Build Your GS1-128 Barcode

Add product, batch, expiry and serial information using GS1 Application Identifiers.

GS1-128 should be used according to GS1 specifications and trading-partner requirements. Generating an image does not certify compliance. Parentheses in human-readable text are AI notation only.
What are GS1 Application Identifiers?

AIs are standard prefixes (like 01 for GTIN, 17 for expiry) that tell systems what each piece of data means. Click an AI below to add it.

    What should your QR Code contain?

    Data Matrix is a compact 2D barcode for industrial and product applications (ECC200).

      Choosing a symbology does not assign an official product identifier. Retail GTINs must be obtained from GS1 or an authorized agency.

      Important: Generating a barcode image does not automatically assign an officially registered product identifier. Retail identifiers such as GTIN/EAN/UPC may need to be obtained from the appropriate issuing organization, such as GS1. Always verify your barcode requirements before using a barcode commercially.

      Barcode vs QR Code

      Linear barcodes store limited data in a strip of bars. QR codes store more data in a square matrix and are ideal for websites, product information and contact details.
