Flats Sequencing System Presort Level ID Codes — As more mailers begin to adopt the optional Flats Sequencing System (FSS) bundle preparation standards, the Intelligent Mail® barcode system needs a way to indicate that level of presort. Barcode ID 20, currently used for optional endorsement line (OEL) 5-digit and 5-digit scheme presorts, has been extended for use on flats prepared under the rules for optional FSS bundle preparation.


The barcode ID tables have been updated in the Barcode ID table and Technical Resource Guide on RIBBS®. Clarifying the use of Barcode ID 20 for FSS OEL will not affect systems using Barcode ID information, but rather enable the Intelligent Mail barcode system to reflect bundles prepared under the FSS optional preparation.
