Frequently asked questions
What are Application Identifiers?
Short numeric prefixes in parentheses — like (01) for GTIN, (10) for batch/lot, (17) for expiry date — that tell scanning systems what each following value means, as defined by GS1's standard.
Do I need a GS1 membership to use this?
For genuine supply-chain use with real GTINs, yes — GS1-128 is a labelling standard, not a licence; Mozaik just renders the barcode from the AI groups you provide.
