The Intelligent Mail® package barcode (IMpb) is the U.S. Postal Service’s® bridge between physical packages and digital information, helping to deliver world-class service and tracking. In this three-part series, we’ll cover everything you need to know about IMpb. First up, we’re taking a look at how the IMpb is beneficial for businesses, which parcels require the barcode and the exceptions to that rule.

How Does the IMpb Benefit Businesses?

There are two key benefits: tracking and savings. By tracking every package, the USPS can anticipate mail volume, type and destinations, allowing them to operate more efficiently. The more information the USPS has, the better able they are to optimize operations, delivery, staffing and equipment throughout their network of processing facilities. This translates into a higher-quality, more time-efficient and less costly service for businesses.

With the IMpb, businesses benefit by receiving piece-level, end-to-end tracking information at no additional charge, for most products. Not only does this give you peace of mind, but being able to access package status and location at any time allows you to provide better customer service. You can proactively manage customer expectations on shipment arrival and seamlessly help eager customers check on their package status. Businesses can even provide their clients a link to track the packages themselves.  

The IMpb delivers unparalleled savings: the best commercial price, with the largest discount available. Using the IMpb also means that you get automatic insurance, up to $50 for Priority Mail® and $100 on Priority Mail Express®. Plus, the barcode is mandatory on all commercial mailings, so being proactive will help you avoid non-compliance fees. We’ll also be covering compliance in greater detail later on in this series.

Which Parcels Need an IMpb? 

The IMpb barcode is required on all commercial parcels, or any parcel entered through any commercial channel. Parcels can be of any shape, size or price category. This includes, but is not limited to:
