Get Ready for the Busiest Mailing and Shipping Week

(UNDATED) — It’s the last week to get those holiday gifts and greetings in the mail by the recommended deadlines. This week is expected to be the Postal Service’s busiest week of the holiday mailing and shipping season.

This has been an extraordinary year of unprecedented challenges given the COVID-19 pandemic — and the Postal Service is expecting significant increases in the volume of mail and packages. Sunday delivery has been expanded in select high package volume locations, and the agency already delivers packages on Sundays in most major cities. Mail carriers will also deliver Priority Mail Express packages for an additional fee on Christmas Day in select locations.

Important Reminders

  • Mail and packages weighing more than 10 ounces and/or measuring more than a half-inch thick and using stamps as postage cannot be dropped into a collection box or left for a carrier to pick up. Instead, take them to a retail associate at your local Post Office. This requirement does not apply to Click-N-Ship customers.
  • Certain items may have restrictions or prohibitions when it comes to sending through the mail. Please see the list of hazardous, restricted and perishable mail or ask a Postal Service employee for more information on what can and can’t be sent through the mail.
  • Battery-operated devices may turn on and make noise in transit. To prevent this, remove batteries from any battery-operated device, if possible, or make sure the device it turned off. Wrap and place the batteries next to the items in the package. Customers should include new batteries in the unopened, original manufacturer’s packaging if at all possible
