Example Barcode

The following example barcode encodes the information 0109501101530003 as an GS1 Databar barcode:

GS1 Databar Barcode


The GS1 Databar barcode family consists of seven symbols. This family can be split into two groups: those for POS (Point of Sale) use (Omnidirectional, Stacked Omnidirectional, Expanded, and Expanded Stacked), and those not for POS use (Stacked, Truncated, Limited). GS1 Databar barcodes employ a checksum as an error detection mechanism. 1, 2

Information for the POS symbols can be seen in the table below:

Omnidirectional Omnidirectional 14 Numeric Omnidirectional
