How to Apply for SSDI Online at SSA.gov
TL;DR: Go to ssa.gov/applyfordisability and create a my Social Security account if you don't have one. The online application covers Form SSA-16-BK and links to the Disability Report (SSA-3368). You can save and return for up to 6 months. The process takes 1 to 2 hours if you have your documents ready. Submit medical releases (SSA-827) and the Function Report (SSA-3373) when the SSA contacts you after filing.
The online SSDI application is the fastest and most flexible way to file your claim. You work at your own pace, review your answers before submitting, and avoid the wait times of phone and in-person appointments. Here is exactly what each section asks and how to handle it.
Before You Start: What You Need
Have these ready before you open the application. Stopping to hunt for information mid-application leads to rushed, incomplete answers.
| Item | Where to Find It |
|---|---|
| Social Security number | Your SS card or tax documents |
| Date and place of birth | Birth certificate |
| Name, address, phone of all treating doctors | Insurance statements, appointment records |
| Dates of all medical visits (approximate is okay) | Patient portals, appointment reminders |
| Names and dosages of all medications | Pharmacy printout or pill bottles |
| Work history for last 15 years | Old resumes, W-2s, LinkedIn |
| Date you became unable to work | Last day worked or last day you could have worked |
| Bank account info for direct deposit | Your bank statement or checkbook |
Creating Your my Social Security Account
If you do not already have a my Social Security account, go to ssa.gov/myaccount. You will need to verify your identity using personal information and either a cell phone number or an existing account with one of SSA's identity verification partners (ID.me or Login.gov).
If you have trouble verifying online, you can visit your local SSA office with a photo ID to complete identity proofing in person.
Starting the Application
Navigate to ssa.gov/applyfordisability and click "Apply for Disability Benefits." The system will ask whether you are applying for yourself or someone else, and whether you want to apply for SSDI, SSI, or both.
For online filing, select SSDI only. SSI requires a phone or in-person interview and cannot be completed fully online. If you may qualify for both, the SSA will screen you for SSI during their follow-up contact.
Section-by-Section Walkthrough
Section 1: Claimant Information
Basic personal details: name, SSN, date of birth, contact info. If you have changed your name (marriage, divorce, legal name change), list all previous names. The SSA needs them to find your complete earnings record.
Section 2: Contact Information
Your address, phone number, and email. Also provide the name and contact information of someone who can reach you if the SSA cannot. This person is not your representative; they are just a backup contact.
Section 3: Disability Information
This section asks for your alleged onset date (AOD), the date you claim you became unable to work because of your condition. This date is extremely important because it determines:
- When your five-month waiting period begins
- How far back your back pay goes (up to 12 months before application)
- Whether your Date Last Insured covers your disability period
Choose the onset date carefully. If you stopped working on March 15 because of your condition, your onset date is March 15. If you stopped working for a layoff but were also disabled, talk to the SSA about the right date to use.
Section 4: Medical Conditions
List every medical condition that limits your ability to work. The online form gives you space for multiple conditions. Use medical terminology when you know it, but plain English is fine. Write "degenerative disc disease L4-L5 with radiculopathy" if you know the diagnosis, or "herniated disc in lower back with leg pain" if you don't.
List conditions in order of severity. Your primary disabling condition should be first.
Section 5: Medical Providers
For each doctor, hospital, or clinic, you will enter:
- Provider name and specialty
- Address and phone number
- First and last dates of treatment
- Conditions treated
- Patient ID or medical record number (if you have it)
List every provider, even if you only went once. Emergency room visits count. Include mental health providers, physical therapists, and chiropractors. Missing a provider means the SSA might never see that evidence.
Section 6: Medications
For each medication, list:
- Name (brand or generic)
- Dosage and frequency
- Prescribing doctor
- Side effects you experience
Side effects matter. If your pain medication causes drowsiness that prevents concentration, or if your antidepressant causes fatigue, document it here. Side effects are legitimate functional limitations.
Section 7: Work History
The online application collects basic work history. The detailed Work History Report (SSA-3369) comes later. For now, list each job in the last 15 years with approximate dates, job title, and basic duties.
Section 8: Education
Your highest level of education and any specialized training. This matters because the SSA considers whether you can be retrained for other work. Lower education levels combined with physical limitations can work in your favor under the grid rules.
Section 9: Payment Information
Set up direct deposit for your benefits. You will need your bank's routing number and your account number. If you prefer not to provide this now, you can set it up later, but direct deposit speeds up your first payment if approved.
Saving and Returning
The online application lets you save your progress at any point. You have six months to return and complete it. The system assigns a re-entry number. Write it down or save the confirmation email. You will also need your Social Security number and the original confirmation number to return.
Do not let the six months expire. If it does, you have to start over and your protective filing date is lost.
After You Submit
Submitting the online application is not the end of the process. Within 2 to 4 weeks, the SSA will contact you to complete additional forms:
- SSA-3373 (Function Report): Detailed description of your daily activities and limitations. See our Function Report guide.
- SSA-3369 (Work History Report): Detailed description of each past job. See our Work History Report guide.
- SSA-827 (Medical Release): Authorization for SSA to collect your medical records.
Return these forms quickly. The SSA gives you 10 to 30 days to respond. Delays in returning forms slow your entire claim and can look like you are not taking the process seriously.
Tips for a Stronger Online Application
| Tip | Why It Matters |
|---|---|
| Draft answers in a separate document first | Lets you review and edit before entering into the system |
| Use the save feature after every section | Prevents losing work if your session times out |
| Print or screenshot every page before submitting | You cannot access the application after submission |
| List conditions using medical terms when possible | Matches Blue Book listing language |
| Include side effects for every medication | Side effects count as additional functional limitations |
| Do not rush the onset date | Wrong date can cost months of back pay |
Common Online Application Issues
Session Timeout
The SSA website times out after 25 to 30 minutes of inactivity. Save frequently. If you are drafting a long answer, write it in a text editor and paste it in.
Character Limits
Some text fields have character limits. If your answer does not fit, focus on the most important details and note that you will provide additional information in the follow-up forms.
Technical Errors
If you get an error message or the site goes down, try again during off-peak hours (early morning or late evening). If the problem persists, call 1-800-772-1213 to report the issue. Your saved progress should still be available.
