What do I need to open an account?
Make sure you have this information handy:
Social Security Number or Tax Identification Number;
Contact details; and
Proof of eligibility.
If you’re an Authorized Legal Representative, you’ll need the same information as the beneficiary’s, plus your work status.
If the beneficiary is not eligible for Supplemental Security Income (SSI) or Social Security Disability Insurance (SSDI) benefits, they need a signed Diagnosis Form from a licensed physician.
If you’re signing up by snail mail, you’ll need an Enrollment Form.
