The USPS has made a major commitment to processing mail via
"automation". This is the processing of the mail by Optical Character Readers
(OCR) and Barcode Readers (see dictionary). The USPS offers postage discounts on mail that
qualifies for automation. To qualify mail for automation discounts, strict address and
design criteria must be met. Addresses must be in "standardized" formats, have
zip+4 codes, and be barcoded and sorted to various levels. Mailing pieces meet standards
of paper quality, specific sizes, and designs.
The University of Missouri has purchased computer software and MU Bulk
Mail has purchased the equipment to process mail to meet these USPS automation
