Priority Mail Express postage won’t be refunded if the package was mailed between Dec. 22 and Dec. 25 and delivery was attempted or achieved within two days of the mailing date.
December 15, 2022
As it has done for years, the Postal Service will implement a no-refund policy for Priority Mail Express packages shipped from Dec. 22 through Dec. 25 under the following two conditions:• The one-day shipment was mailed between Dec. 22 and Dec. 25 and was delivered, and
• Delivery was attempted or achieved within two business days of the mailing date.
The policy is a response to the increased package volume and winter weather conditions that can affect the organization’s standard 1-2-day service commitment during these four days and is similar to that of competitors.
It is found in Section 604 of the Domestic Mail Manual.
