Intelligent Mail® Barcodes (IMb) are required on all automated mail.
The Intelligent Mail barcode is the next generation of USPS® barcode technology used to sort and track letters and flats. Intelligent Mail barcode technology, among other things, combines the capabilities of the POSTNET™ barcode and the PLANET Code® barcode into one unique barcode.
The Intelligent Mail® barcode:
When used to qualify for an automation price, the Intelligent Mail® barcode follows the same placement rules as POSTNET barcodes. On letters, it can be placed in the address block or in the barcode clear zone found on the lower right corner of the envelope. On flats, the Intelligent Mail® barcode can be placed anywhere on the address side as long as it is at least 1/8 inch from any edge of the piece.
Will I need to complete CASS™ or MASS™ certification again?
The Multi-line Accuracy Support System (MASS) certification is an extension of CASS. It has an annual certification requirement and the Intelligent Mail barcode certification is now incorporated into this process.
