What is Expected Delivery Window?

When checking the status of your item, you may see a message about the Expected Delivery Window (ExDW). This window is a 2-hour slot of time when you can expect your package to arrive. Delivery within that time is not guaranteed, however, you may still receive your item by the end of the day if it does not arrive within the expected time slot. Check USPS Tracking® for updated information.
