SSDI vs. SSI

SSDI depends on your work record. SSI depends on limited income and resources. SSA runs both programs, and for adults the medical standard is generally the same in both.

Not sure which one fits?

Call if all three are true:

  • You worked in recent years.
  • You stopped because of a health or medical condition.
  • You're not working, not on leave and not job hunting.

No recent work of your own, or applying for SSI only? SSA can help you directly at ssa.gov.

Read SSA's SSDI work rules. For SSDI, younger workers may need fewer work credits.

Can you get both?

SSA says many people who are eligible for SSI may also be eligible for Social Security benefits. A separate application may be filed for each program so SSA can decide eligibility for each one.

SSI has other rules

Children with disabilities or who are blind may also get SSI. To get SSI, you must also be a U.S. citizen or national, or a noncitizen in certain categories. You must live in one of the 50 states, the District of Columbia or the Northern Mariana Islands, and not be outside the U.S. for a full calendar month or 30 or more days in a row. In most states, SSI recipients can also get Medicaid.
