US Government Directory — Federal, State & Local Agencies

Complete directory of US government agencies and official websites. Find federal departments, Congress, state portals, court records access, FOIA resources, and open data. Updated April 2026.

The United States federal government comprises three branches — Executive (President and 15 Cabinet departments), Legislative (Senate and House of Representatives), and Judicial (Supreme Court and 94 federal district courts) — plus more than 400 independent agencies, boards, and commissions. State governments mirror this tripartite structure across all 50 states, with thousands of additional county and municipal agencies below them. Every branch generates public records: legislation, court filings, agency rulemaking, spending disclosures, FOIA releases, and open datasets. This directory connects you directly to the official government portals, public data repositories, and records-access systems at every level. Updated April 2026.
Federal Government Portal

USA.gov is the official entry point to all federal government services, agencies, and information. The General Services Administration (GSA) maintains it as the authoritative directory of the entire federal establishment.

Executive Branch — The White House & Cabinet

The Executive Branch is led by the President and consists of the Executive Office of the President, 15 Cabinet-level departments, and more than 68 independent agencies. The 15 departments together employ approximately 2.9 million civilian workers — the largest employer in the United States.

Legislative Branch — Congress

The U.S. Congress consists of the Senate (100 senators, 2 per state, 6-year terms) and the House of Representatives (435 voting members, apportioned by population, 2-year terms). Congress introduces approximately 10,000–15,000 bills per session; roughly 300–600 are enacted into law.

Judicial Branch — Federal Courts

The federal judicial branch consists of the Supreme Court of the United States (9 justices), 13 Courts of Appeals (circuit courts), 94 district courts, and specialized courts including the U.S. Tax Court, Court of International Trade, and Court of Federal Claims. All federal court records are accessible through PACER.

ℹ Note on PACER: Documents filed in federal courts after approximately 1996 are generally available through PACER. Older records require contacting the clerk's office directly or requesting from the Federal Records Center.

Open Data & Government Transparency

Federal law — including the OPEN Government Data Act (2018), the Digital Accountability and Transparency Act (DATA Act, 2014), and the Government Performance and Results Act — requires federal agencies to make data publicly available in machine-readable formats. The following portals provide free access to the primary federal open-data repositories.

FOIA & Public Records Access

The Freedom of Information Act (5 U.S.C. § 552), signed by President Johnson in 1966 and significantly amended in 1996 (E-FOIA Act) and 2016 (FOIA Improvement Act), grants every person — regardless of citizenship — the right to request records from any federal executive branch agency. Agencies must respond within 20 business days. In FY 2025, federal agencies collectively received more than 1.2 million FOIA requests.

ℹ FOIA Tip: Nine categories of records are exempt from mandatory disclosure, including national security information (Exemption 1), internal agency personnel rules (Exemption 2), trade secrets (Exemption 4), and personal privacy information (Exemption 6). Agencies may withhold exempt portions but must release the rest of the document.

State & Local Government Portals

Each of the 50 states, Washington D.C., and U.S. territories operates its own independent government with executive, legislative, and judicial branches. The U.S. Census Bureau's 2025 Annual Government Organization count identifies more than 90,000 distinct governmental units across the United States — including 50 state governments, 3,000+ county governments, 19,000+ municipal governments, 16,000+ townships, 12,000+ school districts, and 38,000+ special districts.

For state-specific public records — criminal records, court records, vital records, DMV, property — use our State Public Records directory to navigate directly to each state's official government agencies by record type.

Federal Employment & Spending

The federal government is the nation's largest employer with approximately 2.9 million civilian employees across all 50 states and territories, plus an additional 1.3 million active-duty military personnel. Understanding federal employment and spending data is essential for government contractors, researchers, journalists, and citizens tracking taxpayer funds.

Frequently Asked Questions

What is USA.gov and what can I find there?

USA.gov is the official web portal of the United States government, maintained by the General Services Administration (GSA). It provides a single point of access to all federal departments, agencies, and services — including benefit programs, government jobs, official contact information, and links to state government portals. It is the authoritative starting point for any interaction with the federal government online.

How do I file a Freedom of Information Act (FOIA) request with a federal agency?

Submit your request in writing (letter, email, or online form) directly to the FOIA office of the specific federal agency that holds the records you want. Identify the records as specifically as possible. Agencies must respond within 20 business days under 5 U.S.C. § 552. FOIA.gov provides a central portal listing every federal agency's FOIA contact information, reading rooms, and submitted-request logs. Many agencies now accept requests through FOIA.gov's MaPS (Multi-Agency Public System) directly.

How many federal agencies does the United States government have?

The precise number is debated because it depends on how "agency" is defined. The Federal Register officially lists approximately 441 agencies. The United States Government Manual lists 96 independent executive units plus 220 components of the 15 Cabinet departments. The Executive Branch alone includes 15 Cabinet-level departments, 68 independent agencies (such as the EPA, NASA, SSA, and FEC), and more than 300 advisory boards and commissions.

What is GovInfo.gov and what documents does it contain?

GovInfo.gov is the U.S. Government Publishing Office's (GPO) official digital repository of authentic government publications. It contains the Congressional Record (floor proceedings since 1873), the Federal Register (daily executive branch rules and notices), the Code of Federal Regulations (CFR), the United States Code (U.S.C.), Supreme Court slip opinions, the Budget of the United States Government, the Economic Report of the President, and thousands of other official documents — all freely searchable and downloadable.

How do I find my elected representatives in Congress?

Visit house.gov and enter your ZIP code to find your U.S. House member. Visit senate.gov to find your two U.S. senators by state. Congress.gov allows you to track all legislation introduced in both chambers, see full bill text, review voting records, and read Congressional Research Service (CRS) reports. For state legislators, use your state's official legislature website (e.g., legislature.ca.gov for California, capitol.texas.gov for Texas).
