Is SSI & Disability the same thing?

Supplemental Security Income (SSI) is a program financed through general revenues. SSI disability benefits are payable to adults or children who are disabled or blind, have limited income and resources, meet the living arrangement requirements, and are otherwise eligible. The monthly payment varies up to the maximum federal benefit rate, which may be supplemented by the State or decreased by countable income and resources. Social Security Disability Insurance (SSDI) is financed with Social Security taxes paid by workers, employers, and self-employed persons. To be eligible for a Social Security benefit, the worker must earn sufficient credits based on taxable work to be "insured" for Social Security purposes. Disability benefits are payable to blind or disabled workers, widow(er)s, or adults disabled since childhood, who are otherwise eligible. The amount of the monthly disability benefit is based on the Social Security earnings record of the insured worker. I hope this help.

i think they consider SSI and SSID two different. it seems like,anyway.it may be only due to age it started,i would call their local office.

Because it is a supplemental security income meant to help aged, blind and disable persons to help meet basic needs such as food, shelter etc.. then there's a chance your mother may not have gotten it since it is dependent on the amount of income your mother has. If she had too much money in the bank, or was getting any sort of pension then more than likely she did not get SSI. However the quickest way to verify is to check whether or not she received SSI at any given time.
