Click-N-Ship is a service offered by the United States Postal Service which allows customers to create pre-paid shipping labels on standard printing paper. This covers the postage due and includes a free delivery confirmation number to show the date and time of delivery or an attempted delivery. Minus the cost of postage, there is no fee for users to create labels for Priority Mail, Express Mail, Global Priority Mail or Global Express Mail. For both domestic and international Priority Mail and Express Mail, postage offered through Click-N-Ship is discounted from retail rates.
After affixing the label, customers can ship the package by dropping it in a mail box, bringing it to a post office, giving it to their regular mail carrier, or requesting a special pickup.[1]
