Supplemental Security Income (SSI)

Apply for Benefits

You can apply for Supplemental Security Income (SSI):

  • Online (which starts the application process immediately)
  • By calling Social Security at 1-800-772-1213 or 1-800-325-0778 (TTY) to make an appointment to apply either:

Note: If you are approved, you will get SSI benefits for the entire time since the date you applied. That’s why you should apply as soon as you can. If you don’t have everything ready for your application, that’s OK — you can still apply and send any missing information as quickly as possible.

Getting Your Application Ready

When you apply for SSI, you’ll need to give Social Security:

  1. Basic facts, like your name, date of birth, and address

Note: You don’t need to have a fixed address. If you’re experiencing homelessness or don’t have a fixed address, you can still get SSI. Read Social Security’s Spotlight on Homelessness.

Bring:

  • Identification, like your driver’s license, state ID, or passport
  • Birth certificate
  • Proof of U.S. citizenship if you were born outside the U.S., like naturalization papers or your U.S. passport. If you are not a U.S. citizen, you must be a qualified alien who meets certain conditions. For more details, contact your local Social Security office.
  • Social Security Number
  1. Documentation of your medical condition

Bring:

  • Names, addresses, and phone numbers of doctors, therapists, hospitals, clinics, and others who have treated you
  • Prescriptions and results of medical tests
  • Documentation explaining how your medical condition affects your daily life

Be ready to:

  • Sign forms so Social Security can get copies of your medical records
  • Fill out forms about how your disability affects your daily life
  • Give Social Security permission to contact your employer, friends, or family to learn how your disability affects you
  1. Documentation of your income

Bring:

  • A list of the types of jobs you’ve done for the past 5 years
  • Copies of recent tax records or W-2 forms
  • Information about other benefits you get
  • School records, if you’re under 22
  1. Documentation of your resources

Bring:

  • Copies of bank statements

Be ready to:

  • Answer questions and give proof about any savings, retirement accounts, stocks, bonds, real estate, or other resources that you own

Social Security provides a detailed checklist of the information you need to complete the application process.

Apply for Other Benefits While Your SSI Application Is Reviewed

The SSI application can take four months or longer. While you wait for your SSI benefits to begin, you can apply for other benefits, like:

Go to MyDSS.mo.gov/qualify and answer a few simple questions to see if you qualify for these benefits. You can then apply online or at your Family Support Division (FSD) office by mail or in person.

If you need help with an application, talk to a Benefits Specialist.
