Filing an SSDI application without the right documents can cause significant delays — sometimes months. SSA will request missing information, and each back-and-forth adds time to an already slow process. Gathering everything before you start puts you in a much stronger position.
Personal and Identity Documents
- Social Security card or proof of your Social Security number
- Birth certificate or proof of age
- Proof of U.S. citizenship or lawful alien status (if applicable)
- Military discharge papers (Form DD-214) if you served in the military
- Most recent W-2 forms or self-employment tax returns
Medical Records and Treatment History
This is the most important category. SSA needs to see objective medical evidence of your condition.
- Names, addresses, and phone numbers of all doctors, hospitals, and clinics that have treated you
- Names of all medications you currently take and their dosages
- Names and results of any medical tests (MRIs, X-rays, lab work)
- Medical records you already have — especially recent ones
Work History
- Names and addresses of employers for the past 15 years
- Job titles and a brief description of your duties
- Dates of employment
- Information about any workers' compensation or other disability payments you receive
A Note on Medical Records
You do not need to gather every record yourself before applying. SSA will request records from your providers after you apply. However, having recent records — especially from the past 12 months — ready to submit can speed up the process significantly. If you have records showing your diagnosis, treatment history, and functional limitations, include them.
