Central San Mateo County District Office

Social Security Administration (SSA)

Administers the Social Security program for the mid-county area.


A full service office that processes claims for all Social Security programs. Social Security benefits are based on the worker's wages and may be paid to the worker or the worker's dependents or survivors. People in need of cash aid who are age 65 or over, or who are blind or disabled including blind and disabled children, may apply for Supplemental Security Income (SSI). SSI recipients automatically qualify for Medi-Cal. Medicare is the federal health insurance program for people age 65 or over and those who are disabled or have chronic kidney disease. It is best to check first the Web site for information about qualifications and the necessary documentation which must be submitted. Interim emergency financial assistance may be obtained from the San Mateo County Human Services Agency. Applications for homebound persons can be handled by phone or mail. Original and duplicate Social Security cards are issued here. To request a speaker on Social Security, SSI or Medicare contact the office.
