What is a GS1 DataBar Limited Composite barcode?
DataBar Limited Composite combines DataBar Limited, the narrowest single-row DataBar, with a 2D Composite Component. It keeps a small footprint while adding data such as a serial number, batch or expiry date, which is useful for traceability on small medical and healthcare items.
The linear part follows DataBar Limited rules, so the GTIN's first digit must be 0 or 1. It is intended for handheld and imaging scanners, not omnidirectional checkout scanning.
What data can GS1 DataBar Limited Composite hold?
(01) and a 14-digit GTIN starting with 0 or 1, then a | character, then GS1 Application Identifiers in brackets, for example (01)03512345678907|(21)abcdefghijklmnopqrst.
Recommended size
Use it where the label is both short and narrow. Keep the 2D data short, keep clear space around the symbol and scan with an imaging scanner.
