1. Introduction to Intelligent Mail Barcode (IMb) |
The Intelligent Mail Barcode (IMb) is a type of postal barcode developed by the United States Postal Service (USPS). IMb, introduced as an evolution of previous postal barcodes, was designed to increase the amount of data encoded, improve mail tracking capabilities, and optimize the overall efficiency of the mailing system. This 65-bar linear barcode contains a wealth of information, including details on sorting and tracking, which enables USPS to manage and trace individual pieces of mail with higher accuracy. As IMb plays a central role in USPS operations, its current status and future development are essential for the future of mail services. |

|
2. Structure and Technology of IMb |
2.1 IMb's 65-bar structure uniquely combines four distinct bar heights that create 31-digits of data. These bars are strategically coded to provide greater data density and storage, allowing for improved information processing compared to older barcodes, such as POSTNET and PLANET. |
2.2 The encoded information consists of five major components: |
Barcode Identifier (BI): A two-digit identifier providing information about the type of IMb used. |
Service Type Identifier (STID): A three-digit code that specifies the class of mail, including whether it includes special services, such as tracking or insurance. |
Mailer Identifier (MID): A unique identifier that links the mail piece to the specific sender or mailer. |
Serial Number: A unique number assigned to each mail piece, aiding in mail tracking and management. |
Delivery Point ZIP Code: Up to 11 digits corresponding to the destination ZIP code. |
2.3 IMb's design also allows for multi-channel data extraction, utilizing optical scanning technologies that interpret bar height and spacing to gather data on the mail piece's delivery journey. This approach contributes to both accuracy and cost-effectiveness by reducing the need for additional labeling or coding. |

|
3. Current Applications of IMb |
3.1 Mail Tracking and Delivery Confirmation: IMb enables USPS to track individual mail pieces as they move through the postal system. Through its Service Type Identifier, IMb supports delivery confirmation, providing both USPS and the sender with real-time updates on delivery progress and final delivery times. This has been instrumental in improving USPS's transparency and reliability. |
3.2 Enhanced Sorting and Routing: The ZIP code information within IMb facilitates precise routing of mail pieces, ensuring that each item reaches its destination efficiently. Sorting machines read IMb and route mail through various postal hubs, reducing sorting times and minimizing human error in the sorting process. |
3.3 Support for Digital Services: IMb integrates with Informed Delivery, a digital service provided by USPS that allows customers to preview their incoming mail online. The IMb allows USPS to capture images of mail pieces and make them available to recipients via email or the Informed Delivery dashboard, enhancing customer satisfaction. |
3.4 Analytics and Performance Tracking for Businesses: Many businesses that rely on direct mail marketing leverage IMb to measure the performance of their campaigns. Using the data captured by IMb, companies can determine delivery rates, understand geographic distribution, and identify any delays or issues within specific ZIP codes. |
