GS1 DataBar Stacked
GS1 DataBar Stacked is a GS1 DataBar Omnidirectional symbol that is reduced in height and split into two rows with a separator pattern between them. It is identical to GS1 DataBar Stacked Omnidirectional except that the total height is reduced to as low as 13 modules. As a result, this symbology cannot be accurately read omnidirectionally.
GS1 DataBar Stacked encodes a 14-digit numeric data stream. It supports the encodation of the Global Coupon Number (GCN) and the following Global Trade Item Numbers (GTINs): GTIN-8, GTIN-12, GTIN-13, and GTIN-14. If the GCN or GTIN has fewer than 14 characters, leading zeros are appended to the left of the data so that a total of 14 characters is encoded. Due to its compact size, this symbology is mainly used in the health care industry.
GS1 DataBar Stacked is defined in ISO/IEC 24724 Information technology - Automatic identification and data capture techniques - GS1 DataBar bar code symbology specification and the GS1 General Specifications document.
