The Commission recently completed relocation of its headquarters to 1050 First Street, NE, Washington, DC. The agency’s zip code remains 20463 for those using the U.S. Postal Service (USPS) for delivery. However, mail sent via delivery services such as FedEx, UPS, and DHL should use the zip code 20002, which reflects the agency’s new physical location.
