The placement of the address on the face on an envelope should conform to USPS specifications, as shown in the following example. If address labels are used on parcels, packages or large envelopes, they must be addressed according to the same recommended format. Improperly prepared labels will be returned to the sender for correction and/or completion. Labels that are applied must be parallel to the bottom edge of the envelope to be processed by USPS automated equipment.
- Address Area - The complete address should be located within this white area (no return address information). Extraneous (non-address) printing or markings should appear as high on the mail piece and as far away from the address as possible.
- Barcode Read Area - Please make sure that this area remains clear of all printing. It's reserved for the bar code that will be printed by the Optical Character Reader (OCR).
