You cannot sign up for SSDI online or through a single form—you have to file a claim with Social Security, and the process takes several months from start to decision.
Social Security Disability Insurance (SSDI) requires you to submit a formal claim, not fill out a quick signup. The claim itself is free, but it asks for detailed medical records, work history, and personal information. Social Security then sends your case to a state agency called Disability information Services (DDS), which reviews your medical evidence and decides whether your condition meets their definition of disability. The whole process typically takes three to six months, though some cases take longer.
You have three ways to file: in person at your local Social Security office, by phone, or by starting online and finishing in person or by phone. Each route takes the same amount of time and leads to the same decision process. The choice depends on what works for your schedule and whether you need help filling out forms.
Key Takeaways
- You file a claim with Social Security, not a separate SSDI program, and the claim itself is free.
- Social Security sends your medical records to your state's Disability information Services, which makes the approval or denial decision.
- The process takes three to six months on average, and you can file in person, by phone, or start online and complete it by phone.
- You will need your Social Security number, birth certificate, medical records from the past 12 months, and a list of jobs you have held in the past 15 years.
- If Social Security denies your claim, you can request reconsideration within 60 days, and most people who appeal eventually receive benefits.
What Documents You Need Before You File
Gather these documents before you contact Social Security. You will need your Social Security number, birth certificate, and proof of citizenship or legal residency (a passport, green card, or naturalization papers). Have your driver's license or state ID ready as well.
Bring a list of all doctors, hospitals, and mental health providers who have treated you in the past 12 months, including their names, addresses, and phone numbers. If you have recent test results, imaging reports, or hospital discharge papers, collect those too. Social Security will request your full medical records from these providers, but having the contact information ready speeds up the process.
Write down every job you have held in the past 15 years, including the job title, employer name, dates you worked there, and what your duties were. Include self-employment or informal work. Social Security uses this to calculate how much you earned and whether you meet the work history requirement for SSDI.
Filing in Person at Your Local Social Security Office
Call 1-800-772-1213 to find the Social Security office nearest you and schedule an appointment. You can also search online at ssa.gov and use the office locator tool. Appointments are free and usually available within one to three weeks. Bring all the documents listed above, plus your original birth certificate and proof of citizenship.
At your appointment, a Social Security representative will ask you questions about your medical condition, when it started, how it affects your ability to work, and your work history. They will fill out the process form (called the Adult Disability Report) as you answer. The appointment usually takes 30 to 45 minutes. You will receive a receipt showing your claim number and the date you filed.
After your appointment, Social Security sends your claim to your state's Disability information Services. You do not need to do anything else at this stage—DDS will request your medical records directly from your doctors and hospitals. You can check the status of your claim online at ssa.gov using your claim number, or by calling 1-800-772-1213.
Filing by Phone
Call 1-800-772-1213 to file over the phone. You can reach Social Security Monday through Friday, 7 a.m. to 7 p.m. Eastern time. Have all your documents ready before you call, because the representative will ask the same questions they would ask in person. The call usually takes 30 to 45 minutes.
After the call, Social Security will mail you a receipt with your claim number and filing date. Keep this receipt—you will need the claim number to check your status or contact Social Security later. Your claim then goes to Disability information Services, just as it would if you filed in person.
Starting Your Claim Online and Finishing by Phone
You can begin your SSDI claim on ssa.gov by creating a my Social Security account and starting the online process. The online form lets you enter your basic information, medical history, and work history at your own pace. You do not have to finish it all at once—you can save your progress and return later.
After you submit the online form, Social Security will contact you by phone to finish the process and answer any questions. This route works well if you want time to gather your information or prefer not to sit through a long phone call all at once. The timeline is the same as filing in person or by phone: your claim goes to Disability information Services after Social Security receives your completed process.
What Happens After You File
Once your claim is filed, Disability information Services takes over. They request your medical records from every doctor, hospital, and therapist you listed. This usually takes two to four weeks. If your records are incomplete or if DDS needs more information, they may contact you or your doctors directly.
DDS reviews your medical evidence against Social Security's definition of disability: a condition that prevents you from doing substantial work and is expected to last at least 12 months or result in death. They also check whether you meet the work history and earnings requirements for SSDI. If they approve your claim, they calculate your monthly benefit amount based on your earnings record.
You will receive a written decision in the mail. If approved, your first check arrives within one to two months. If denied, the letter explains why and tells you how to request reconsideration within 60 days. Most people who are denied the first time are approved on reconsideration or at a hearing before an administrative law judge.
Timeline From Filing to First Payment
| Stage | What Happens | Typical Time |
| Filing your claim | You meet with Social Security in person, by phone, or online to submit your process. | Same day or within 1–3 weeks of scheduling |
| Records collection | Disability information Services requests your medical records from your providers. | 2–4 weeks |
| Medical review | DDS reviews your records and checks your work history and earnings. | 4–8 weeks |
| Decision letter | You receive approval or denial in the mail. | 3–6 months from filing |
| First payment (if approved) | Your first check arrives by direct deposit or mail. | 1–2 months after approval |
If Your Claim Is Denied
A denial does not mean you cannot receive SSDI. You have the right to request reconsideration within 60 days of the denial letter. In reconsideration, a different examiner at DDS reviews your case and any new medical evidence you have gathered. About one-third of people who are denied are approved on reconsideration.
If reconsideration is also denied, you can request a hearing before an administrative law judge. A judge reviews your entire case and can hear testimony from you and medical experts. Many people are approved at the hearing stage. You can represent yourself or hire a disability lawyer to help you. Lawyers are paid only if you win, and their fee is capped by Social Security at 25 percent of your back pay.
Frequently Asked Questions
Can I file for SSDI if I am still working?
Yes. You can work and file for SSDI at the same time. Social Security looks at whether your condition prevents you from doing substantial work, not whether you are currently working. If you are working but earning less than $1,550 per month (as of 2024), you may still may have access to. The earnings limit changes each year, so ask Social Security about the current amount when you file.
Do I need a lawyer to file for SSDI?
No. You can file on your own without a lawyer. However, if your claim is denied and you appeal, a lawyer can help you gather medical evidence and prepare for a hearing. You only pay the lawyer if you win, and the fee comes from your back pay, not from your pocket.
What if I do not have recent medical records?
Tell Social Security when you file. If you have not seen a doctor in several months, Social Security may ask you to see one so they have current medical evidence. In some cases, they will pay for an exam. Having any medical records is better than having none, so file even if your records are incomplete.
How much will my SSDI check be?
Your monthly benefit is based on your lifetime earnings record, not on your medical condition or how disabled you are. The average SSDI payment in 2024 is around $1,550 per month, but yours could be higher or lower depending on how much you earned while working. Social Security will tell you the exact amount in your approval letter.
Can I work while receiving SSDI?
Yes, but there are limits. You can earn up to $1,550 per month (as of 2024) without losing your benefits. Above that amount, Social Security reduces your check by $1 for every $2 you earn. After nine months of work above the limit, your benefits stop. This is called the trial work period, and it gives you a chance to test whether you can work without when ready losing your income.
