The GS1 DataBar Omnidirectional barcode is a linear symbology designed to encode a 14-digit numeric string, such as a Global Trade Item Number (GTIN) or Global Coupon Number (GCN). For shorter numbers, leading zeros are added to meet the 14-digit requirement.
The barcode spans 96 modules in width and 34 modules in height. Its structure includes left and right guard patterns, as well as two pairs of symbol characters, separated by finder patterns that incorporate check digits. The sequence for reading these characters is first, second, fourth, and third, with the middle characters read from right to left.
Quiet zones, or blank spaces, are required on both sides to ensure accurate scanning. The barcode supports numeric digits (0–9) and uses a modulo 10 algorithm to calculate check digits, enabling error detection.
With omnidirectional scanning capabilities, this barcode is ideal for retail point-of-sale systems, especially for fresh food and other products needing enhanced data encoding.
The GS1 DataBar Omnidirectional is a linear barcode symbology specifically engineered to encode a 14-digit numeric data string.

Width and Height Specifications
Width:
The total width of the barcode is 96 times the X-dimension, including quiet zones (blank spaces) on both sides.
Quiet zones are essential for preventing scanning errors and ensuring the barcode is correctly interpreted by retail scanners.
Height:
The minimum height of the barcode is 34 times the X-dimension.
For example, if the X-dimension is set at 0.264 mm (0.0104 inches), the barcode height would be approximately 8.98 mm (0.354 inches).
X-Dimension Range
The recommended X-dimension typically ranges from 0.264 mm to 0.660 mm (0.0104 to 0.0260 inches), depending on specific printing and scanning requirements.
Maintaining this range ensures compatibility with standard retail scanners and provides optimal performance.
Quiet Zone Requirements
Quiet zones (clear spaces) are mandatory on both sides of the barcode to avoid misreads. Their size must be at least 10 times the X-dimension on each side.
Importance of Adhering to Size Standards
Selecting the appropriate X-dimension and ensuring the barcode’s width and height conform to these specifications guarantees accurate scanning and seamless integration into retail and supply chain applications.
In summary, the GS1 DataBar Omnidirectional barcode’s ideal size is determined by the X-dimension, with a total width of 96X and a minimum height of 34X, along with mandatory quiet zones on both sides. This precise sizing ensures reliable performance in retail POS environments.

The GS1 DataBar Omnidirectional barcode encodes a fixed 14-digit numeric string in its linear component. This string typically represents a Global Trade Item Number (GTIN) or a Global Coupon Number (GCN). For GTINs or GCNs with fewer than 14 digits, leading zeros are automatically added to meet the 14-digit requirement.
When the GS1 DataBar Omnidirectional barcode is used as part of a GS1 DataBar Composite symbol, additional data can be included in the 2D composite component, which is either MicroPDF417 or PDF417 based. This component allows encoding of supplementary information such as batch numbers, expiration dates, or other application identifiers. The character limits for these components are as follows:
CC-A and CC-B (MicroPDF417-Based Formats):
These formats can encode up to 56 numeric digits or shorter alphanumeric strings.
CC-C (PDF417-Based Format):
This variant supports larger datasets, often used with GS1-128 barcodes.
The exact capacity depends on the length of the linear barcode and the available space for the composite component.
Linear vs. Composite Components
