Your local SSI Office is most likely in the same location as your closest SSA (Social Security Administration) Office. Though the two programs are separate and funded by different sources, they are often housed in the same building. The SSA is an umbrella program, which includes Medicare, Medicaid, card services, payments to the elderly and disabled and survivors' benefits, as well as SSI. To find the local SSA Office, one can visit its Web site at www.ssa.gov or call the toll-free number: 1-800-772-1213. This phone line is staffed from 7a.m. to 7p.m. Monday through Friday. Calls are confidential and are often monitored by a second SSA representative, to ensure that each individual receives accurate and courteous service.
