The Intelligent Mail barcode is the next generation of USPS barcode technology used to sort and track letters and flats. It combines the capabilities of the POSTNET barcode and the PLANET Code barcode into one unique barcode. Bulk mail that is barcoded is eligible for additional USPS discounts. To qualify for these discounts, the USPS requires an accurate Zip + 4 code, which can be matched with CASS Certified software.

CDYNE's CASS Certified PAV Web Service will provide the following information and reports to qualify for USPS discounts:

  •  Append the required Zip + 4 to your database
  •  Provide CASS Summary Report (Form 3553) for barcoding discounts
  •  Return an Intelligent Mail barcode key, giving mailers the ability to generate Intelligent Mail barcodes
