Please note: The Congressional Acceptance Site cannot accept any perishable deliveries (e.g. flowers, food, drink, etc.).
The Congressional Acceptance Site will accept items from couriers with proper identification, (i.e., a valid driver’s license), Monday – Friday, 8:30 a.m. – 5:30 p.m. When a courier makes a delivery to the Congressional Acceptance Site, each item will be logged-in (noting the date and time), x-rayed and screened for hazardous materials and substances.
