Disability Determination Services

What is the purpose of this service?

We are responsible for determining the eligibility of Illinois citizens to receive benefits under Social Security's disability programs. These programs are Social Security Disability Insurance (SSDI) and Supplemental Security Income (SSI).

Who can receive these services?

  • SSDI benefits are available to eligible individuals who are disabled and have been employed and made contributions to the Social Security fund through wage deductions.
  • SSI benefits are available to eligible individuals who are disabled and have limited income and resources.

An individual's eligibility for disability benefits is based upon medical evidence and whether the disability is expected to last a minimum of 12 months or for the remainder of the person's life.

How are services provided?

We provide services to 56 offices located in communities throughout the state. To find the nearest Social Security office, dial (800) 772-1213 and tell the service representative your city, state and zip code.
