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 get SSI benefits for the entire time since the date you applied. That’s why you should apply as soon as possible. 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 you can.

Getting Your Application Ready

When you apply for SSI, you 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.


  • 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


  • 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


  • A list of the types of jobs you’ve done for the past 15 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


  • 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.

Aid to the Needy Disabled - State Only (AND-SO)

While you wait to find out if your application for SSI is accepted (it can take months), you might be able to get a temporary cash beneft from Colorado's AND-SO program. For 2024, the maximum AND-SO benefit is $248 a month. Note: When SSI starts, some of your retroactive SSI benefits will automatically be used to pay back the AND-SO program.

For more details or to see if you can get AND-SO benefits, contact your local county human services department.

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, apply for other benefits, like:

The Colorado PEAK website (Program Eligibility and Application Kit) can help you:

  • Figure out which state benefits might help you
  • Apply for those benefits, and
  • Manage those benefits once you get them.

Note: If you are 60 or older, you might get help through Colorado's Old Age Pension (OAP) program. It gives cash benefits to Colorado residents 60 and older who have low income and low resources. To learn more, contact your local county human services department, or apply for OAP online through Colorado PEAK.
