When and how to send a paper form instead of explore online

You can request the paper form for SSDI by calling Social Security at 1-800-772-1213 (TTY 1-800-325-0778) and asking them to mail you the process. They will send you the Form SSA-16-F, which is the official SSDI process form. You fill it out by hand or type it, sign it, and mail it back to the address Social Security provides. This route takes longer than explore online — typically four to six weeks just for the form to arrive, then several more weeks for Social Security to receive and process your completed form — but it works if you cannot use a computer, do not have internet access, or prefer to work on paper.

The paper form asks for the same information as the online process: your medical history, work history, doctors' names and addresses, medications, and the date your condition began. You will also need to gather supporting documents to send along with the form, such as medical records, test results, and proof of your Social Security number. Social Security will tell you which documents to include when they send the form.

Key Takeaways

  • Request the paper form by calling Social Security at 1-800-772-1213; they will mail you Form SSA-16-F at no cost.
  • The paper form asks for your medical history, work history, doctor information, and the date your disability began.
  • You must gather and mail supporting documents with the form, including medical records and proof of your Social Security number.
  • Paper applications take significantly longer than online applications because of mailing time and processing delays.
  • You can ask a family member, friend, or representative to help you fill out the form or submit it on your behalf.

What documents to gather before you start

Before you open the form, collect the documents Social Security will ask you to send with it. You will need proof of your Social Security number (your Social Security card, a birth certificate, or a tax return), proof of citizenship or legal residency (a passport or birth certificate), and your state ID or driver's license. Social Security also requires medical evidence: the names, addresses, and phone numbers of every doctor, hospital, or clinic that has treated you for your condition, plus dates of those visits.

Gather any medical records you already have at home — test results, imaging reports, hospital discharge papers, or letters from your doctors describing your condition. You do not have to send originals; copies are fine. If you do not have copies, Social Security can request them directly from your doctors, but this adds weeks to the process. Having the records ready when you mail the form speeds things up considerably.

You will also need information about your work history: the names of employers, the dates you worked for each one, and the type of work you did. If you have not worked in the past 15 years, you can note that on the form. Social Security will verify your work history using their own records, but providing it yourself prevents delays.

How to complete the form itself

When the form arrives, read all the instructions before you start writing. The form is long — typically 8 to 12 pages — and some questions depend on your answers to earlier ones. Use black or blue ink if you are writing by hand, and print clearly. If you make a mistake, cross it out with a single line and write the correction next to it; do not use white-out or erase.

Start with the basic information section: your name, date of birth, Social Security number, and current address. Then move through the medical history section, listing every condition you have and when it started. Be specific about dates — "January 2022" is better than "last year" — because Social Security uses these dates to determine when your disability began. If you cannot remember exact dates, write the month and year you remember, and Social Security will work with that.

In the work history section, list every job you have held in the past 15 years, starting with your most recent job and working backward. Include the employer name, your job title, the dates you worked there, and how much you earned. If you are still working, write your current earnings. Social Security uses this information to determine whether you are working at a level that would disqualify you from SSDI.

When you reach the medical providers section, list every doctor, specialist, hospital, or clinic that has treated you for your condition. Include their full name, address, phone number, and the dates you saw them. If you have seen the same doctor multiple times, you only need to list them once but note the date range of your visits. Social Security will contact these providers to request your medical records.

Signing and mailing the completed form

Once you have filled out every section, sign and date the form. Your signature must match the name you use on your Social Security record. If you cannot sign your name, you can make a mark (an X or a thumbprint) and have a witness sign next to it, stating that you made the mark. The witness must print their name and address.

Make a copy of the completed form and all documents you are sending before you mail anything. Keep this copy for your records. Then place the form and all supporting documents in an envelope and mail it to the address Social Security provided when they sent you the form. Use regular mail or certified mail with return receipt — certified mail costs a few dollars more but gives you proof that Social Security received your process.

Do not send original documents unless Social Security specifically asks you to. Copies are acceptable, and originals can be lost in the mail. If you are mailing medical records, send copies only.

What happens after you mail the form

Social Security typically takes two to three weeks to receive your mailed process, depending on mail delivery times. Once they receive it, they will send you a letter confirming receipt and assigning your process a number. Keep this number; you will use it to check on your process status.

After receipt, Social Security will review your form and request any missing information or documents. If they need something from you, they will mail you a letter asking for it. Respond to these requests as quickly as you can, because delays in sending requested information can slow down your case. If Social Security needs medical records you do not have, they will contact your doctors directly, but this adds time.

The entire process from mailing to a decision typically takes three to six months, though some cases take longer if your medical condition is complex or if Social Security needs additional information. You can check your process status by calling Social Security at 1-800-772-1213 and providing your process number.

Getting help filling out the paper form

You do not have to fill out the form alone. A family member, friend, or representative can help you complete it or can submit it on your behalf. If someone else signs the form for you, they must write "by [your name]" next to their signature and include their name and address. Social Security will still contact you to verify information, so make sure the person helping you has your permission to share your medical and work history.

If you work with a disability representative — such as a lawyer, accredited representative, or non-profit advocate — they can fill out the form with you and handle mailing it. Some representatives charge a fee (up to 25 percent of your back pay if you win), while others work for free. You can find free representatives through your state's Protection and Advocacy for Beneficiaries of Social Security (PABSS) program or through local disability organizations.

Paper process vs. online process: what changes

The main difference between paper and online applications is time. An online process through Social Security's website takes about 15 to 20 minutes to complete and reaches Social Security when ready. A paper process takes weeks to arrive by mail, then weeks more for Social Security to process. If you are explore for SSDI because you cannot work due to a disability, the faster route is usually better because it gets your case in the queue sooner.

The information you provide is identical either way. Social Security asks the same questions, requires the same documents, and makes the same decision. The only reason to choose paper is if you genuinely cannot access the online form — no internet, no computer, or a disability that makes typing difficult. If you have any way to go online, the online process will get you a decision faster.

Frequently Asked Questions

Can I submit the paper form in person at a Social Security office instead of mailing it?

Yes. You can bring the completed form and documents to your local Social Security office and hand it to a representative. Call ahead to confirm office hours and ask if you need an appointment. Submitting in person gives you a receipt showing Social Security received your process that day, which can be useful if you need proof of filing.

What if I do not have all the documents Social Security asks for?

Mail the form with whatever documents you have. Social Security can request missing medical records directly from your doctors and hospitals. Sending an incomplete process is better than delaying to gather everything, because your process date is the date Social Security receives it, not the date you send it.

How do I check on my paper process after I mail it?

Call Social Security at 1-800-772-1213 with your process number (provided in the receipt letter). They can tell you whether they received it, what stage it is in, and whether they need any additional information from you. You can also create a my Social Security account online to check your process status if you have internet access.

Can I switch to an online process if I change my mind after requesting the paper form?

Yes. If the paper form has not arrived yet, call Social Security and ask them to cancel the paper form request. Then you can start an online process at ssa.gov. If the paper form has already arrived, you can still start an online process, but tell Social Security about both so they do not process two separate applications.

What if I make a mistake on the form after I mail it?

Call Social Security at 1-800-772-1213 and tell them about the error. They can note the correction in your file. Do not mail a corrected form unless Social Security asks you to; a phone call is usually enough to fix minor mistakes.
