USPS Bar Code

This 65-bar code is what the USPS had been using as a tracking system. The Intelligent Mail barcode is a USPS service offered for domestic mail delivery. This tracking system is here to provide functionality and efficient information than its predecessors POSTNET and PLANET. Also known as One Code Solution and $-State Customer Barcode (4CB, 4-CB or USPS4CB), this code effectively incorporated the routing ZIP code and mail tracking information which was included in previously used postal barcode standards.

This Intelligent Mail was introduced by the US Postal Services in 2003 and was used by the fall of 2009 for mailers to receive maximum USPS automation discount. This new system features an improved deliverability, new services and increased overall mail efficiency. The code contains four distinct symbols hence the name 4-State Customer Barcode that encodes up to 31 decimal digits of mail-piece data into 65 vertical bars which is shown through a window envelope.
