The U.S. Postal Service (USPS) expects to deliver more than 28 million packages per day between December 16 – 21, and will average 20.5 million packages per day through the remainder of the year.

USPS expanded Sunday deliveries beginning November 24 to locations with high package volumes. Already delivering on Sundays in most major cities, it anticipates delivering more than eight million packages on Sundays during December. In select locations, mail carriers will also deliver packages for an additional fee on Christmas Day.

According to USPS, it plans for peak holiday season all year. This includes making sure the right equipment is available to sort, process and deliver the expected mail and package volumes. Seasonal workers are hired when and where needed, and technology is expanded to enhance package tracking throughout the USPS processing and transportation networks.

Busiest Mailing and Delivery Days
Customer traffic is expected to increase beginning December 9, while the week of December 16 is expected to be the busiest time for mailing, shipping and delivery. Additionally, USPS predicts that nearly 2.5 billion pieces of First-Class Mail, including greeting cards, will be processed and delivered the week of December 16.
