Do I need to type FNC1 or register a product here?

No. Enter the GS1 field numbers in parentheses as shown; the encoder adds FNC1 separators where needed and validates supported field rules. Creating the image does not assign or register a GTIN. For ordinary text choose Data Matrix; for a GS1 web address choose GS1 Digital Link Data Matrix.

How do I check the code before printing?

Leave the white margins intact, keep the image in proportion and scan a sample at its final printed size with the device you intend to use.

Using GS1 DataMatrix

GS1 DataMatrix puts structured product and traceability information in a compact square code. Unlike ordinary Data Matrix, each field has a defined meaning, so compatible systems can distinguish a product identifier from a batch or date. Use the identifiers and fields required by your receiving system.

Download PNG for documents or SVG for a sharp, resizable print layout. Generation takes place in your browser, without an account.
