Intelligent Mail Barcode(IMB) The Intelligent Mail Barcode (IMb) is a 65-bar Postal Service barcode used to sort and track mailpieces such as individual letters, cards and flats.

The barcode data is scanned and collected by the USPS - it captures information including service type, mail owner or mailing agent, plus a serial number to identify and track each mailpiece. It can be used for address correction services including manual address correction notices, Address Change Service (ACS), OneCode ACS®, and Intelligent Mail Full-Service ACS. Intelligent Mail barcodes must be generated by a solution or software that has been approved by the USPS.
