# Overview

The Social Security Administration administers two federal programs commonly discussed when people say "disability benefits": Social Security Disability Insurance and Supplemental Security Income.

# SSDI

Social Security Disability Insurance, commonly shortened to SSDI, is generally connected to a person's insured status and work record under Social Security. Other requirements also apply.

# SSI

Supplemental Security Income, commonly shortened to SSI, is a needs-based program with financial and other requirements. Work credits are not the central eligibility basis in the same way they are for SSDI.

# Important Limitation

The readiness screening may collect information that can help a person prepare, but it does not decide whether SSDI, SSI, both programs, or neither program applies. Only the Social Security Administration can make the official determination.

Program rules and financial thresholds can change. Current figures should be confirmed through official SSA sources rather than inferred from this bundle.
