USPS Priority Mail Express is the fastest mail service offered by the US Post Office that ships in one to two business days with guaranteed delivery or your money back. To ensure your USPS Priority Express shipment arrives on the scheduled delivery day and to be eligible for the Express guarantee, we recommend the following:
Ship Date
Make sure you have the correct ship date. If you need to postdate a shipment to be sent later, you can change it by clicking on Ship Date and selecting a new date from the dropdown calendar.
Use the USPS Verified Address
USPS Address Validation allows you to validate the mailing address you're sending to with the USPS address database. This validation ensures your mailing meets the requirements for guaranteed delivery time via the Express USPS services.
Select an order or enter the receiver's address information to verify an address.
If the address information is found by USPS, but not verified, a message appears with the text "Did you mean" under the quote. This message can mean that USPS has a verified version of that address, with the correct "+4 ZIP", Suite, Apt., or Street name.If this suggestion matches the address you are shipping to, click Use USPS verified address.
If your sender address is unverified, modify it by clicking the "Switch" icon to make the Sender and Receiver addresses switch places.
Click Use USPS verified address for the sender address as well and switch the addresses back.
To ensure smooth future shipments, consider modifying the default sender address to the USPS verified address in user management. For more details visit the Help Center article: How do I change my default sender address?
Estimated Arrival Date
When all details are filled out correctly, the shipment can be quoted. Within the quote is an Estimated Arrival Date. (This date is an Estimated Arrival Date and is not always the date guaranteed for delivery. For information on finding the guaranteed delivery date, please see the next section in this article.)
