The choice between the several options (Chick Chack, FedEx, UPS, USPS) depends upon the time sensitivity of the package in question. For urgent local, same-day service, Mail Services uses Chick Chack Messenger Service at 212.244.8577. For overnight service, FedEx has the best service available (Priority - next morning, Standard overnight, Economy 2-Day, and 3-day service), for which The New School has a daily 4:00 p.m. pickup in Mail Services at 55 West 13th Street, lower level. For less urgent deliveries and packages going to a P.O. box, the USPS offers Express Mail (overnight), Priority Mail, and Parcel Post. Please call Mail Services for rates and additional information.
