1. Personal Identification and Work History

To start your SSDI application, you’ll need:

• Proof of identity (e.g., driver’s license or state-issued ID)
• Social Security number
• Birth certificate or proof of birth
• Work history for the past 15 years, including job titles, duties, and dates of employment
• Earnings records or W-2s/tax returns for recent years

These documents help the SSA confirm that you meet the non-medical eligibility criteria, such as having sufficient work credits.

2. Detailed Medical Records

This is the most important part of your SSDI application. Required medical documents include:

• Medical diagnoses and clinical notes from doctors
• Lab results, imaging scans, and test results (e.g., MRIs, X-rays)
• Treatment records and prescribed medications
• Statements from treating physicians detailing your limitations
• Hospital discharge summaries and surgery records, if applicable

Make sure these records are recent, comprehensive, and well-organized. The SSA needs clear evidence that your condition is severe and long-lasting enough to prevent work.

3. Adult Disability Report (SSA-3368)

This form details your:

• Medical conditions
• Treatment sources
• Medications
• Work limitations
  It’s submitted along with your application and helps the SSA understand how your condition affects your ability to work.

4. Function Report (SSA-3373)

This form asks how your condition affects your daily activities, such as cooking, cleaning, dressing, or socializing. Be honest and thorough — this is used to evaluate the real-world impact of your disability.

5. Authorization to Disclose Medical Information (SSA-827)

This allows the SSA to request and review your medical records directly from your doctors, hospitals, and clinics. Without this signed form, your application may be delayed or denied.
