A system and method for preparing a set of paired identification label based a plurality of characters that identify an inventory item. The method includes a step of assigning a predetermined numerical value to each of the plurality of characters. Mathematical operations are performed on the assigned numerical values to obtain a mapping of the plurality of characters to a corresponding non-textual visual indicator. A label is generated which label includes the plurality of characters and the visual indicator. The visual indicator may be a color or a graphic indicator such as an alignment designation bar or a combination and variation thereof.
