The World Trade Center site used the ZIP code 10048 before the September 11 attacks, and there were eight letter carriers assigned to the buildings to deliver mail to the buildings' tenants. All of the Postal Service employees survived the attacks. In the months following the September 11, 2001 attacks, over 80,000 pieces of mail continued to arrive each day addressed to the World Trade Center, including some items loosely addressed to such recipients as "The Search Dogs" or "The Rescuers". By 2003, 3,600 items of mail per day were still being sent to 10048. These items were processed at the James A. Farley General Post Office, the main facility for New York City, located across from Penn Station in Midtown Manhattan. Mail there was held for pick-up by messenger, forwarded to the intended recipient, returned to its sender, or destroyed.
