Priority Mail Express Refund for Late Delivery
Priority Mail Express has a guaranteed delivery date based on the Post Office where the mailpiece was dropped off, when it was dropped off, and the delivery zip code.
If your Priority Mail Express mailpiece is not delivered by the guaranteed time, you can request a refund at USPS.com. Refunds will no longer be processed at Post Office locations.
