What is a GS1 DataBar Stacked Composite barcode?
GS1 DataBar Stacked Composite starts with the narrow two-row DataBar Stacked and places a 2D Composite Component above it. The result is a tall, thin symbol that carries a GTIN-14 plus data such as an expiry date, batch or serial number.
It is a choice for very narrow items like vials, small tubes or individual fruit where width is the main constraint. The stacked linear part has short rows, so it is meant for handheld or imaging scanners rather than omnidirectional checkout scanning.
What data can GS1 DataBar Stacked Composite hold?
(01) and a 14-digit GTIN for the DataBar part, then a | character, then GS1 Application Identifiers in brackets, for example (01)03412345678900|(17)010200.
Recommended size
Plan for a narrow but tall symbol. Print the row separators and the 2D block sharply, and test with an imaging scanner.

Frequently Asked Questions
In GS1 dates, a day of 00 means the last day of that month. (17)010200 is an expiry date at the end of February 2001.
Use Stacked Omnidirectional Composite if the item must scan at a fixed checkout. Plain Stacked Composite is smaller but needs a handheld or imaging scanner.
Yes. Write them one after another, like (17)261231(10)LOT42. More data makes the 2D block taller.
