What documents do I need to apply for SSDI?

You need your Social Security number, birth certificate, medical records from all treating sources, names and contact information for all doctors, a detailed work history for the past 15 years, and any award letters from other disability benefits [§ 42 U.S.C. 405]. The more complete your medical records, the stronger your application.

Can I apply for SSDI online?

Yes, you can start your SSDI application online at ssa.gov, by phone at 1-800-772-1213, or in person at an SSA field office in Alabama (locations include Birmingham, Huntsville, Mobile, Montgomery, Tuscaloosa, Dothan, Gadsden, Jasper, Talladega). The online application can be saved and completed over multiple sessions.

How does SSA determine if I am disabled?

SSA uses a five-step sequential evaluation process [§ 20 C.F.R. 404.1520]: (1) Are you working above SGA? (2) Is your condition "severe"? (3) Does your condition meet a listed impairment? (4) Can you do your past work? (5) Can you do any other work? You must be found disabled at one of these steps to qualify.

How far back can I receive SSDI benefits?

SSDI benefits include a mandatory 5-month waiting period from your established onset date [§ 42 U.S.C. 423]. You can receive up to 12 months of retroactive benefits from the date you file your application, meaning your onset date can be up to 17 months before your application date.

What happens after I submit my SSDI application in Alabama?

Your application is forwarded to Alabama Disability Determination Service (DDS), Department of Rehabilitation Services, which reviews your medical evidence and may schedule consultative exams. Processing typically takes 150-210 days. You will receive a written decision by mail.
