Expedited Delivery of Letters to Congress

Whenever time sensitive material must be delivered to a member of Congress without delay, you can use expedited delivery. Security procedures permitting, expedited delivery can be used to send unsealed mail through the Senate or House mail distribution facilities. These deliveries are accepted at the Congressional Acceptance Site, aka Congressional Courier Acceptance Site, 160 D Street NE, Washington, DC.
