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-provided Priority Mail packaging is charged the appropriate Priority Mail price.
[10-9-08] To use a permit imprint, the pieces must be of identical weight and, unless all the pieces are in a weight category for which the price does not vary by zone, the pieces must be separated by zone when presented to the Post Office. Permit imprint pieces must bear a postal routing barcode (see 708.5.0). Flat-shaped mailpieces may bear a POSTNET or Intelligent Mail barcode (see 708.4.0) instead of the postal routing barcode.
