Free Barcode Generator

Use Code 128 for classic barcode labels — it encodes letters, numbers, and punctuation compactly and every scanner reads it; it is the standard choice for internal SKUs and asset tags. Use QR codes when labels will be scanned by phones, may get dirty or damaged, or need to hold more data: QR codes scan faster from any angle and survive partial damage. Retail products you resell usually keep their existing UPC/EAN manufacturer barcodes.

Yes. Paste up to 50 values — one per line, for example a column of SKUs copied from a spreadsheet — and generate them all at once, then print them as a single label sheet on a laser or thermal printer. For hundreds of items, StockZip generates and prints labels directly from your imported item list, which skips the copy-paste step entirely.

Encode the SKU or a short unique ID — not the item name, price, or description. The barcode only needs to identify the item; your inventory software holds everything else and stays editable without reprinting labels. Keep SKUs consistent (for example TOOL-DRILL-01) and avoid special characters that some scanners misread. If you do not have SKUs yet, an ascending code like STZ-0001 works fine.

Click "Print label sheet" to open a printable grid — it works with a normal laser or inkjet printer on plain paper or adhesive label sheets (such as Avery templates), and with thermal label printers via your browser print dialog. For single labels, download the PNG and place it in your label template at the size you need. Test-scan one printed label before printing hundreds.

Print the labels, stick them on items or bins, and connect them to software that updates stock when you scan. In StockZip you can import your item list from a spreadsheet, and scanning a label with your phone camera pulls up the item to check in, check out, or adjust — free for up to 100 items.
