Information technology -- Automatic identification and data capture techniques -- GS1 DataBar bar code symbology specification

The GS1 DataBar family contains three types of linear symbologies to be used with the GS1 system. The first type has four variations (GS1 DataBar Omnidirectional, GS1 DataBar Truncated, GS1 DataBar Stacked and GS1 DataBar Stacked Omnidirectional). The stacked variations are two-row symbols. The second type comprises only one variation, namely GS1 DataBar Limited. The third type has two variations, a single row variation (GS1 DataBar Expanded) and a multi-row stacked variation (GS1 DataBar Expanded Stacked). The use of GS1 DataBar is intended to comply with the GS1 application guidelines as defined in the GS1 General Specifications.

GS1 DataBar Omnidirectional and GS1 DataBar Stacked Omnidirectional encode a 14-digit GS1 item identification (often referred to as a Global Trade Item Number, or GTIN) in a linear symbol that can be scanned omnidirectionally by suitably programmed point-of-sale scanners. GS1 DataBar Truncated and GS1 DataBar Stacked encode a 14-digit GS1 item identification in a linear symbol and are not suitable for omnidirectional scanning. GS1 DataBar Limited encodes a 14-digit GS1 item identification with a leading digit of zero or one in a linear symbol for use o
