Where can the barcode be placed on the address side of a mailpiece?

The barcode on the address side of a mailpiece must be positioned at least ⅛ inch from any edge. This placement is crucial to ensure that the barcode is readable and can be scanned accurately by postal equipment. The specified distance helps prevent any interference from the edges of the mailpiece, which can occur due to trimming or when the mail is being processed. A proper placement also aids in maintaining the integrity of the barcode by keeping it clear of potential damage from folding or handling.

Positioning the barcode too close to the edges may compromise its visibility and scannability, hence adhering to the ⅛ inch guideline is essential for optimal processing and delivery efficiency.
