342 Primary Considerations

The preferred location for the POSTNET Address Block Barcode is above the address block or immediately below the optional endorsement and/or key line information, if used. However, it may be placed below the address block if necessary. In either location it must be within 4 inches of the bottom and 1/2 inch from either edge of the mailpiece in order to be read by the barcode sorter. Refer to the DMM for additional criteria and options for placement of the barcode on mailpieces.
