(aka USPS 4CB, OneCode Solution Barcode, OneCode ACS) The Intelligent Mail® barcode (formally known as the 4-State Customer Barcode) is the next generation of USPS® bar code technology used to sort and track letters and flats. Intelligent Mail® bar code technology, among other things, combines the capabilities of the POSTNET barcode and the Planet Code® bar code into one unique bar code. The 31-digit Intelligent Mail barcode (65 bars) is slightly longer than the 11-digit POSTNET barcode (62 bars), and it offers mailers certain flexibility in choosing the height and width of the bar code.
