The preferred location for the delivery address is determined by the size and dimension of the mailpiece. The address placement for a letter is within the Optical Character Read (OCR) area. The address placement for a flat is determined by the top edge and construction of the mailpiece. In all cases, the delivery address must be on the same side as the postage. Refer to the DMM for the proper placement of the address and other elements on the face of a mailpiece.
When the Intelligent Mail barcode appears in the address block, it must be placed either above the address block or immediately below the optional endorsement and/or keyline information. Refer to the DMM for additional criteria and options for placement of the address and the Intelligent Mail barcode on mailpieces.
