything unless they are your authorized representative.

How do I know if Social Security received my mailed process?

If you mailed it with tracking (certified mail or a carrier service), you will get a delivery confirmation. Social Security will also send you a receipt notice 2 to 4 weeks after they receive it. If you do not receive a receipt notice within 6 weeks, call 1-800-772-1213 to confirm they have your process.
