What Is The Intelligent Mail Barcode And What Does It Do?

The IMB is a 65-bar code that is used to track and sort flats and letters sent through the USPS. Mailers can use a single barcode for all their mail and can also participate in many USPS programs. Likewise, it can make tracking mail easier. It can be used for Priority Mail, First-Class Mail, Periodicals, Standard Mail, letters, flats, and even Bound Printed Matter flats.


In 2014, the USPS started requiring mailers to use the full-service Intelligent Mail Barcode software if they wanted to get automation discounts and were also required to use eDoc to upload their paperwork. Likewise, the IMB combines the PLANET Code and POSTNET barcodes into a unique code.


Primarily, this product can help you determine how much money you’ll need to spend for mailing campaigns, as well as determine how many employees you’ll need, based on the deliveries and options. You can also use it to plan your inventory and determine the accuracy of your mailing lists, as well as save money.
