Adapted from

The Intelligent Mail® barcode, formerly referred to as the 4-state customer barcode, is a new Postal Service barcode used to sort and track letters and flats.  The Postal Service is promoting use of the Intelligent Mail® because it expands the ability to track individual mail pieces and provides customers with more options and information about their mail.

The Intelligent Mail® barcode combines the data of the existing POSTNET and the PLANET Code barcodes, as well as other data, into a single barcode.  The Intelligent Mail® barcode is a type of height-modulated barcode, that uses four distinct vertical bar types (Full, Tracker, Ascender and Descender).
