2.0 Marking for Priority Mail

1.0 Preparation

1.1 Priority Mail Packaging Provided by the USPS

Priority Mail packaging provided by the USPS must be used only for Priority Mail. Regardless of how the packaging is reconfigured or how markings may be obliterated, any matter mailed in USPS-produced Priority Mail packaging is charged the appropriate Priority Mail price.

1.2 Sealing Flat Rate and Regional Rate Packaging

When sealing a Flat Rate Envelope, Flat Rate Box, or Regional Rate Box, the container flaps must be able to close within the normal folds. Tape may be applied to the flaps 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.

1.3 Required Use

The sender’s domestic return address must appear legibly on Priority Mail.

2.0 Marking for Priority Mail

The marking “Priority Mail” must be placed prominently on the address side of each piece of Priority Mail under 102.3.2.
