The Social Security Administration (SSA) is a U.S. government agency that administers social programs covering disability, retirement, and survivors' benefits, among other services. It's also responsible for issuing Social Security numbers and managing the program’s finances and trust fund.

Unlike most U.S. government agencies, the SSA is headquartered in Baltimore, Maryland rather than Washington, D.C. The SSA has 10 regional offices, six processing centers, and approximately 1,230 field offices. It employs almost 60,000 workers.
