Our most popular publication, a detailed directory of Members of Congress, with their leadership roles, committee assignments, subcommittee assignments, Hill and District staff with legislative responsibilities, plus biographical details, phone, and email for all.

The Federal Yellow Book provides essential contact information for over 45,000 U.S. federal decision-makers located within the Washington, D.C. metropolitan area. Thousands of offices within each Department and Agency are displayed hierarchically, allowing users to easily understand the complex structure of the government. Users can quickly find federal officials and administrators in charge of purchasing, finance, IT, training, facilities, conferences, and more. The easy-to-use code system identifies political appointees by type: appointees who do and do not require Senate confirmation, non-career and career Senior Executive Service (SES) appointees, and Schedule C political appointees. All mailing addresses, exact titles, direct-dial telephone and fax numbers, biographical data, and emails are verified by our in-house editorial staff on a continuous basis.
