GS1 Australia barcode notes

GS1 Australia: https://www.gs1au.org/barcode-generator

• Use authentic GS1 GTINs for products sold through Australian retailers and marketplaces.
• EAN-13 and UPC symbols should encode assigned product identifiers, not random numbers.
• Use GS1-128, ITF-14 and SSCC labels for cartons, pallets and supply-chain workflows.
• 2D barcodes and GS1 Digital Link are increasingly relevant for richer product data and future retail scanning.

How this barcode generator works

Choose a barcode type, enter the data, and the preview updates in the browser. For EAN-13, EAN-8, UPC-A and ITF-14, the tool validates numeric length and can complete the check digit when you enter the body of the number. For Code 128 and QR Code, you can use letters, numbers and common business identifiers such as order numbers, SKU references or URLs.

The export controls are designed for real artwork workflows. Use SVG for packaging and label design because it stays sharp at any size. Use PNG when you need a quick image for a document, spreadsheet or label printer. Use the DPI, height, bar-width and quiet-zone controls to prepare a symbol that is easier to scan once printed.

1. Select the barcode type that matches the use case: EAN-13 for retail, Code 128 for internal labels, GS1-128 for logistics, ITF-14 for cartons, or QR Code for links.
2. Enter the GTIN, SKU, URL or GS1 element string. If the barcode will be used in retail, use an assigned GS1 number rather than a random value.
3. Check the preview, then adjust height, bar width, colours and quiet zone before exporting SVG, PNG or print output.
4. Test a printed sample with the scanner or retailer workflow that will actually read it.

Australian GS1 and retail barcode notes

GS1 Australia is the local member organisation businesses normally use to get authentic GTINs for products sold through Australian retailers and marketplaces. A free barcode generator can create an image, but it cannot make an invented number legitimate for retail distribution. That distinction matters because marketplaces, supermarkets and distributors may check whether a GTIN belongs to the brand or supplier submitting the product.

Australian retail products commonly use EAN-13 or UPC-A depending on the trading context. Cartons and cases may use ITF-14 or GS1-128, especially where a logistics label needs an SSCC, batch, expiry date or other Application Identifier data. For future-ready product information, QR Code and GS1 Digital Link are worth covering because they can connect shoppers and supply-chain partners to richer online product data.

• Retail packaging: use EAN-13 or UPC-A with an official GS1 GTIN.
• Internal inventory: Code 128 is usually flexible and compact.
• Outer cases: ITF-14 is designed for trade-item groupings.
• Logistics labels: GS1-128 can carry SSCC, batch, expiry and weight data.
• Consumer links: QR Code can point to a product page, manual, warranty form or GS1 Digital Link URL.

Print size, DPI and quiet zone tips

For print, the quiet zone is just as important as the bars. Keep clear space to the left and right of linear barcodes so scanners can find the symbol. Avoid stretching only the width or only the height after export; resize proportionally or regenerate the barcode at the intended dimensions.

Use black bars on a white background when scan reliability matters. Dark colours can work, but low contrast combinations, transparent backgrounds on busy artwork, glossy stock and very small symbols can all create failures. A quick scan test on the final label material is better than trusting an on-screen preview.

Why use this instead of a basic barcode site?

This generator is designed around fast live preview, no watermark, private browser-side generation, SVG export, print-oriented PNG settings, and a single page where you can switch symbologies without navigating away. That makes it practical for testing labels, preparing artwork and comparing barcode formats quickly.

For production retail use, pair the image export with official GS1 Australia identifiers and retailer artwork checks. For internal workflows, you can use Code 128, QR Code or DataMatrix values that match your own inventory and document systems.
