All Media Mail must bear a delivery address. The delivery address on each piece must include the correct ZIP Code or ZIP+4 code. Alternative addressing formats under 602.3.0 may be used. Each piece must bear the sender's return address.
The basic required marking—"Media Mail"—must be printed on each piece. The basic required marking must be placed in the postage area (i.e., printed or produced as part of, or directly below or to the left of, the permit imprint indicia or meter stamp or impression). Optionally, the basic required marking may be printed on the shipping address label as service indicators composed of a service icon and service banner (see Exhibit 102.3.3, Package Services Indicator Examples). The service icon that will identify Media Mail is a 1-inch solid black square. If the service icon is used, it must appear in the upper left corner of the shipping label.
