DataBar Omnidirectional / Stacked Omnidirectional
Overview
DataBar Omnidirectional and DataBar Stacked Omnidirectional barcode types allow encoding 14-digit numerical data streams. They support encoding Global Coupon Number (GCN) and selected Global Trade Item Number (GTIN) formats, i.e., GTIN-8, GTIN-12, GTIN-13, and GTIN-14.
If GCN or GTIN contains less than 14 digits, zeros are appended to the left side of the input message so that 14 characters are encoded in total.

Usage Scenarios
These barcode types have been introduced to facilitate retail point-of-sale operational tasks and are widely used to label various items that are difficult to mark, e.g. fresh food products, hardware, and jewelry.
Characteristics
Encoding Character Set
Numerical digits (0-9) can be encoded.
Barcode Structure
DataBar Omnidirectional
Barcodes consist of the following elements:
- Left guard pattern (narrow space, narrow bar)
- Left pair of data characters with a finder pattern including a check digit between them
- Right guard pattern (narrow space, narrow bar)
- Right pair of data characters with a finder pattern in between including a check digit
The first digit serves as a flag that determines whether this barcode is a part of a composite barcode. The following 13 digits are intended to store information.
The input message is divided into four segments placed between two finder patterns. Data characters in the left pair of characters have a width of 16 modules per character (4 bars and 4 spaces in total). Data characters in the right pair are composed of 15 modules each (4 bars and 4 spaces overall); finder patterns have the same width with the difference that the first one includes 3 spaces and 2 bars, and the second one comprises 2 spaces and 3 bars. Quiet zones are not needed.
DataBar Stacked Omnidirectional
Barcodes have the following structure:
- Top row composed of the left half of a DataBar Omnidirectional barcode (left finder pattern, the first character, a finder pattern, the second character) combined with a finder pattern of a bar and a space
- Separator pattern
- Bottom row comprising a finder pattern and the right half of the code (the fourth character, a finder pattern, the third character, the right guard pattern)
Quiet zones are not necessary.
Size Dimensions
Each DataBar Omnidirectional barcode is composed of 46 bars and spaces including 96 modules in total. To enable omnidirectional readability, DataBar Stacked Omnidirectional must have the height of each row of at least 33 modules, and the height of the separator pattern must be at least 3 modules.
Encoding Capacity and Data Density
These barcode types can be used to encode 14-digit numerical data streams.
Checksum Controls
Check digits that are computed based on the modulo 79 algorithm are included in finder patterns.
Advantages and Limitations
Such barcodes can be scanned omnidirectionally.
