Departments and Agencies

Find the federal department, independent agency, bureau, or office connected to the service, record, rule, benefit, or public information you need.

Federal departments and agencies carry out laws, deliver services, write rules, publish data, manage grants and benefits, and provide official forms, records, and help portals.

Government works best when people can see how power is used and where decisions are made.

Cabinet Departments

The 15 Cabinet departments are the largest executive departments. Each is led by a Secretary or, for the Department of Justice, the Attorney General. Those officials are nominated by the President and confirmed by the Senate. Cabinet departments often contain many bureaus and offices, so a visitor looking for a public service may need the department first and the specific bureau second.

Independent Agencies And Commissions

Independent agencies and commissions are created by Congress to carry out specialized duties. Some operate public services, like the Postal Service. Others regulate markets, enforce civil-rights or workplace laws, insure deposits, run archives, or publish data. Their independence varies. Some leaders serve fixed terms. Some boards are bipartisan by statute. Some still answer closely to presidential direction.

Bureaus And Operating Components

Many familiar federal offices are not standalone departments. They are bureaus, administrations, services, or operating components inside a parent department. The FBI sits inside the Department of Justice. The IRS sits inside Treasury. TSA and FEMA sit inside Homeland Security. CDC, FDA, NIH, and CMS sit inside Health and Human Services. The parent department matters because it affects budgets, leadership, oversight, and official source trails.
