GS1 / logistics

GS1 standards define Application Identifiers (AIs) -- structured data fields like GTIN, batch/lot, and expiration date -- carried inside symbologies such as GS1-128 and GS1 DataBar for supply-chain and logistics use.

Choosing a format

• GS1-128 is common on shipping labels and cartons where multiple AI fields (GTIN, SSCC, dates) travel together.
• GS1 DataBar and its composite variants suit small retail items and variable-measure goods (e.g. fresh produce) where a full GS1-128 symbol will not fit.
• This site explains and renders GS1 AI syntax; it does not assign GS1 company prefixes or certify GS1 compliance.
