BARCODE GARDEN / GUIDE

Barcode or QR: which one?

Choose for your data and your scanner.

Start with a barcode for internal codes

CODE 128 works for short ASCII identifiers such as SKUs, shelf locations, and order IDs. Enter exactly what the receiving system expects. A barcode represents data; it does not register inventory.

Use QR for links and Unicode

QR works for links and Unicode text. This tool encodes your content directly without a shortener or expiring redirect. Your scanner must support QR.

Retail identifiers have separate requirements

EAN-13 and UPC-A have fixed lengths and check digits. Use an assigned number. Generating an image does not grant ownership or register a product. GS1-128 differs from ordinary CODE 128 and is not supported here.
