GS1 DataBar is a barcode symbology formerly known as Reduced Space Symbology (RSS-14)

This family of barcodes includes:

GS1 DataBar Omnidirectional

GS1 DataBar Stacked Omnidirectional

GS1 DataBar Expanded

GS1 DataBar Expanded Stacked (incl. US Coupons)

GS1 DataBar Truncated

GS1 DataBar Limited

GS1 DataBar Stacked

All GS1 DataBar barcodes encode a GTIN-12 or GTIN-13 numbers in a 14-digit data structure. In order to make the GTIN-12 or GTIN-13 a 14-digit data structure, a leading zero or zeros is filled to the left of the GTIN. GS1 DataBar Omnidirectional, GS1 DataBar Stacked Omnidirectional, GS1 DataBar Expanded, and GS1 DataBar Expanded Stacked have omnidirectional scanning capability.

GS1 DataBar Truncated, GS1 DataBar Stacked and GS1 DataBar Limited can only be scanned by a linear hand held or imaging scanning device: they cannot be scanned by omnidirectional scanners and are intended to be read by handheld scanners.

GS1 DataBar Stacked Omnidirectional is designed to condense the GTIN information into a more compact and square barcode suitable for use on smaller packages (such as the label stickers on fresh produce).

GS1 DataBar Limited, GS1 DataBar Stacked and GS1 DataBar Truncated are designed for very small item identification and are mainly used in the healthcare industry. Each encodes a GTIN-12 or GTIN-13 in 14-digit data structure. Only GS1 DataBar Limited uses an indicator digit 1.

In addition to encoding Application Identifier (01) GTIN, GS1 DataBar Expanded and GS1 DataBar Expanded Stacked can encode additional GS1 Application Identifiers such as sell-by date, weight, and lot number. Each symbol has a capacity of up to 74 characters. These attributes can help in controlling shrinkage, optimizing product replenishment, and improving the traceability of a product at the point of sale. They are seeing increased use in manufacturers' coupons. Starting June 2011 GS1 Databar use is mandated for coupons in the US and the use of UPC-A (for coupons) must be discontinued.

GS1 Databar Limited barcode

GS1-Databar Truncated
Reduced height variation of the GS1 DataBar Omnidirectional Bar Code that is designed for small items that will not need to be read by omnidirectional scanners.

GS1 Databar Truncated barcode

GS1-Databar Stacked
GS1-Databar Stacked is a GS1-Databar Truncated two-row format.
GS1-Databar Stacked may be used for small items instead of GS1-Databar Limited when the available space is too narrow for GS1-Databar Limited.
Moreover, the narrower width of GS1-Databar Stacked might allow for a larger X dimension and potentially higher print quality.

DB Stacked

GS1-Databar Expanded Stacked
A multi-row stacked variation of GS1 DataBar Expanded designed to be read by an omnidirectional scanner such as a retail slot scanner.

GS1 Databar Expanded Stacked

GS1-Databar US Coupon
