  • 1-Day Freight, Standard Overnight, Priority and First Overnight: Dec. 22
  • Same Day, Same City Priority and Same Day Direct: Dec. 23

United States Postal Service (USPS)

  • Retail Ground (medium and large packages): Dec. 17

The United States Postal Service says this week, Dec. 12 through 16, is the busiest mailing, shipping, and delivery week of the year. The second busiest is next Monday and Tuesday, Dec. 19 and 20.

No matter which delivery service you choose, the sooner you get your package on its way, the better. Although the deadlines should have your package arriving by Christmas, they do not account for possible delays caused by weather.
