The United States Postal Service expects to handle 13 billion pieces of mail, 800 million of them packages, this holiday season, and its North Texas processing and distribution center in Coppell will take part in processing a bulk of that.

The week of Dec. 16 is expected to be the USPS’ busiest week across the country, according to a news release.

Those concerned about the security of package delivery during the holiday season can customize their delivery schedules through USPS’ Informed Delivery service, postal inspector Sean Smith said.

Users can reschedule, hold and redirect their packages using the Informed Delivery service.
