Priority Mail Express packaging provided by the USPS must be used only for Priority Mail Express. The USPS-produced Priority Mail Express Legal and Padded Flat Rate Envelopes are not available at retail Post Office locations but may be ordered online at www.usps.com/store.
When sealing a Flat Rate Envelope, the container flap must be able to close within the normal fold. Tape may be applied to the flap and seams to reinforce the container provided the design of the container is not enlarged by opening the sides, and the container is not reconstructed in any way.
Any matter bearing a USPS-provided Priority Mail Express label or single-ply Priority Mail Express label generated through Click-N-Ship or other USPS-approved method is charged the appropriate Priority Mail Express price.

For each Priority Mail Express item, the mailer must complete Label 11-B or Label 11-F, Label 11-HFPU for Hold for Pickup service, or a single-ply Priority Mail Express label generated through Click-N-Ship or a USPS-approved method. Mailers authorized to present 1-Day or 2-Day Priority Mail Express items using a Priority Mail Express Manifesting System are required to follow label preparation procedures in Publication 97, Priority Mail Express Manifesting Technical Guide.
[6-23-19] For editions of Priority Mail Express Label 11-B or Label 11-F printed on or after January 2012, a mailer sending a Priority Mail Express item, and requiring a signature, must instruct USPS to provide a signature by checking the “signature required” box on Label 11-B or Label 11-F or indicating a signature is requested on a single-ply commercial label. If the signature required box is selected, an image of the signature will be provided to mailers when accessing delivery information. A mailer must select signature service for Priority Mail Express COD, or Priority Mail Express with additional insurance.
For Priority Mail Express 1-Day Delivery, the mailer must determine whether the item is destined to a ZIP Code area to which Priority Mail Express 1-Day Delivery is offered from the point of origin. A Priority Mail Express 1-Day Delivery directory, showing detailed local information about Priority Mail Express 1-Day Delivery, is available at Post Offices. If the destination is not listed, the mailer must use Priority Mail Express 2-Day Delivery.
Form 3877 is available at no cost to any mailer who mails an average of three or more Priority Mail Express items at one time, following these instructions:
- Form 3877 must be presented with the items to be mailed.
- The mailer must enter on Form 3877 the full number of each Priority Mail Express item and the addressee’s name and address.
- All entries must be made in duplicate. One copy is kept by the accepting employee. The other is receipted and returned to the mailer.
