There have been several IFS newsletters that have featured information on the new Intelligent barcodes replacing the old POSTNET versions. USPS is making this effective permanently in January, so we will need these new barcodes for any Courtesy or Business Reply Mail (BRM) before the end of the year. We have started replacing the POSTNET barcode now for many of our customers. You can find more information on how to get us these barcodes through this link at

Or you can get us your Mailer ID for Courtesy Reply, or both Mailer ID and Permit # for BRM, and we can get the barcodes for you. If you have any questions, please contact your sales representative today, or call 815-725-0633.
