Busiest Mailing and Delivery Days
The Postal Service’s busiest time of the season peaks two weeks before Christmas, when much last-minute shopping starts. The week of Dec. 16 is expected to be the busiest time for mailing, shipping and delivery. Additionally, the Postal Service predicts that nearly 2.5 billion pieces of First-Class Mail, including greeting cards, will be processed and delivered the week of Dec. 16.

Skip the Trip and Ship Online
Consumers can use to ship their packages and save trips to the Post Office. The Postal Service anticipates Dec. 16 will be the busiest day online with more than 8.5 million consumers predicted to visit for help shipping holiday gifts. Nearly 105 million consumers are predicted to visit between Thanksgiving and New Year’s Day.

The Postal Service receives no tax dollars for operating expenses and relies on the sale of postage, products and services to fund its operations.
