Busiest Week

The notion of a “busiest day” is a thing of the past, thanks to the increase in early and online gift shopping. Customer mailing and shipping traffic is expected to increase beginning Dec. 10, and the Postal Service expects to deliver nearly 200 million packages per week during these two weeks. The week of Dec. 17-23 is predicted to be the busiest mailing, shipping and delivery week, when nearly three billion pieces of First-Class Mail, including greeting cards, will be processed and delivered.
