You can purchase a US flag that has flown over the United States Capitol building in Washington, D.C., by ordering it from your US Senator or US Representative. In fact, this is the only way to purchase one of these flags.
Certificate of authenticity. You may request that your flag be flown on a certain date such as a birthday or anniversary. A certificate showing it was flown over the Capitol accompanies each flag. If you mention in your letter or on your request form that this flag is for any specific occasion, that information will be included on the certificate. If you are requesting a specific date, please make your request at least 4 weeks prior to that date.
Fabric and size of flags. All flags are made in the United States. The cotton flags come in two sizes: 3’x5’ or 5’x8’. The nylon flags come in the same size as the cotton and one additional size: 4’x6’.
Prices. According to a survey we recently conducted, the specific prices vary from office to office. The prices include only the costs of the flag itself, the certificate, and shipping and handling. The payment must be a check or money order made payable to the fund designated by the specific Congressional office.
Order information. Most web sites of Representatives and Senators have a page devoted to the process for ordering flags from their offices. Check for a link to "Constituent Services" or "Services" for the ordering information for that office. If you find that the web site does not tell how to order a flag, please call the State or field office of the member of Congress for the information.
Additional questions. If you need any additional information or assistance about this issue or on other questions about the Federal Government’s agencies, programs, and services, please call the National Contact Center toll-free at 1-800-FED-INFO. It is open for personal assistance from 8:00 a.m. to 8:00 p.m., eastern time, Monday through Friday, except on Federal holidays.
