OneCodeThe component is used to create the OneCode barcode symbol. It's defined in the pOneCode unit.

The OneCode barcode symbology is also known as Intelligent Mail barcode, IMB, 4-State Barcode, USPS OneCode Solution or USPS 4-State Customer Barcode (abbreviated 4CB, 4-CB, or USPS4CB). It is a 65-bar code for use on mail in the United States. It combines routing ZIP Code information and tracking information into a single 4-state code. It effectively encodes data from POSTNET and PLANET barcodes into a single barcode while providing a greater range of tracking data. The hope is that it may provide information and benefits to both mailers and postal officials.
