GS1 DataBar Stacked Omnidirectional — Barcode Format Guide & Generator

GS1 DataBar Stacked Omnidirectional is a one-dimensional linear symbology in the GS1 DataBar family. Two-row stack, omnidirectionally scannable. Look for DataBar on loose and weighed fresh food, on coupons, and on small retail packs where a full EAN-13 would be too wide for the packaging.

Generated live in your browser by the same encoder the studio uses — nothing is uploaded.

Category: GS1 DataBar
Symbol: Linear (1D) bars
Data: Plain text within the symbology’s character set and length limits
Example: 9889876543210

Data format

Enter the payload as plain text. The encoder enforces each symbology’s character set and length rules, and rejects out-of-spec input with a clear message instead of silently producing a bad symbol.

Strengths and limitations

Strengths

Carries GS1-structured data that retail and healthcare systems understand natively.

Limitations

Only newer point-of-sale scanners read it — legacy checkouts may not.

Scanning and printing tips

Keep symbols at their nominal size: GS1 retail scanning assumes standard dimensions.
Leave the quiet zones clear — blank space on both sides of the bars is part of the symbol.
Print dark bars on a light background; red-only bars can vanish under red laser light.
Keep the bars vertical to the scan direction and print at the symbol’s standard magnification.
Verify one printed sample with a real scanner before committing to a full run.
