Step 4: Submitting Your process to Social Security
Step 4 is when you send your completed process to Social Security. You have three routes: mail it to your local Social Security office, walk in with it in person, or file online through Social Security's website. Most people who file online finish faster because Social Security can begin reviewing your case when ready, and you receive a confirmation number on the spot. If you mail or walk in, bring or send the original signed process plus all supporting documents — birth certificate, medical records, work history, and any other evidence you gathered in Steps 1 through 3.
Social Security will send you a receipt notice within two weeks of receiving your process. This notice includes your case number and the name of the claims representative assigned to your case. Keep this number; you will need it for every phone call or letter about your claim. If you do not receive a receipt within three weeks, call your local Social Security office to confirm they have your file.
Key Takeaways
- You can file online at ssa.gov, by mail to your local office, or in person — online is usually fastest because Social Security begins reviewing your case the same day.
- Your process must include your signed SSA-16 form plus all supporting documents you gathered in earlier steps; incomplete applications delay processing.
- Social Security will send you a receipt notice with your case number within two weeks; save this number because you will need it to check on your claim.
- Processing time from Step 4 to a decision typically takes three to six months, though cases involving medical evidence or work history can take longer.
- If Social Security needs more information, they will contact you by mail or phone using the contact details on your process.
Filing Online Through My Social Security
The fastest way to submit is through My Social Security, Social Security's online portal at ssa.gov. You create an account, log in, and complete your process on screen. Social Security saves your work as you go, so you can stop and return later if you need to gather more documents. When you submit, you receive a confirmation number when ready and can upload supporting documents directly into your case file.
Online filing works best if you have already gathered your medical records, work history, and other evidence. If you are missing documents, you can still submit your process and upload them later — Social Security will hold your case and wait for the materials. The system shows you which documents they have received and which are still needed. You can check your case status anytime by logging back into My Social Security.
Mailing or Delivering Your process in Person
If you prefer paper, print the completed SSA-16 form and mail it to your local Social Security office, or walk in during business hours with the original signed form and all supporting documents. Find your local office address at ssa.gov/locator or call 1-800-772-1213. If you mail it, use certified mail with return receipt so you have proof Social Security received it.
In-person filing can be useful if you have questions while filling out the form or if you want to hand over documents directly to a representative. However, walk-in appointments often have long wait times. Many offices now require you to schedule an appointment in advance through their website or by phone. Mailed applications typically arrive within three to five business days, but certified mail adds a few days to the timeline.
What Documents You Must Include
Your process packet must contain the signed SSA-16 form plus originals or certified copies of your birth certificate, Social Security card, and proof of citizenship or legal residency. You also need medical evidence — doctor's reports, hospital records, test results, or mental health evaluations that describe your condition and how it limits your work. If you have not seen a doctor recently, Social Security may order a consultative exam at no cost to you, but submitting existing medical records speeds up the process.
Include your complete work history for the past 15 years, with employer names, dates worked, and job titles. If you are self-employed, bring tax returns for the past two years. Add any other documents that support your claim: letters from doctors, statements from family members about how your condition affects daily life, school records if your disability began in childhood, or military discharge papers if you are a veteran. Social Security will request anything missing, but submitting everything upfront shortens the review time.
What Happens After You Submit
Once Social Security receives your process, a claims representative is assigned to your case. They review your medical evidence, work history, and the details you provided on the SSA-16. If your medical records clearly show you cannot work, the representative may approve your claim within a few weeks. If the evidence is unclear or incomplete, they will contact you by phone or mail asking for more information.
Social Security may also order a consultative examination — a medical exam performed by a doctor they hire — if your medical records are old or do not fully describe your condition. You do not pay for this exam. The doctor sends their report to Social Security, and the claims representative uses it to decide your case. Processing time from submission to a decision is typically three to six months, though cases involving complex medical issues or extensive work history can take longer.
Tracking Your process Status
If you filed online, log into My Social Security anytime to see your case status. The portal shows whether Social Security is reviewing your process, whether they have received all documents, and whether they need anything from you. If you filed by mail or in person, call your local Social Security office or the national line at 1-800-772-1213 with your case number to ask for an update. Have your Social Security number and case number ready when you call.
Social Security will contact you if they need more information. They typically call the phone number on your process first, then send a letter if they cannot reach you by phone. If you move or change your phone number, contact Social Security when ready so they can update your file. Missing a request for information can delay your case or result in a denial, so respond as soon as you receive any contact from them.
What to Do If Your process Is Denied
If Social Security denies your claim, you receive a written decision explaining why. You have the right to appeal — request that Social Security review the decision again. The first level of appeal is called reconsideration, and you must request it within 60 days of the denial letter. You can submit new medical evidence, new work history, or additional statements supporting your claim. Reconsideration is reviewed by a different claims representative who was not involved in the original decision.
If reconsideration is also denied, you can request a hearing before an Administrative Law Judge, then appeal to the Appeals Council, and finally to federal court. Each level allows you to submit new evidence and explain why you believe you are disabled. Many people hire a disability representative or attorney at the hearing stage because the process becomes more formal. You do not pay upfront; representatives are paid only if you win, and only from your back pay.
Frequently Asked Questions
Can I file my SSDI process online if I do not have a computer?
Yes. You can walk into any Social Security office and a representative will help you file online using their computer, or you can file by mail. Call 1-800-772-1213 to schedule an in-person appointment or find your local office at ssa.gov/locator.
What if I do not have all my medical records when I submit?
Submit your process anyway with the records you have. Social Security can request records directly from your doctors and hospitals, or they may order a consultative exam. Submitting early is better than waiting to gather everything, because your claim date starts when Social Security receives your process.
How long does it take to hear back after I submit my process?
You should receive a receipt notice within two to three weeks. A decision on your claim typically takes three to six months, depending on how much medical evidence you submitted and how complex your case is. You can check your status anytime through My Social Security or by calling your local office.
Do I need to hire a representative to submit my process?
No. You can file on your own at no cost. A representative or attorney can help you gather evidence and prepare your case, but many people file successfully without one. If your claim is denied and you appeal, that is when many people choose to hire help.
What if Social Security loses my process?
If you filed online, you have a confirmation number proving submission. If you mailed it, certified mail with return receipt provides proof of delivery. Call Social Security with your confirmation number or receipt number, and they can locate your case. If you cannot find proof, you can resubmit your process — the earliest date you filed counts as your claim date.
